What kind of flu tests are there?

A number of flu tests are available to detect influenza viruses. The most common are called “rapid influenza diagnostic tests” that can be used in outpatient settings. These tests can provide results in 30 minutes or less.

Unfortunately, the ability of these tests to detect the flu can vary greatly. Therefore, you could still have the flu, even though your rapid test result is negative. In addition to rapid tests, there are several more accurate and sensitive flu tests available that must be performed in specialized laboratories, such as those found in hospitals or state public health laboratories.

All of these tests are performed by a health care provider using a swab to swipe the inside of your nose or the back of your throat. These tests do not require a blood sample.
