分别采用涂片法、培养法、PPD-IgG法、LAM-IgG法和PCR法对73例结核病人和24例非结核病人的不同部位标本进行检测,结果总阳性率分别为21.9%,35.6%,89.0%,64.4%和47.9%,χ2分别法统计分析两两之间有显著性差异(P<0.05);涂片法、培养法、LAM-IgG法特异性高于PPD-IgG和PCR法,分别为100%,96.7%,100%和76.7%,76.7%.由此建议将涂片法、PPD-IgG法(或LAM-IgG法)作为常规检测手段,而目前将PCR法用于该病的诊断并不理想.
Totally 73 specimens of tuberculosis and 24 specimens of non-tuberculosis were detected by smear method, culture method, PPD-IgG method, LAM-IgG method and PCR method. The positive rates were 21.9% 35.6%, 89.0%, 64.4% and 47.9%, respectively. There was a significant difference between any two groups by χ2 statistical analysis (P <0.05); smear method, culture method, LAM- The specificity of IgG method was higher than PPD-IgG and PCR methods, which were 100%, 96.7%, 100% and 76.7%, 76.7% respectively. It is suggested that the smear method, PPD-IgG method (or LAM-IgG method) as a routine test means that the current PCR method for the diagnosis of the disease is not ideal.
