[Determinate titer of tuberculosis antibody with cytomembrane antigen].
Using tuberculous cytomembrane antibody and titer determining methodology, serum specimens from 165 pulmonary tuberculosis patients were analysed. The results showed: 75.7% of specimen is in high level, titer > or = 1:400.20% in low level, titer 1:100-1:200.4. 42% negative. This method is more sensitive than usually used PPD and polymeric OT antigen. At the same time, sputum specimens from 406 TB patients were examined for TB bacilli, the result demonstrated that the positive rate of sputum smear in the patients with titer > or = 800 is up to 95.71%-100%.1:400 is 69.86%, 1:100-1:200 is 14%-22.09%, < 1:100 is 10%.
