How the Test Works

A small sample of your respiratory secretions (e.g., nasal swab or throat swab) is collected and tested using a molecular probe. This probe looks for specific genetic material (RNA) from viruses that may be causing your symptoms.

Sample Collection

You’ll likely have a quick, painless swab of your nose or throat. The sample is then sent to the lab for analysis.

What It Measures

The test detects the presence of viral RNA, which indicates whether a virus is actively replicating in your respiratory tract.

When You Might Need This Test

Your doctor may recommend this test if you have symptoms like cough, fever, sore throat, or shortness of breath, especially during flu season or if you’ve been exposed to a contagious virus.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Clinical Significance: This test is crucial for diagnosing viral respiratory infections early. It helps determine if antiviral treatments or isolation measures are needed, especially in high-risk groups like the elderly or immunocompromised individuals.

Frequently asked questions

Why was I asked to take this test?
Your doctor may have suspected a viral infection based on your symptoms or exposure history, and this test provides a precise way to confirm it.
What does a positive result mean?
A positive result means the test detected viral RNA in your sample, suggesting you have an active viral infection that may require further medical evaluation or treatment.
What if my results are negative?
A negative result means no detectable viral RNA was found in your sample at the time of testing. However, symptoms may still be caused by other factors, so follow-up care with your doctor is important.
