Specimen Requirements

Offsite Collection Instructions

Swab skin over the site of venipuncture with iodoform solution for 1 minute in a 2 inch circular area around vein to be used, using vigorous strokes and working from the center to the periphery. Allow to dry 2 minutes before performing venipuncture. If use of 2% iodine preparation is contraindicated in patients sensitive to iodine, alcohol alone may be used. DO NOT palpitate venipuncture site after preparation. Draw blood into Isolator Tube. Do not refrigerate or incubate. For optimum recovery, send directly to the laboratory. 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 notified before disposal of the original specimen.

Additional Information

Test includes blood culture for isolation and identification, particularly M. avium-intracellulare. 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.
