How the Test Works

The test uses a molecular probe to detect genetic material (nucleic acid) from influenza viruses. A small sample of your respiratory secretions—collected via a nasal or throat swab—is analyzed to see if the virus is present.

What to Expect Before the Test

No special preparation is needed. You may have a nasal or throat swab performed by a healthcare provider. The sample is then sent to the lab for testing.

What the Test Results Mean

A positive result means the test detected genetic material from the influenza virus, suggesting you may have an active flu infection. A negative result means the test did not find the virus in the sample. Results are typically available within 24 hours.

Possible Causes of Positive Results

A positive result could indicate an active flu infection, but it may also occur if you have recently been exposed to the virus. Other respiratory illnesses (like COVID-19 or RSV) could sometimes yield similar results, though this test specifically targets influenza.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Frequently asked questions

Why was I asked to take this test?
Your healthcare provider may recommend this test if you have flu-like symptoms (e.g., fever, cough, sore throat) or if you’ve been exposed to someone with the flu. It helps confirm whether antiviral treatment is needed.
What does a positive result mean for my health?
A positive result means you likely have an active flu infection. Your provider may prescribe antiviral medications to help shorten your illness and reduce complications. Follow-up care depends on your symptoms and overall health.
Can I still get the flu even if my test is negative?
Yes, it’s possible. A negative result means the test did not detect the virus in your sample at the time of testing. You could still be infected or develop symptoms later. Stay vigilant about symptoms and consider vaccination if eligible.
