SARS-CoV-2 Nucleic Acid Detection in Upper Respiratory Specimen (Qualitative PCR)

How the Test Works

The test uses a specialized laboratory technique called polymerase chain reaction (PCR) to identify tiny pieces of the virus’s genetic code. A small sample of your upper respiratory secretions is collected and analyzed to detect the virus’s genetic material, even if you’re not yet showing symptoms.

What to Expect Before the Test

You may be asked to avoid eating, drinking, or using mouthwash for a short time before the test. Your healthcare provider will give you specific instructions based on your situation. The test typically involves a quick, painless swab of your nose or throat.

What to Expect During the Test

The procedure is quick and usually done in a doctor’s office, clinic, or testing center. You may feel mild discomfort from the swab, but it’s not invasive. The sample is then sent to a lab for analysis.

When You Might Need This Test

This test is often recommended 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 may also be used for screening in settings like schools, workplaces, or community gatherings.
