NettetPCR involves a process of heating and cooling called thermal cycling which is carried out by machine. There are three main stages: Denaturing – when the double-stranded template DNA is heated to separate it into two single strands. Annealing – when the temperature is lowered to enable the DNA primers to attach to the template DNA. Nettet6. apr. 2024 · The most used diagnostic method within this category is the well known polymerase chain reaction (PCR) test. These tests function by detecting the genetic material of the COVID-19 virus within a test sample, and then subsequently amplifying or producing multiple copies of it, to yield a positive signal. If a person is not infected by …
