Specimen Requirements
Collection Instructions

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.

Contraindications
Do not collect specimens from patients who have received gadolinium within the past 48 hours. Gadolinium, a material contained in some contrast media, is known to interfere with most metals tests.
