FISH, AML/MDS, CEP8, Trisomy 8
Use
This test uses fluorescence in situ hybridization (FISH) to detect trisomy 8 in patients with myeloid disorders. It may be used to complement standard cytogenetic testing to increase detection rate when cytogenetics is unclear or specimen is suboptimal. Identification of trisomy 8 may inform prognosis and aid in follow‑up testing to monitor treatment outcomes.

Special Instructions
Clinical history and reason for referral are required with test order. Prior therapy and transplant history should be provided. If results are not possible, the test may be canceled and replaced with a Cytogenetics Communication.
