Which type of test is most accurate in diagnosing influenza?

Viral culture tests are an extremely accurate and conclusive method for diagnosing influenza. Viral culture tests can determine the strain of virus and have become the most common test to help identify and track the spread of flu.

What diagnostic tests are used to confirm influenza infection in the developed world?

Direct Fluorescent Antibody Test (DFA)

The DFA test, also known as the immunofluorescent antibody test (IFA), is an antigen-based test routinely employed for diagnosis of influenza virus infections.

Unreliable Accuracy

The results are ready in as little as 15 minutes, but the rapid tests aren’t as accurate as other tests that need to be sent to a lab. Accuracy of rapid flu tests can range anywhere from 50% to 90%, depending on the test, the individual, and the prevalence of the flu in the community.

Can influenza be detected by blood test?

Serology tests look for antibodies to influenza viruses in a blood sample. Antibodies are developed as part of the immune system’s reaction to a viral infection. It can take time for antibodies to form, though, so serology tests are used to identify a prior infection.
