is a throat culture test that requires 2-3 days for results. We had a daughter who turned out to be a carrier with no symptoms for months as the strep kept re-occurring in the other kids and wife. She kept coming back negative as we would get everyone tested. Finally, she developed arm twitches and had trouble feeding herself without spilling the food. Couldn't write legibly at school. We ended up referred to a neurologist. Neurologist said let's do a long throat culture. Results were the highest strep count that neurologist had encountered and diagnosis besides strep was Sydenham Chorea. Daughter also had a damaged heart valve. No one in our extended family hesitates when strep is possible.
