Arrangements should be made with the laboratory before sending bone marrow. If a specimen is collected over the weekend, please page the technologist on call by dialing 1-888-533-0186. When it stops ringing, enter your phone number, the '#' sign, and hang up. Provide details of clinical information and family history (if applicable).
Obtain 3 cc of first-draw aspirate in a bone marrow media tube available from our lab or a green-top Vacutainer® with sodium heparin. Send the specimen at room temperature. Label tube with patient name and medical record number. (Do NOT use lithium heparin green-top Vacutainer®). DO NOT FREEZE OR CENTRIFUGE THE SPECIMEN.
