RESUMEN
Objective To explore protein microarray chip diagnostic value for patients with active and inactive tuberculosis.Methods 178 cases of active patients tuberculosis and 79 cases of inactive tuberculosis patients and 92 cases of healthy control using protein microarray chip detection.Results Tuberculosis protein chip had a diagnostic value for tuberculosis and the positive rate is 58.4%; combined the diagnostic value of three kinds of proteins is higher than the diagnostic value of a single protein;16 kD protein of inactive tuberculosis positive rate was 16.4%, better than the positive rate of 3.4% for active tuberculosis (P<0.05).Conclusion Tuberculosis protein chip has a diagnostic value for active tuberculosis and inactive tuberculosis.16 kD protein positive rate more than 38 kD protein in patients with inactive tuberculosis (P<0.05).
