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. Many fixatives, such as Hollandes, contain high levels of copper. Any object that has been exposed to these fixatives (e.g., cutting boards, towels, containers, utensils) and comes in contact with the tissue can potentially contaminate it. Rinsing and washing will not remove copper contaminant. Any container that has been previously filled with a copper-containing fixative can contaminate the tissue. Formalin will leach trace amounts of copper out of the plastic. Therefore any plastic containers should be new.
