Antistreptococcal esterase distribution in healthy individuals.

The distribution of serum antistreptococcal esterase titers in healthy school children, aged 10 to 12, and in healthy adults was determined by the method used by Hayano and Tanaka. The upper limit of its normal titer value was 600 ASE units in the children and 500 ASE units in the adults, and its diagnostic levels were over 600 ASE units in children and over 500 ASE units in adults. There was no close correlation between ASE and ASO or ADN-B.
