Routine laboratory exams are usually in the normal ranges. The presence of acid-fast-bacilli (AFB) on a sputum smear or other specimen often indicates TB disease and a positive culture for M. tuberculosis confirms the diagnosis.  Other laboratory test include peritoneal fluid or CSF analysis, urinalysis, and Interferon-Gamma release assays.  The Xpert MTB/RIF test is a molecular test that detects the DNA of the M. tuberculosis and<unk> e to rifampin. The use of this test has increased in the past years.
