The health care provider will perform a physical examine and look inside the throat. The doctor or nurse may gently rub the back of the throat with a cotton swab, so that a sample of tissue can be more closely examined. This is called a throat culture.
A complete blood count may be done to check for signs of infection. An x-ray or CT scan of the neck may show pus in the space between throat and neck.
