Probes: 6q- [SEC63 (6q21), MYB (6q23)] | ATM (11q22.3) | p53 (17p13.1) | Trisomy 12 (Cen 12) | 13q-/-13 (13q14, 13q34) | CCND1/IgH t(11;14) | Probes may be ordered separately (except 12 and 13 are tested together, and ATM is tested with p53).
Disease(s): Chronic lymphocytic leukemia
Note: This test was previously called CLL FISH Panel (non-New York). It is now New York state-approved and available to all clients.
The CLL FISH panel is used for the detection of chromosome aberrations observed in chronic lymphocytic leukemia/small lymphocytic lymphoma, which are useful in prognosis and prediction of time to treatment in CLL patients when used in combination with other clinical and diagnostic findings. CCND1/IgH is used to rule out mantle cell leukemia/lymphoma.
- Bone Marrow Aspirate: 1-2 mL sodium heparin tube. EDTA tube is acceptable.
- Peripheral Blood: 2-5 mL sodium heparin tube. EDTA tube is acceptable.
- Fresh, Unfixed Tissue: Tissue in RPMI.
- Bone Marrow/ Peripheral Blood Smear or Fresh Tissue Touch Preparation Slides: minimum 4 slides labeled with specimen type.
- Fluids: Equal parts RPMI to specimen volume
- Fixed Cell Suspension: A client fixed cell suspension may be submitted for testing as long as it is received in 3:1 Methanol:Glacial Acetic Acid.
- Paraffin Block: Send paraffin block. Also send circled H&E slide for tech-only (required). Note: Not approved for NYS samples.
- Cut Slides: H&E slide (required) plus 4 unstained slides cut at 4-5 microns. Circle H&E slide for tech-only. Note: Not approved for NYS samples.
- Note: Please exclude biopsy needles, blades, and other foreign objects from transport tubes. These can compromise specimen viability and yield, and create hazards for employees.
