Unstimulated short term cell culture and chromosome analysis. Fluorescence In Situ Hybridization (FISH) when indicated.
Identification of specific chromosomal abnormalities associated with hematologic disease. Bone Marrow specimens are most commonly sent as part of the evaluation of acute leukemia (lymphoid or myeloid), MDS, or myeloproliferative disorders including chronic myelogenous leukemia, in the latter case to look for a Philadelphia chromosome.

Chromosome Media tube. Sterile syringe rinsed with sodium heparin or green top vacutainer with sodium heparin. All pediatric bone marrow specimens and bone core biopsies must be transported in Chromosome Media available from Specimen Processing. Do not allow specimen to overheat or freeze. Clotted samples, samples containing <5 million dividing cells, and samples that are greater than 24 hours old are suboptimal. Please complete a MiChart test request and submit it with the specimen. A Cytogenetics Laboratory Requisition is available online at: http://www.pathology.med.umich.edu/handbook/Tables/UM_REQ_CYTOGENETICS….
Specimen transport should be arranged so that the specimen is received by MLabs the same day it is collected. Call for a STAT courier if necessary. Collect bone marrow using aseptic technique. Place 1 - 5 mL bone marrow aspirate in a green top (sodium heparin) tube. Invert the tube several times to prevent clotting. Send at room temperature as soon as possible. Do not allow specimen to overheat or freeze. Clotted samples, samples containing <5 million dividing cells, and samples that are greater than 24 hours old are suboptimal.
