In situ hybridization (ISH)
Performed
Mon-Fri
Reported
2-5 days
New York DOH Approval Status
Specimen Required
Tissue.
Formalin fix (10 percent neutral buffered formalin) and paraffin-embed tissue. Transport tissue block or 10 unstained 5 micron slides in a tissue transport kit (ARUP supply #47808). Available online through eSupply using ARUP Connect™ or contact ARUP Client Services at (800) 522-2787. (Min: 5 slides) Protect paraffin block and/or slides from excessive heat.
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). Decalcified or frozen 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.
