The RT-PCR (Reverse Transcription Polymerase Chain Reaction) test for COVID-19 is a widely used diagnostic test that detects the presence of the SARS-CoV-2 virus, which causes COVID-19. It is considered the gold standard for COVID-19 testing.
The RT-PCR test is highly sensitive and specific, capable of detecting even small amounts of viral genetic material. It is used for diagnosing active COVID-19 infections, confirming cases, and monitoring the spread of the virus. It is important to note that the RT-PCR test detects the presence of the virus at the time of testing and does not provide information about past infections or immunity.
