PCR/ RT-PCR Testing
PCR tests (also known as “molecular tests”) are the gold standard in Covid-19 testing. PCR is the most reliable and widely available testing method.
 
How accurate are PCR tests?
PCR tests are considered the gold standard in Covid-19 testing. According to the FDA, these tests are so accurate that their results don’t need to be double-checked by repeating the test.
However, PCRs are the most accurate when conducted on patients that have been infected 5-7 days before the test.
