WebWhat are PCR tests? PCR (polymerase chain reaction) tests are a fast, highly accurate way to diagnose certain infectious diseases and genetic changes. The tests work by finding the DNA or RNA of a pathogen (disease-causing organism) or abnormal cells in a sample. WebPolymerase chain reaction (PCR) is a technique used to rapidly increase the number of copies of one specific region of DNA for further analyses ( Figure 20.1. 4 ). Typically the DNA that is used as the starting sample in a PCR reaction is genomic DNA, which would contain all the genes in the organism. PCR uses a special form of heat tolerant ...
