If you have a sore throat, you may need to have a throat swab taken to see if you have a bacterial infection. The doctor or nurse holds your tongue down with a depressor and uses a plastic stick with a sterile cotton end (swab) to collect a fluid sample from your throat. The swab is then sent to a laboratory. The procedure can be carried out quickly in the doctor’s surgery and is not painful. However, you may gag briefly when the swab touches your throat.
