Diagnostic Value of T-Cell Enzyme Linked Immunospot Assay for Tuberculosis Infection in Pulmonary Tuberculosis and Extrapulmonary Tuberculosis

This study aims to observe and analyze the diagnostic value of T-cell enzyme linked immunospot assay for tuberculosis infection during diagnosis pulmonary extrapulmonary tuberculosis. The objects were 200 cases patients in outpatient department or inpatient our hospital, including 100 with active tuberculosis, Meanwhile, we selected 90 non disease, nontuberculous disease health examination. test was used detect antigen specificity frequency T cells secreting Interferon gamma results analyzed detail. positive rate enzyme-linked group higher than that non-pulmonary healthy control (p<0.05). significantly sensitivity 88.56 % bacteriological 80.25 negative 93.36 respectively 85.67 %, 84.36 89.73 predictive values 93.95 88.79 96.56 while 74.00 80.00 respectively. By comparing there is no significant difference efficiency (p>0.05). In comparison group, result showed efficacy not statistically immunosorbent has ideal sensibility, infection, which can be widely
