After reviewing your symptoms, the doctor will ask if you might recently have been exposed to someone with strep throat or any other infection involving the throat, nose or ears.
After recording your temperature, your doctor will examine you, paying particular attention to your mouth, throat, nose, ears and the lymph nodes in your neck. If your doctor is quite sure that you have strep throat, he or she may prescribe antibiotics without further testing. If there is some uncertainty, the doctor may want to do a strep test.
A rapid strep test is done in your doctor's office, takes only a few minutes to do and detects 80% to 90% of all cases of strep throat. If this quick test is negative, but your doctor still believes you might have strep, your doctor will take a sample of your throat fluids for more intensive testing in a laboratory. Results will be available in 24 to 48 hours.
