How the Test Works

A sample of your nasal or throat secretions is collected and analyzed using a molecular probe that binds to viral RNA. If the virus is present, the probe will detect it, confirming infection.

Sample Collection

You’ll likely have a quick swab of your nose or throat. The sample is then sent to the lab for immediate testing, often providing results within hours.

When You Might Need This Test

Your healthcare provider may recommend this test if you have symptoms like cough, fever, or shortness of breath, especially if you’re in a high-risk group for respiratory illnesses.

Symptoms to Watch For

Common symptoms include sudden onset of fever, cough, sore throat, or difficulty breathing. If you’ve been exposed to someone with a respiratory illness, this test can help confirm exposure.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.
