【摘要】 为了评价结核性脑膜炎（结脑）的实验室检查方法，对２０例结脑和２８例非结脑患儿的脑脊液分别进行了ＰＣＲ、抗结核抗体、涂片找结核杆菌及腺苷脱氨酶活性测定。测定结果在结脑组和非结脑组均存在明显差别（Ｐ＜００１），对结脑诊断的敏感性和特异性分别是８５％和８９３％、５５％和８５７％，５％和１００％，８５％和８２１％，其中以ＰＣＲ检查的敏感性和特异性最高，提示ＰＣＲ是快速诊断结脑的可靠方法。更多还原

【Abstract】 For the purpose of evaluating the laboratory tests for tuberculous meningitis, 20 cases tuberculous meningitis and 28 cases non tuberculous meningitis children were studied by polymerase chain reaction,anti-PPD antibody, smear and adenosine deaminase in cerebrospinal fluid. The results showed that all the tests were all different markedly in the two groups. The sensitivity and specificity of the four tests were 85% and 89.3%, 55% and 85.7%, 5% and 100%, 85% and 82.1% reapectively. The polymerase chain reaction were highest in sensitivity and specificity in the four tests. It was suggested that polymerase chain reaction would be the most useful method for the rapidly diagnosis of tuberculous meningitis.更多还原
