Comments:
The Xpert MTB/RIF Assay is intended for use with specimens from
patients for whom there is clinical suspicion of tuberculosis and who
have received no therapy or less than 3 days of antituberculosis
therapy. This test does not provide confirmation of rifampin
susceptibility since mechanisms of rifampin resistance other than
those
detected by this device may exist. The Xpert MTB/RIF Assay must be
used in conjunction with a mycobacterial culture to address the risk
of
false negative results and to recover organisms for further testing
and
drug susceptibility testing.
This test is for diagnostic purposes and is not a test of cure. Repeat testing after initial positive test will require approval of the pathology resident on call or pager 4290.
