Downtime Form: A-1a Miscellaneous Request
Molecular Pathology
6004 BT GH
Formalin fixed, paraffin embedded tissue block and 10 unstained 5-10 μM slides at 20-25°C and an H&E slide of the tissue
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.
Testing Schedule:
Turn Around Time:
7-10 working days
Reference Range:
The tissue will be reviewed by a pathologist prior to testing to identify that it contains at least 50% tumor.

This assay detects mutations in codons 12, 13 and 61 (19 mutations in total).
