Interpretive Data
This test is not FDA approved for specimens other than respiratory sources; however, this assay was validated at ARUP Laboratories for nonbloody CSF specimens.

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.
