Notes:
This test is FDA-approved for induced or expectorated sputa. Other clinical samples (e.g. CSF) have not been evaluated.

Rifampin resistance indeterminate or detected results will be referred for additional testing.

It is specific but does not differentiate between species of the MTB-complex. The test has not been evaluated with samples from pediatric patients (< 18 yrs).
