CPT code: | 81445 |
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
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.

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.
