What tests may be used to find the cause of my sore throat?
Your doctor may do a rapid strep test, a throat culture or both. A rapid strep test will give results fast--usually within about 15 minutes. But the test won't tell if your sore throat is caused by a bacterium other than Streptococcus or if it's caused by a virus. A throat culture takes longer--between 24 and 48 hours--but it's more accurate. If your doctor thinks you may have mono, he or she will probably do a blood test.
