[The clinical significance of detection of anti-PPD-IgG secreting cell, adenosine deaminase and anti-PPD-IgG antibody in pleural effusion].

Enzyme-Linked Immunospot Assay (ELISPOT) were designed in the diagnostic value of tuberculous pleurisy, had a sensitivity of 90% and specificity of 100%. Anti-PPD IgG antibodies detected by ELISA had a sensitivity of 45% and specificity of 86%. For ADA activity in pleural effesion, the sensitivity and specificity were 75%, 79% respectively. Comparing with ADA and ELISA methods, ELISPOT is a more useful method for diagnosis of tuberculosis pleurisy.
