Myelodysplastic Syndrome (MDS), Diagnostic FISH, Varies
Use
This test is useful for detecting recurrent common chromosome abnormalities associated with myelodysplastic syndromes (MDS) or other myeloid malignancies using a panel of FISH probes. It serves as an adjunct to conventional chromosome studies in patients with MDS and is helpful for evaluating specimens in which chromosome studies are unsuccessful. The test also aids in identifying and tracking known chromosome abnormalities in patients with MDS and monitoring their response to therapy.
Special Instructions
Not provided.
Limitations
This test is not approved by the US FDA and should be used as an adjunct to existing clinical and pathological information. FISH is not a substitute for conventional chromosome studies as it does not detect chromosome abnormalities associated with other hematological disorders that may not be included in the panel. The absence of an abnormal clone does not rule out the presence of a neoplastic disorder.
