Evaluation of ALS assay of TB-SA for diagnosis of pulmonary tuberculosis.

Evaluation of ALS assay of TB-SA for diagnosis of pulmonary tuberculosis. J Immunoassay Immunochem. 2015;36(2):119-27 Authors: Jiao J, Wang MS, Yang XG, Wang XF Abstract The study evaluated tuberculosis specific antigen (TB-SA) antibody in lymphocyte supernatant (ALS) assay for diagnosis of pulmonary tuberculosis (PTB). The mean concentration of TB-SA ALS in PTB patients was significantly higher than that of two control groups (non-PTB patients and healthy subjects, P < 0.001). The area under the curve of the ALS assay were 0.960 (0.904-0.988, PTB vs healthy subjects), and were 0.822 (0.739-0.887, PTB vs Non-PTB patients), respectively. Our data indicated the ALS assay for TB-SA can be used as a screening test and is a useful adjunct to current tests for diagnosis of PTB. PMID: 24702118 [PubMed - indexed for MEDLINE]
