Specimen Requirements

Collection Onsite

A minimum of 2 mg of fresh or frozen liver tissue is required for analysis. This is typically a piece of tissue from a 14-gauge needle biopsy at least 0.5 cm long. If an 18-gauge needle is used, the tissue must be at least 1 cm in length. The 18-gauge needle produces a specimen that is thin and fragile and difficult to handle. Fresh or frozen specimen is preferred. Place specimen in a metal free container and refrigerate.
