The AML FISH panel is useful for detecting the prognostically significant cytogenetic FISH abnormalities used in Acute Myeloid Leukemia according to the NCCN guidelines.
Specimen
- Only one specimen tube is required to perform all ordered cytogenetics testing
- The more testing requested, the closer to the optimal volume requirements is required
- Immediately following collection, mix sample by inverting 5 - 10 times to prevent clotting

EDTA whole blood (a chromosome analysis study is not recommended for this specimen type)
Bone marrow
Collect bone marrow aspirate in a sterile Sodium heparin (Na hep) syringe and transfer to a sterile vial/tube
- or -
Collect bone marrow in sterile syringe (non-heparinized) and transfer to a Dk green Sodium heparin (Na hep), no gel
