PML/RARA (15;17) translocation FISH
|Method||Fluorescent in-situ hybridization|
|Collection Instructions||Bone marrow is the preferred specimen, but heparinized peripheral blood may be submitted if a large number of malignant cells are present.
Collect bone marrow in a syringe, transfer to Dark Green top vacutainer and gently invert the tube several times for good mixing.
