给核菌素反应对于婴幼儿结核病的诊断很重要。通常感染结核后2～10周结核菌素反应为阳性,但由于种种因素,其反应较弱或呈假阳性,总之不恒定因素较多。最近日本调查的婴幼儿结核菌素反应中,弱阳性和可疑阳性不少(阳性率3.3%,可疑阳性率6.9%)。弱阳性者占33.6%,可疑阳性者占64.5%,重复试验后转为阴性。因此厚生省决定婴幼儿的结核菌素反应,如第一次为可疑阳性或弱阳性,要再次注射结核菌素,如
The reaction to the nucleocapsid is important for the diagnosis of tuberculosis in infants and young children. Tuberculin reaction is usually positive 2 to 10 weeks after TB infection, but due to various factors, its response is weak or false positive, in short, there are more constant factors. In the recent survey of infants and toddlers in Japan, there were many weakly positive and suspicious positives (positive rate 3.3%, suspicious positive rate 6.9%). Weak positive persons accounted for 33.6%, suspected positives accounted for 64.5%, after repeated tests turned negative. Therefore, the Ministry of Health decided to infants and young children tuberculin reaction, such as the first suspicious positive or weak positive, to re-injection of tuberculin, such as
