Specimen Collection Manual and Test Catalog

3 mL bone marrow (minimum 1 mL) collected in heparin syringe. Place the bone marrow in green top sodium heparin tube during off-shifts. 10 mL whole blood (minimum 1 mL) collected in sodium heparin tube.

Clinical history and reason for referral are required with test order. Previous bone marrow transplant or therapy information, if applicable, should be provided with test order.

Room temperature.

Transport immediately after collection. Viability decreases during transit. Send specimen to testing lab for viability determination. Do not freeze. Do not reject.

Frozen specimens unacceptable.

This test may be replaced by one of the following if the completed test cannot be performed from the submitted specimen: a Tissue Culture for Hematologic Disorder code; or with a Cytogenetics Communication, if a communication is required.

CHROMOSOME BONE MARROW OR BLOOD, Myelodysplastic Syndrome (MDS),Myeloproliferative Disorders (MPD),Acute Lymphoblastic Leukemia (ALL),Chronic Myelogenous Leukemia (CML),Philadelphia Chromosome, KARYOTYPE, HEMCR, Quest test code 14600

Chromosome Analysis, Hematologic Malignancy - Cytogenetics of hematologic disorders attempts to define and interpret chromosomal aberrations that occur in neoplastic cells associated with leukemia, lymphoma and other hematologic malignancies. Chromosome abnormalities in cancer cells of patients with malignant hematologic disorders including acute and chronic myeloid and lymphoid leukemias, myelodysplastic and myeloproliferative disorders, lymphomas and unexplained anemias may correlate with the diagnosis, prognosis, treatment and etiology of disease.
