Throat swab culture
Informed by recognized medical guidance
Overview
A throat swab culture is a simple test where a healthcare provider uses a cotton swab to gently wipe the back of your throat and tonsils. The sample is sent to a lab to see if bacteria (germs) are causing your sore throat. It helps tell the difference between a viral infection (like a cold) and a bacterial infection (like strep throat).
Key facts
- The test is quick, usually taking less than a minute.
- It can confirm if you have a bacterial infection that needs antibiotics.
- Results typically take 24–48 hours.
Yes, throat swabs are very common. Many people with a sore throat have this test to rule out strep throat or other bacterial infections.
Anyone with a sore throat can have a throat swab, but it is most often done in children and teenagers because they are more likely to get strep throat. Adults and older adults may also have the test if their symptoms suggest a bacterial infection.
