ISRAEL JOURNAL OF  VETERINARY MEDICINE MORPHOLOGICAL CHANGES IN RED BLOOD CELLS OF BIRDS AND REPTILES AND THEIR INTERPRETATION H. Pendl ARCHEOPTERYX DIAGNOSTICS TM Hematology and Cytology in Birds and Reptile s. Eichenau, Germany  SUMMARY The value of the evaluation of cell morphology in a blood film with special focus on avian and reptilian erythrocytes is demonstrated. In combination with the packed cell volume (pcv) this rapid and low-cost procedure gives useful information on the patient’s condition and helps the practitioner to take first diagnostic and therapeutic measures while awaiting results being done by outdoor laboratories. General principles for the distinction betwee n regene rative and degen erative changes in avian and reptilian red blood cells are explained in crisp tables, figures, and photographs. They are intended for diresct use and should encourage practitioners to include this useful tool in their daily practice routine.  INTRODUCTION Des pit e the tec hno log ical pro gre ss in avian and reptilian hemato log y, time- consuming manual techniques are still necessary to perform a complete blood cell count, which is difficult to do in-house during daily routine. Valuable time is lost with the processing of samples in laboratories, before adequate diagnostic and therapeutic steps can be started. The timely onset of an adequate treatment, however, is vital for the outcome of the case, especially in debilitated patients. Therefore, simple indoor laboratory techniques for a first check up are desirable. Evaluation of cell morphology in a blood film is a rapid and low-cost procedure. In combination with the packed cell volume (pcv) it gives useful information on the patient’s overall condition and helps the practitioner to take first measures while awaiting further detailed results from the laboratory. This paper focuses on the cha rac teri stics and interpret ation of mor pho log ical changes in avian and reptilian erythrocytes.
