Necessary Information:
Pathology report (final or preliminary) at minimum containing the following information must accompany specimen in order for testing to be performed:
1. Patient name
2. Block number-must be on all blocks, slides and paperwork (can be handwritten on the paperwork)
3. Tissue collection date
4. Source of the tissue
Specimen Required:
This assay requires at least 30% tumor nuclei.
-Preferred amount of tumor area with sufficient percent tumor nuclei: tissue 360 mm(2)
-Minimum amount of tumor area: tissue 144 mm(2)
-If ordered in conjunction with CMAPT / Chromosomal Microarray, Tumor, Formalin-Fixed Paraffin-Embedded, the preferred amount of tissue is 430 mm(2), the minimum amount is 180 mm(2).
-These amounts are cumulative over up to 10 unstained slides and must have adequate percent tumor nuclei.
-Tissue fixation: 10% neutral buffered formalin, not decalcified
-For specimen preparation guidance, see in Special Instructions on Mayo Labs website. For this test, 6mm x 6mm x 10 slides is preferred: approximate/equivalent to 360 mm(2) with the minimum acceptable of 4mm x 4mm x 10 slides: approximate/equivalent to 144mm(2).
