A member asked:

Is smear (nose and throat) or aso blood test more accurate for finding streptococcus?

A doctor has provided 1 answer

Throat culture: To diagnose acute infection with streptococcus you need throat culture, if the rapid step test is negative. Positive test result on either should be treated as infection. Aso occurs later in response to an infection. It is important to treat acute strep infections to prevent complications such as rheumatic fever.
