Collection Instructions

Collect bone marrow in Myco/F Lytic bottle or Green top Heparin tube available from MLabs. After collecting specimen, mix tube contents well to lyse blood cells and prevent clotting. Do not refrigerate or incubate; store and transport at room temperature. For optimum recovery, send directly to the laboratory; Myco/F Lytic bottle may be stored up to 16 hours. Label tube with patients name, registration number, and culture number or anatomic site if more than one culture is drawn at one time. Indicate specimen source, collection date/time, current antibiotic or antifungal therapy, and clinical diagnosis. If unacceptable specimen is received, the client will be called and another specimen will be requested before disposal of the specimen.

Additional Information

Test includes culture and identification. 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. 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 a separate additional charge if indicated.
