Why This Test Is Done

Your healthcare provider may recommend this test if you have symptoms like a sore throat, cough, fever, or difficulty breathing. It’s often used in settings like urgent care, clinics, or during outbreaks to help diagnose respiratory infections quickly.

What to Expect Before the Test

You’ll likely have a throat swab performed by a healthcare professional. Swab the back of your throat gently, and you may feel a slight tickle or discomfort. No special preparation is needed, but avoid eating or drinking for 30 minutes before the test if instructed.

What Happens During the Test

A healthcare worker will collect a sample from your throat using a sterile swab. The swab is gently rubbed against the back of your throat, and the sample is sent to a lab for testing. The results are typically ready within 24–48 hours, depending on the lab’s process.

What the Results Mean

If the test detects a virus, it confirms the presence of that specific pathogen. If no virus is found, it means the test did not detect any of the viruses included in this panel. Results may not show all possible viruses or bacterial infections, so further testing could be needed if symptoms persist.

Clinical interpretation
