Specimen Stability
Methodology	Transcription Mediated Amplification (TMA) Detects Mycobacterium tuberculosis complex In patients with high clinical suspicion of active tuberculosis (symptoms, exposure, medical history), the AMTD can be helpful in identifying Mycobacterium tuberculosis complex more rapidly than traditional culture methods. But in patients with low clinical suspicion, false positives may occur with enough frequency to cause a low positive predictive value with the AMTD test results. Therefore, the AMTD test should not be used in such cases. The AMTD test should not be used as a replacement for the acid-fast bacilli (AFB) smear or culture test. An accompanying AFB smear and AFB culture is required when the AMTD test is ordered.
Days Performed	Results available within 72 hours of receipt. Test performed on mycobacteria culture processed specimen.
Performing Laboratory	Northwell Health Laboratories
CPT
PDM
Result Interpretation Negative The AMTD test cannot differentiate between viable and non-viable organisms and should not be used to monitor treatment response.
