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
The 20q chromosome deletion is most frequently seen in myelodysplastic syndrome, acute myeloid leukemia and chronic myeloproliferative disorders. As the sole abnormality, the 20q deletion is associated with a relatively good prognosis. MDS/AML-associated cytogenetic abnormalities including 20q deletion have been reported in multiple myelomas. Due to the relatively small size of the deletion and the lack of banding features on chromosome 20, FISH is particularly useful in detecting this abnormality.

Performing Laboratory
med fusion
