By Mayo Clinic staff
Laboratory tests
Samples of fluids from your nose or throat can be tested for the presence of a flu virus. In the past, these types of tests could take hours or even weeks to complete. When more-rapid tests became available, they couldn't distinguish between bird flu and other types of influenza. The Food and Drug Administration recently approved a type of test that can identify bird flu viruses in less than an hour.
Imaging tests
X-rays may be useful in assessing the condition of your lungs, which can help determine the proper diagnosis and the best treatment options for your signs and symptoms.
