The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The Ring Sign bull Ann Emerg Med 1993 Apr22(4)718-20 bull

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The Ring Sign bull Ann Emerg Med 1993 Apr22(4)718-20 bull

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The Ring Sign bull Ann Emerg Med 1993 Apr22(4)718-20 bull

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The Ring Sign bull Ann Emerg Med 1993 Apr22(4)718-20 bull

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The Ring Sign bull Ann Emerg Med 1993 Apr22(4)718-20 bull

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The Ring Sign bull Ann Emerg Med 1993 Apr22(4)718-20 bull

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The Ring Sign bull Ann Emerg Med 1993 Apr22(4)718-20 bull

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The Ring Sign bull Ann Emerg Med 1993 Apr22(4)718-20 bull

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The Ring Sign bull Ann Emerg Med 1993 Apr22(4)718-20 bull

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The Ring Sign bull Ann Emerg Med 1993 Apr22(4)718-20 bull

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The Ring Sign bull Ann Emerg Med 1993 Apr22(4)718-20 bull

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The Ring Sign bull Ann Emerg Med 1993 Apr22(4)718-20 bull

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid

The Ring Sign bull Ann Emerg Med 1993 Apr22(4)718-20 bull

The ring sign is it a reliable indicator for cerebral spinal fluid Dula DJ Fales W Department of Emergency Medicine Geisinger Medical Center Danville Pennsylvania STUDY OBJECTIVE To study the development of a ring sign when blood is mixed with various fluids METHODS One drop of blood and one drop of either spinal fluid saline tap water or rhinorrhea fluid were placed simultaneously on filter paper and the specimens were examined after ten minutes for the development of a ring A variety of filter paper agents were used including standard laboratory filter paper paper towels coffee filters and bed linens RESULTS All fluids when mixed with blood gave rise to a ring sign blood alone did not The type of filter paper did not affect the development of a ring CONCLUSION In this experimental setting the ring or halo sign is reliable for detecting cerebrospinal fluids but is not exclusive for cerebrospinal fluid
