What This Test Measures

The test detects genetic material (RNA) from viruses such as rhinovirus, respiratory syncytial virus (RSV), influenza A/B, adenovirus, and others. A positive result means the virus is present in your sample, which may explain your symptoms.

How the Test Works

A small swab is taken from your nose or throat. The sample is analyzed using a molecular technique that amplifies and identifies viral RNA through a fluorescent probe. This method is highly sensitive and specific for detecting viruses.

When You Might Need This Test

Your healthcare provider may recommend this test if you have symptoms like cough, sore throat, fever, or congestion, especially if you’re unsure about the cause of your illness or if you’re at higher risk for complications from respiratory infections.

What the Results Mean

A positive result indicates the presence of one or more respiratory viruses. This can help guide treatment decisions, such as isolating you from others or choosing appropriate antiviral medications if available. A negative result means no detectable virus was found in this sample.

Frequently asked questions

Why was this test ordered?
Your doctor may have ordered this test to confirm a suspected viral infection, especially if symptoms persist or worsen, or if you’re in a high-risk group (e.g., young children, elderly adults, or those with weakened immune systems). Early identification can help manage symptoms and reduce spread to others.
What does a positive result imply?
A positive result strongly suggests a viral infection, but it doesn’t always indicate which specific virus is causing your symptoms. This test helps rule out common viruses and supports further testing if needed. Treatment may focus on symptom relief or antiviral options if available.
How soon will I get results?
Results are typically available within 24 to 48 hours, depending on lab processing times. Your healthcare provider will contact you with the results and next steps.
