Test Overview
BD MGIT, Culture
Isolate and identify mycobacteria
No growth of mycobacteria
* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
Optimal isolation of mycobacteria from tissue is accomplished by processing as much tissue as possible for culture.
Test Details
Preliminary results are reported in 12-24 hours. The health care provider will be notified of positive cultures. Negative cultures are reported after 6 weeks.

Specimen Requirements
Collect tissue into a sterile container with 0.5 mL sterile saline following sterile preparation of biopsy site. DO NOT SEND SWABS. The portion of the surgical specimen submitted for this test should be separated from the portion submitted for other testing. For optimum recovery, send immediately. If specimen must be stored, refrigerate immediately after specimen collection. May be refrigerated up to 24 hrs. Indicate specimen source, collection date/time, current antibiotic therapy, and clinical diagnosis. If an unacceptable specimen is received, the client will be notified and another specimen will be requested before disposal of the original specimen.
Additional Information
Test includes: culture and acid-fast smear. Test includes identification and 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. 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. M. avium complex susceptibility testing is sent to Mayo Medical Laboratories. Rapid growing mycobacteria susceptibility testing performed at UMHS Microbiology department. A subculture of the isolate is kept for 1 year 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.
