What does testing positive for strep mean?
If you or your child has a positive result on a rapid strep test, it means you have strep throat or another strep A infection. No further testing will be needed. If the rapid test was negative, but the provider thinks you or your child might have strep throat, he or she may order a throat culture.
What test is used to diagnose streptococcal infections?
What is an ASO test and how is it used to detect a strep infection? Antistreptolysin O (ASO) is a blood test used to help diagnose a current or past infection with group A strep (Streptococcus pyogenes). It detects antibodies to streptolysin O, one of the many strep antigens.
Is strep B an STD?

What happens if you are GBS positive?
If a test finds GBS, the woman is said to be “GBS positive.” This means only that she has the bacteria in her body — not that she or her baby will become sick from it. GBS infection in babies is diagnosed by testing a sample of blood or spinal fluid. But not all babies born to GBS-positive mothers need testing.
