目的 本县儿童结核病流行情况调查及活动性肺结核诊断方法探讨。方法 采用PPD皮试筛选出强阳性者 ,再用ELISA测其结核抗体 ,寻找活动性肺结核患者。结果 共检测中、小学生 2 40 0 0人 ,PPD皮试强阳性者 134 0人 (5 .5 8% )。对强阳性者做ELISA查结核抗体 ,阳性者 41人 (3.0 6 % )。此 41人经X光检查肺强异常者 34人 (82 .9% )。结论 ELISA法查结核抗体用于诊断活动性肺结核 ,是一有价值的重要检测手段
Objective To investigate the prevalence of tuberculosis in children in this county and to explore the diagnostic methods of active pulmonary tuberculosis. Methods The PPD skin test was used to screen out the strong positives, then the ELISA was used to test the TB antibodies to find out the active TB patients. Results A total of 2 040 primary and secondary school students were tested, and 134 0 (5.58%) were strongly positive for PPD skin test. To strong positive people to do ELISA check tuberculosis antibody, 41 were positive (3.06%). Thirty-one of the 41 were X-ray abnormal lungs (82.9%). Conclusion ELISA method for detecting tuberculosis antibodies for the diagnosis of active pulmonary tuberculosis, is a valuable means of detection
