Abstract: Polymerase Chain Reaction (PCR) is a molecular technique more suitable for accurate diagnoses because of its specificity in targeting and identifying specific pathogens. PCR technique is reliable to detect the genetic presence of the virus in the host since the very beginning of the infection, no matter how the immune system of the person might react. Moreover, the samples for the test contains the DNA information during quite a long time since the extraction. Programmable thermal operation cycler for controlling heating and cooling is the procedure to denaturation into two single strands, annealing and extension reactions of the DNA. The PCR is certainly having a clinical approach, because do not emphasized on how the immune system of the patient might reacts to the infection, only on whether the specific virus is present or not for the accurate diagnoses and subsequently proceed with an appropriated medical treatment to restore health.
