Why This Test Is Done
Your healthcare provider may order this test if you have flu-like symptoms such as fever, cough, sore throat, body aches, or fatigue. It’s especially useful in settings like hospitals, clinics, or during flu season when quick diagnosis is needed to prevent spread.
How the Test Works
The test uses a swab to collect a sample from your nose (nasopharyngeal aspirate). The sample is then analyzed in a lab to detect the virus’s genetic material using a specialized probe and amplification technique, allowing for rapid identification.
Sample Collection Process
You’ll likely sit upright while a healthcare provider gently inserts a soft swab into your nose to collect fluid from your nasal passages. The swab is then placed in a container for lab testing. This process is quick and usually painless.
What to Expect After the Test
After the test, you may experience mild discomfort or irritation in your nose, which usually resolves quickly. Avoid blowing your nose vigorously for a few hours afterward to prevent sample contamination.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Clinical Significance
Short name

Frequently asked questions
This test is critical for early diagnosis of influenza, allowing for prompt antiviral treatment to reduce symptoms and severity. It also helps public health officials monitor flu activity and guide prevention efforts.
The test results are typically available within hours, which is faster than traditional culture methods. This speed is important for managing outbreaks and ensuring timely treatment.
