Upper Limit of Normal Anti-strepto-polysaccharide(ASP)Level and the Relationship between ASP and Antibodies against Extracellular Antigens : THE 6th CONFERENCE ON PREVENTION FOR RHEUMATIC FEVER AND RHEUMATIC HEART DISEASE

Abstract

Titers of anti-strepto-polysaccharide (ASP), antistreptolysin-O, antistreptokinase and antideoxyribonuclease-B were studied from the sera of 184 healthy school children. The upper limit of normal ASP titers in school children was 1 : 32 in this study, and titers of 1 : 64 or more were considered abnormal . The correlation coefficients between ASP and other antibodies against extracellular antigens were r = -0.04 to 0.06, and therefore it can be considered that ASP shows an independent value from other antibodies.
