How will I know if my child has strep throat?
Your child’s doctor will perform a test called a throat culture to see if the sore throat is being caused by Streptococcus bacteria. In this test, a cotton swab is rubbed across the back of the throat and is sent to a lab for testing. If the results of the strep test are positive (the child has strep throat), the doctor may prescribe antibiotics for your child. Strep throat is spread through contact with saliva and mucus, and is still contagious until antibiotics have been taken for 24 hours.
