A PCR test based on insertion sequence IS1081 was developed to detect Mycobacterium tuberculosis complex organisms in the peripheral blood. The method was applied to blood samples from immunocompetent individuals with localized pulmonary tuberculosis.
The MTB PCR test for tuberculosis is a molecular based test. This test identifies the type of Mycobacterium and also provides information about the drug resistance.
Positive PCR means MTB is present. Negative PCR means no signs of MTB were detected.
