11Q Aberrations by FISH
Ordering Recommendation
Facilitates diagnosis of high-grade B-cell lymphoma with 11q aberrations. Detects gain of MLL(KMT2A) in the 11q23 region and loss of FLI1 in the 11q24.3 region.
New York DOH Approval Status
Specimen Required
Tumor tissue.
Formalin fix (10 percent neutral buffered formalin) and paraffin-embed specimen. Protect paraffin block from excessive heat. Transport tissue block or 6 unstained (3-micron thick sections) positively charged slides in a tissue transport kit (ARUP supply #47808) available online through eSupply using ARUP ConnectTM or contact ARUP Client Services at 800-522-2787 (kit is recommended but not necessary). (Min: 3 slides)
Room temperature or refrigerated. Ship in cooled container during summer months.
Specimens fixed or processed in alternative fixatives (alcohol, Prefer) or heavy metal fixatives (B-4 or B-5). No tumor in tissue. Decalcified specimens.
Include surgical pathology report. If multiple specimens (blocks or slides) are sent to ARUP, they must be accompanied by one of the following: an order comment indicating that the ARUP pathologist should choose the specimen most appropriate for testing (e.g., "Choose best block"), or individual orders for each sample submitted. A Pathologist Block Selection Fee (ARUP test code 3002076) will be added to orders that utilize the first option. If multiple specimens are sent to ARUP without a request for pathologist block/slide selection or individual orders, they will be held until clarification is provided.
