Upper limit of normal antistreptolysin-O titer in healthy school children.
We studied the level of ASO (anti streptolysin O) titer and throat culture for GABHS (group A beta hemolytic streptococci) in 200 normal healthy school children between 5 to 15 years of age. We noted the upper limit of normal titer of 242 IU in the healthy school children around Mysore city. Throat culture was positive for GABHS in 9% of healthy school children indicating the carrier state.
