Collection Info |
Bone Marrow is the tissue of choice for initial diagnosis of most neoplastic specimens. Malignant blood can be used in certain cases to monitor minimal residual disease. Prefer a minimum of 3.0 mL of bone marrow or 5.0 mL of malignant blood. Draw into green-top (sodium heparin) tube(s), invert several times to mix (clotted specimens may not work and can compromise results). Label vial with the patient's name and a unique identifying number (MGHS encounter # or MR #). Maximum time from collection should be 24 hours. SPECIMENS CANNOT BE FROZEN |
