How to Know If You Have Strep Throat

Although it is common to have a sore throat, not every sore throat is caused by strep and there is not just one sign or symptom that absolutely signals a strep throat infection. So how do you know if you have strep throat?
 
A person with strep throat usually has at least two out of four of these signs or symptoms:
 
  • A red and painful throat that begins suddenly
  • A fever above 101ºF (38.3ºC)
  • Red and enlarged tonsils -- there may also be white patches of pus on the tonsils or in the throat
  • Tender or swollen lymph glands in the neck.
     
If the healthcare provider thinks that a person has strep throat, he or she will take a throat swab, which takes a sample of fluids from the back of the throat. This sample will be used for a rapid strep test and/or a throat culture to look for the signs of the bacteria that cause strep throat.
