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