In 62, we discovered extrapulmonary tuberculosis. Serum levels of immunoglobulin G were monitored in 287 febrile patients, and 68 had extra-pulmonary tuberculosis. Serum concentrations of adenosine deaminase were significantly higher in patients with tuberculosis compared to other patients with fever of unknown origin. Serum concentrations declined during antituberculosis therapy. A correlation with the localization of infection was not found. Levels of immunoglobulin G were higher in patients with tuberculosis. Both tests had high sensitivity and specificity and could therefore be used for screening extrapulmonary tuberculosis; however, they can only be interpreted adequately following a full clinical investigation. %K Tuberculosis %K adenosine deaminase %K immunoglobulin G %K fever of unknown origin %K laboratory tests %U http://www.doiserbia.nb.rs/img/doi/0354-4664/2012/0354-46641202489S.pdf
