Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.

A pathology/diagnostic report including a brief history is required.

 

Specimen Type:

Preferred: Formalin-fixed, paraffin-embedded (FFPE) tissue with a minimum of 5% tumor cell population

Acceptable: Unstained slides with a minimum of 5% tumor cell population; slides may be stained and/or scraped

Container/Tube: Pathology Packaging Kit (Supply T554) requested, but not required

Collection Instructions:

1. Process all specimens into FFPE blocks prior to submission.

2. If submitting slides, a minimum of ten, 4- to 5-micron thick, unstained slides are required.

Additional Information:
