How the Test Works

A small sample of your nasal or throat secretions is collected using a swab. The lab then uses a specialized probe to detect specific viral RNA sequences. This method is highly sensitive and can identify viruses that may not be visible under a microscope.

What to Expect Before the Test

No special preparation is needed. You may have a nasal swab inserted gently into your nose or a throat swab. This is usually quick and painless. If you’re feeling unwell, it’s best to have the test done when you have symptoms.

Common Uses

This test is often used to diagnose respiratory infections, especially when symptoms like cough, sore throat, or fever are present. It can help determine the cause of illness and guide treatment decisions.

When You Might Need This Test

Your healthcare provider may recommend this test if you have symptoms of a respiratory infection, especially if you’re at higher risk for certain viruses (e.g., young children, elderly adults, or those with weakened immune systems).

Clinical interpretation

Frequently asked questions

What does a positive result mean?
A positive result indicates the presence of viral genetic material in your sample, suggesting you may have an infection caused by one of the viruses tested. Your healthcare provider will discuss next steps, such as treatment or monitoring.
What does a negative result mean?
A negative result means the viral genetic material was not detected in this sample. However, it’s possible you still have an infection that hasn’t been detected by this test or has already cleared. Symptoms may improve on their own.
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 once they are ready.
