Pcr testing mechanism
Splet01. maj 1996 · Purpose: To do a meta-analysis of studies that have evaluated the sensitivity and specificity of polymerase chain reaction (PCR) assay for the diagnosis of human immunodeficiency virus (HIV) infection in adults. Evaluating the performance of PCR is difficult because in certain clinical situations, the sensitivity or specificity of PCR may … SpletMolecular assays, such as RT-PCR, are designed to accurately identify influenza A and B viral RNA or nucleic acids by using conserved gene targets. Some assays will detect influenza A or B viruses but will not determine the influenza A virus subtype, and thus will not be able to indicate if the infection is due to a novel influenza A virus.
