Screening panel detects EGFR and KRAS mutations (pyrosequencing), ALK and ROS1 fusion proteins (IHC).
Polymerase Chain Reaction/Pyrosequencing/Immunohistochemistry
Formalin fix (10 percent neutral buffered formalin) and paraffin embed tissue. Protect from excessive heat. Transport tissue block or 13 unstained 5- micron slides (8 on positively charged slides AND 5 on uncharged slides). (Min: 9 slides: 5 positively charged AND 4 uncharged). Tissue block will be returned after testing. Transport block and/or slide(s) in a tissue transport kit (ARUP supply #47808) available online through eSupply using ARUP Connect or contact ARUP Client Services at (800) 522-2787
Room temperature. Also acceptable: Refrigerated. Ship in cooled container during summer months.
Less than 25 percent tumor. Specimens fixed/processed in alternative fixatives (alcohol, Prefer®) or heavy metal fixatives. 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.
Ambient: Indefinitely; Refrigerated: Indefinitely; Frozen: Unacceptable
