Patient Preparation
Gadolinium is known to interfere with most metal tests. If gadolinium-containing contrast media has been administered a specimen should not be collected for 96 hours.
Instructions
1. Two mg of liver tissue is required. This is typically a piece of tissue from a 22-gauge needle biopsy at least 2 cm long. If an 18-gauge needle is used, the tissue must be at least 1 cm in length.
2. Any specimen vial other than a Mayo metal-free vial used should be plastic, leached with 10% nitric acid for 2 days, rinsed with redistilled water, and dried in clean air.
