Additional Information

Test includes: culture, acid-fast smear and concentration if specimen of greater than 1 mL received. Test includes susceptibility testing of potentially pathogenic organism(s) at an additional charge unless specifically declined. 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 Health & Human Services (MDHHS); although there is no charge for testing, MLabs charges a handling fee for processing and forwarding specimens to MDHHS. Non-tuberculosis susceptibility testing is sent to Mayo Medical Laboratories. A subculture of the isolate is kept by the Microbiology Laboratory for further testing, if necessary. By ordering this test the clinician acknowledges that additional reflex testing will be performed and billed at a separate additional charge if indicated.
