The Test Grade. The Reason Behind It.

Potentially useful for the right buyer, with meaningful evidence, coverage, transparency, access, cost, terms, or privacy tradeoffs to review.

A lower grade does not mean a panel is a bad personal fit. Your Fit Score can be higher when its purpose, price, sample, access, or support matches what you need.
