OR
1-2 ml whole blood collected in sodium heparin vacuum type tube |

|
| Collection Instructions: |
Bone marrow: 0.5-1.0ml bone marrow from 1st or 2nd aspirate. Material submitted for cytogenetic analysis must be from an early aspirate to avoid dilution with blood. Draw sodium heparin solution (1000 USP units/ml) into the syringe to be used for aspiration and then expel (over-heparinization is toxic to the cells). Transfer the marrow to a sterile, Na-Heparin vacuum type tube for delivery to State Lab. If an aspirate is unsuccessful, a 10mm bone core biopsy may be submitted in a sterile transport medium with Na-Heparin.
Blood: Draw blood using aseptic techniques into a sterile Na-Heparin vacuum type tube. Invert tube to mix. If using larger tubes, draw to full volume to avoid over-treatment with heparin. |
| Unacceptable Conditions: |
Bone marrow/blood that is clotted or hemolyzed is not acceptable. Bone marrow/blood must not be frozen. Plasma and serum are not acceptable. |
