2. The following information must be included in the report provided.

-Patient name

-Block number-must be on all blocks, slides and paperwork (can be handwritten on the paperwork)

-Date of tissue collection

-Source of the tissue



Specimen Required


Preferred:

Specimen Type: Tissue block

Collection Instructions: Submit a formalin-fixed, paraffin-embedded tissue block.

 

Acceptable:

Specimen Type: Tissue slide

Slides: 1 Hematoxylin and eosin stained and 5 unstained

Collection Instructions: Submit 1 slide stained with hematoxylin and eosin and 5 unstained, nonbaked slides with 5-micron thick sections of the tumor tissue.


Secondary ID

Useful For

Therapy selection for patients with cancer (eg, melanomas that may respond to BRAF inhibitors, colon cancers that may not respond to EGFR inhibitors)

 

Aiding in the diagnosis/prognosis of certain cancers (eg, hairy cell leukemia, papillary thyroid cancers, and association with aggressiveness)

 

Aiding in determining risk for Lynch syndrome (eg, an adjunct to negative MLH1 germline testing in cases where colon tumor demonstrates MSI-H and loss of MLH1 protein expression)

 

This test is not intended as a screening test to identify cancer.
