INTRODUCTION PCR has some stages and

characteristics that lead it to be effective. Despite having some diagnostic difficulties in some cases, applications are so important and so global that the use of this technique can greatly help modern medicine

Tests that use DNA from mother’s blood to determine sex of fetus often effective

• This noninvasive method helps to know fetus sex and possible diseases.

• The increased concentration of cell-free fetal DNA within maternal blood as the fetus and placenta develop in a gestation advanced stage make the perfect results.

• The quantitative PCR in this case is based in a digital image analysis that allows the precise quantification of nucleic acid bands

• The Real-time PCR allows knowing and registering at all times the amplification reaction kinetics.

Polymerase chain reaction is considered as a routine test to detect ocular infectious disease, is a reality to improve patient care. 

Polymerase chain reaction testing

proven for diagnosing ocular infectious disease

PCR was the chief diagnostic tool for identifying  cytomegalovirus and infection with  Toxoplasma.

• The results in this study show us that it is particularly useful for Acanthamoeba, herpes simplex virus, and Chlamydia

The PCR detect the parasite in blood by detecting genes

• In the advantages of PCR is the speed and efficiency by which performs a procedure that once required long and tedious journeys

MedicalUtility

• Contribution of the PCR to the development of new diagnostic strategies. It allows the detection of infectious agents like viruses hepatitis B and C or regions of the genome of  (HIV).

• PCR allows to know the sex of the fetus and possible  sex-linked diseases he may have. All without having to reach the amniotic fluid.

Another application of PCR is at forensic medicine
