PCR — or reverse transcription-polymerase chain reaction — tests can detect small amounts of the coronavirus’ genetic material in a specimen collected from a human. The test then works by amplifying, or making copies of, that genetic material if any is present in a person’s sample, according to the US Centers for Disease Control and Prevention.
The test’s amplifying property enables it to detect very small amounts of coronavirus in a specimen, “making these tests highly sensitive for diagnosing COVID,” according to the CDC.
While this sensitivity can be advantageous for detecting coronavirus after a recent exposure, it also means PCR results can be positive even after you’re no longer contagious.
