#ExistRefRange>Negative - No Mycobacterium tuberculosis complex rRNA detected by transcription-mediated amplification.
#ExistInterpData>The MTD test is specific for, but does not differentiate among, members of the M. tuberculosis complex. M. celatum and M. terrae-like organisms will cross react if present at concentrations higher than 30 CFU/test. However, those species are rare clinical isolates. Specimens with high levels of nontuberculosis mycobacteria (greater than 1,000,000 cells/test) may cause low-level positive MTD results when M. tuberculosis complex is not present. This test is FDA cleared but is not labeled for use with pleural fluid specimens.
||Unprocessed, refrigerated respiratory specimens are the preferred submissions for this assay. However, processed respiratory specimens will be accepted if refrigerated less than 72 hours and smear result is provided.
The manufacturer has not determined the efficacy of this test when performed on pleural fluid. The performance characteristics of this test were determined by ARUP Laboratories.
For CSF specimens refer to Mycobacterium tuberculosis Amplified Detection, CSF (0060063).
