What This Test Measures

The test uses a probe-based immunoassay to detect specific antibodies (IgM and IgG) against common influenza virus types. These antibodies signal your body’s immune response to past or recent infection.

Why It’s Ordered

Doctors may order this test if you have flu-like symptoms (fever, cough, sore throat) or if you’ve been exposed to someone with the flu. It helps confirm infection rather than rule it out.

Sample Collection and Process

A blood sample is drawn from a vein, typically in your arm. The sample is tested immediately or stored for later analysis using a probe-based immunoassay to detect antibody presence.

What to Expect Before or After

No special preparation is needed. You may experience mild discomfort at the injection site, but this usually resolves quickly. Results are typically available within 24–48 hours.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Positive results indicate an immune response to influenza, suggesting recent infection. High IgM levels often appear early in illness, while IgG levels rise later. This test supports diagnosis but isn’t definitive alone—symptoms and clinical judgment are key.

Frequently asked questions

How long does it take to get results?
Results are usually available within 24 to 48 hours after testing, though some labs may provide preliminary feedback sooner.
Can I have false positives or negatives?
False positives are rare but possible if you’ve had a recent flu vaccination or exposure to other respiratory viruses. False negatives can occur if testing is done too early after infection.
Does this test differentiate between flu A and B?
No, this test detects antibodies against *all* influenza strains collectively. For subtype-specific identification, additional testing may be needed.
