Limitations
Laboratory test results should always be considered in the context of clinical observations. This test was developed and its performance characteristics determined by med fusion. It has not been cleared or approved by the U.S. Food and Drug Administration
(FDA). The FDA has determined that such clearance or approval is not necessary. This test is used for clinical purposes. It should not be regarded as investigational for research. This laboratory is certified under the Clinical Laboratory Improvement Amendments
of 1988 (CLIA) as qualified to perform high complexity clinical laboratory testing.

Reference Range
An interpretive report will be provided.

Clinical Significance
Deletions of der(9)t(9;22) at band 9q34 have been reported in between 10% to 15% of patients with CML. It appears that the der(9) deletions occur simultaneously with the BCR/ABL translocation and are associated with a poor prognosis.

Performing Laboratory
