Objective To detect 5 antibodies against tuberculoprotein
LAM
CFP10
ESAT-6 and 2 proteins at molecular weight of 38 kD and 16 kD by a protein chip and explore its clinical value in diagnosis of tuberculosis. Methods The serum antibodies from 50 tuberculosis patients and 80 non-tuberculosis patients were analyzed by this protein chip
and the diagnostic value of the test was evaluated. Results As was shown in the 130 clinical samples
the sensitivity
specificity
accuracy and Youden index of the diagnostic test were 92.0%
77.5%
83.1% and 69.5% respectively. Conclusion The tuberculosis protein chip assay is of high value in diagnosis of both pulmonary and non-pulmonary tuberculosis patients
and has good coincidence with gold standard. It is time-saving and easy to sampling and practicing
and can be regarded as supplemental item for non-pulmonary tuberculosis.
