How do rt-pcr tests work
WebIn order for a virus like the COVID-19 virus to be detected early in the body using real time RT–PCR, scientists need to convert the RNA to DNA. This is a process called ‘reverse transcription’. They do this because only DNA can be copied — or amplified — which is a key part of the real time RT–PCR process for detecting viruses. WebMay 12, 2024 · A positive RT-PCR test for covid-19 test has more weight than a negative test because of the test’s high specificity but moderate sensitivity A single negative covid-19 test should not be used as a rule-out in patients with strongly suggestive symptoms Clinicians should share information with patients about the accuracy of covid-19 tests
