Epic Lab Code: LAB8427
Downtime Form: A-1a Molecular Pathology/Diagnostics Laboratory Requisition
Molecular Pathology
6004 BT GH
384-9568
Specimen(s):
Formalin Fixed, Paraffin Embedded Tissue Block
10 unstained 5-10 μM slides at 20-25°C and an H&E slide of the tissue
Minimum:
Tumor cells more than 50% of the total tissue and greater than 10mm2 in surface area on the block.
Rejection Criteria:
Specimens fixed in B5 fixative or that have been decalcified will not be accepted. Tumor specimens containing less than 50% tumor cells or are less than 10mm2 in area may be unacceptable.
Delivery Instructions:
Testing is generally not available on a STAT basis. However, expedited testing can be arranged by contacting the Molecular Pathology Laboratory at 384-9568.
Testing Schedule:
Weekly
Turn Around Time:
21 days
Comments:
The Sarcoma Fusion Panel uses massively parallel next generation RNA sequencing that can detect and identify fusions of 24 genes associated with soft tissue cancers.
