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.
