Throat Culture
Overview & Description
A throat culture is a test to see if a bacterial infection is present in the throat.
Who is a candidate for the procedure?
This procedure is done on a person who has symptoms of a sore throat and who may have a fever. This test is often ordered when a Group A strep infection such as strep throat is suspected.
How is the procedure performed?
A tongue depressor is used to hold the tongue down. A special swab is inserted into the mouth and brushed against the throat and tonsils. The swab is then sent to a laboratory to see if there are any bacteria. Some healthcare providers offices are able to do this analysis onsite.
Preparation & Expectations
What happens right after the procedure?
The procedure only takes a minute. It is usually done in the healthcare provider's office. A person can generally go home right after the throat culture is done. The healthcare provider may prescribe antibiotics for the person to take pending the results of the throat culture. If the result is positive, the person avoid close contact with others for at least 24 hours after starting antibiotics to prevent the spread of this infection.
Home Care and Complications
What happens later at home?
The person can resume their normal activities once they have gotten over their sore throat.
What are the potential complications after the procedure?
There are no complications from the procedure. Having a throat culture done is harmless and only slightly uncomfortable. Sometimes children may gag or even vomit from having the back of their throat touched.
