Special Info
Specimen source required. To perform this test it is essential to know whether or not the submitted specimen has been processed (digestion and decontamination procedure). If processed, smear results must be provided as a comment on the test order or requisition. For processed specimens, identify method used for digestion. Delayed turnaround time will occur if the required information is not provided. Unacceptable conditions: Blood, paraffin blocks, stool, swabs, tissue, and urine. NOTE: Body Fluids other than pleural fluid will be run with a disclaimer. This test is New York DOH approved.
Clinical Info
Panel includes PCR testing to detect M. tuberculosis complex isolates and determine possible resistance to rifampin treatment. Test may be ordered for client-processed specimens.
