"Upper limits of normal" antistreptolysin O (ASO) and antideoxyribonuclease (ADN) B titers were determined on serum specimens from various age groups of pediatric patients with no history of a recent streptococcal infection and on healthy adult hospital employees. The upper limit of normal value is that level of antibody titer exceeded by no more than 15% of the total subjects in each age group. This value varies with the age of the subject, and the most pronounced differences are between the values of preschool age children, school age children, and adults. The upper limit of normal values for these groups were as follows: preschool age, ASO = 85(100); ADN B = 60(50); school age, ASO = 170(166); ADN B=1 70(166); and adult, ASO = 85(100); ADN B = 85(100).
测定了无近期链球菌感染史的各年龄组儿科患者血清标本以及健康成年医院员工血清标本中“正常上限”抗链球菌溶血素O(ASO)和抗脱氧核糖核酸酶(ADN)B滴度。正常上限值是指各年龄组中不超过15%的受试者抗体滴度超过的水平。该值因受试者年龄而异,学龄前儿童、学龄儿童和成年人的值之间差异最为显著。这些组的正常上限值如下:学龄前儿童,ASO = 85(100);ADN B = 60(50);学龄儿童,ASO = 170(166);ADN B = 170(166);成年人,ASO = 85(100);ADN B = 85(100)。
