Collection Info |
Note: Bone Marrow is the tissue of choice for initial diagnosis of most neoplastic specimens. For Bone Marrow testing information please see " Chromosome Analysis, Hematologic, Bone Marrow" in the test directory. Studies on malignant blood can be informative in advanced stages of disease where abnormal cells have infiltrated to peripheral blood. Generally, chromosome analysis will be successful if greater than 10 % blasts are present. Draw blood into green-top (sodium heparin) tube(s), invert several times to mix. Clotted specimens may not work and can compromise results. Other anticoagulants may be harmful to the viability of the cells. Label vial with patient's name and a unique identifying number (MGHS encounter #, or MR#). Maximum time from collection should be 24 hours. SPECIMENS CANNOT BE FROZEN. |
