Why This Test Is Done

Your healthcare provider may order this test if you have symptoms like sore throat, cough, fever, or difficulty breathing. It helps determine if a viral infection is causing your symptoms and guides treatment decisions.

What to Expect Before the Test

No special preparation is needed. You’ll likely have a swab gently inserted into your throat and nasal passages to collect a sample. This is quick and usually painless.

What Happens During the Test

The swab is placed in a lab for analysis. Results are typically available within 24 to 48 hours, depending on the lab’s process.

What the Results Mean

A positive result means the test detected one or more viruses in your sample. A negative result suggests no detectable virus was found at the time of testing. Follow-up care may still be needed based on your symptoms and medical history.

Clinical interpretation

This test may screen for a broad range of respiratory viruses, including common ones like rhinovirus, respiratory syncytial virus (RSV), influenza, adenovirus, and others. The exact viruses tested can vary by lab and region.
How accurate is this test?
This test is generally reliable but may not detect all viruses or false-positive results can occur. False negatives are more common, especially if symptoms have recently improved or if the sample was collected too early.
