Chromosome Analysis, Bone Marrow
Also known as: CHR BM
Use
This test is used for the diagnosis, prognosis, and monitoring of hematopoietic neoplasms. It can help in identifying chromosomal abnormalities associated with conditions like myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML). The detection of recurrent chromosomal abnormalities aids in disease classification and can provide prognostic information.
Special Instructions
Ensure that the sample is not frozen or exposed to extreme temperatures. The laboratory requires clinical indication or reason for testing and specimen type with test order. It's important to indicate if the patient has received a bone marrow transplant and specify the sex of the donor. Uses the Oncology test request form #43099 or ARUP interface for ordering.
Limitations
Analysis is based on culturing living cells, thus turnaround times are averages and can vary. Frozen or clotted specimens, or those with inadequate integrity for cell culture, may not be sufficient for analysis. Blood can be used if bone marrow is unavailable but may not yield the same diagnostic sensitivity. Results require correllation with clinical and other laboratory findings for accurate interpretation.
