Additional Information:
Test includes: culture, acid-fast smear and concentration of specimen. Antibiotic susceptibility testing is performed on potentially pathogenic organisms isolated. Susceptibilities are performed on the first organism isolated from a patient and at 2-6 month intervals if that organism continues to be isolated while the patient is on therapy. Organism ID and M. tuberculosis susceptibility testing is sent to the Michigan Department of Community Health (MDCH); although there is no charge for testing, MLabs charges a handling fee for processing and forwarding specimens to MDCH. Non-tuberculosis mycobacteria susceptibility testing is sent to National Jewish Laboratories, rapidly growing mycobacteria susceptibilities are performed in-house, upon request (a subculture of the isolate is kept by the Microbiology Laboratory for 1 year ). By ordering this test the clinician acknowledges that additional reflex testing will be performed and billed at a separate additional charge if indicated.
