| Interpretation : ----------------------- Result Comments ----------- --------------------- Mycobacterium tuberculosis Infection likely with any of the following species M. tuberculosis, complex- Detected M. bovis, M. microti and M. africanum Non tuberculous Mycobacteria Infection likely with Mycobacterium other than tuberculosis detected complex. Inhibition detected Inhibitors detected in the sample provided. Repeat sample is recommended. Mycobacterium tuberculosis complex Mycobacteria not detected in the sample provided. & non tuberculosis Mycobacteria- Not detected Note ---------- 1. This test includes 3 targets of which 2 are for Mycobacterium tuberculosis complex (IS6110 & MPB64) and 1 target for Mycobacterium genus (16sRNA) 2. Limit of detection of the assay is 1-10 Mycobacteria per PCR. 3. This test does not differentiate between the Mycobacteria species. 4. Mycobacterium culture is recommended in case inhibition is detected. Comments ---------------- Mycobacterium tuberculosis complex ( M. tuberculosis, M. bovis, M. microti & M. africanum) are the only Mycobacteria that are transmitted from person to person and therefore are of public health importance. Non tuberculous Mycobacteria most commonly encountered are M. avium complex & M. kansasii which causes Pulmonary disease; M. abscessus, M. chelonae, M. marinum & M. fortuitum which cause skin and soft tissue infections. Many of the non tuberculous Mycobacteria are environmental contaminants. Nucleic acid amplification tests provide direct detection of various Mycobacteria. |
Why is the Test Done?
This test is used for diagnosis and confirmation of infection by Tuberculosis. It also helps in monitoring treatment of tuberculosis. This is primarily an infection of lungs transmitted from respiratory droplets of an infected person.
