FISH, MDS/Myeloid Panel, -5/5q-, -7/7q-, +8,20q-

Test Summary

Prognostic investigation in patients with myelodysplasia or other myeloid malignancies. Among the patients with myelodysplastic syndromes (MDS), 45-50% have a least one chromosome rearrangement, the most common of which can be detected using this fluorescence in situ hydridization (FISH) panel (-5/5q-,-7/7q-,+8,20q-). This panel of FISH probes can increase the detection rate of chromosome abnormalities at diagnosis and aid in follow-up testing for clinically significant chromosome abnormalities in MDS. The identification of the specific chromosome regions involved in a patient's disease may play a significant role in treatment decisions as MDS targeted therapies are developed.
