COVID – 19 RT PCR

The COVID-19 RT-PCR (Reverse Transcription Polymerase Chain Reaction) test is a molecular diagnostic test used to detect the presence of the SARS-CoV-2 virus, which causes COVID-19. This test involves collecting a sample, typically from the nose or throat using a swab, and then converting the viral RNA into DNA, which is amplified to detectable levels. RT-PCR is considered the gold standard for COVID-19 testing due to its high sensitivity and accuracy in identifying active infections, even in individuals with mild or no symptoms. The test is commonly used for diagnosing COVID-19, screening for travel, and confirming exposure to the virus.
