WebThe rRT-PCR test supports the detection of specific regions in the coronavirus nucleocapsid gene and human RNase P with the help of primers and probes. First of all, viral RNA is converted into complementary DNA with the help of the reverse transcriptase enzyme. WebPCR testing has three steps: Material collection, extraction, and PCR. Let’s examine them one by one. The collection stage consists of inserting a swab into the patient’s nose and/or pharynx, to collect material from their respiratory canal. After extraction, the sample will be sent for analysis.
Webtime. RT-PCR has therefore revolutionised the speed and sensitivity of clinical diagnostics and can be adapted to test at large throughput using automation with reduced need for technical expertise. Modern applications of RT-PCR allow the reaction to be monitored during each stage, known as real time RT-PCR. How is RT-PCR performed?
