How the Test Works
The test uses a fluorescent immunoassay method to detect antigens from influenza viruses. A small sample of your nasal or throat secretions is collected and analyzed to identify the presence of these antigens. If the virus is present, the test will show a positive result.
Sample Collection
You’ll likely provide a nasal or throat swab sample. The swab is inserted into your nasal passages or throat to collect respiratory secretions. This is a quick and usually painless procedure.
What to Expect Before the Test
No special preparation is needed for this test. You may feel mild discomfort during sample collection, but it should not last long. If you have a cold or respiratory symptoms, you may be tested sooner rather than later for more accurate results.
What to Expect After the Test
After the test, you can return to your normal activities immediately. Results are typically available within a few hours or the next day, depending on your healthcare provider’s process.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
This test is crucial for diagnosing influenza infections quickly. Early identification allows for prompt treatment with antiviral medications, which can reduce the severity and duration of symptoms. It also helps healthcare providers manage outbreaks and allocate resources effectively.
