SARS-CoV-2 Nucleic Acid Gene Detection by Qualitative PCR (Nucleic Acid Amplification Probe)

How the Test Works

The test uses a specialized swab to collect cells from your nose or throat. These cells are then analyzed in a lab to detect the virus’s genetic material. A molecular test called PCR (polymerase chain reaction) amplifies and identifies specific viral sequences using a fluorescent probe to confirm presence.

When You Might Need This Test

Your healthcare provider may recommend this test if you have symptoms of COVID-19, such as fever, cough, or shortness of breath, or if you’ve been exposed to someone with the virus. It’s also used for screening before travel, returning to work, or attending gatherings where COVID-19 precautions are required.

Sample Collection Process

A healthcare professional will insert a long, soft swab into your nose or throat to collect cells. You may experience mild discomfort, but it usually takes only a few seconds. The swab is then placed in a special container for lab testing.

Test Results and Interpretation

Results are reported as either positive (indicating active infection) or negative (no detectable virus). A positive result means you are likely contagious and should follow isolation guidelines. A negative result does not rule out infection if symptoms persist or you were exposed recently.
