Copper, Liver

Diagnostic Use

Copper and iron are measured in liver biopsy samples using ICP-MS. The samples are received frozen wrapped in tin foil.
They must be dried to constant weight, the sample weight obtained, and then digested with concentrated nitric acid to break down the tissue and form a homogeneous solution. Following digesting, the samples are made up to constant volume with Water 1 and assayed as soon as possible. The biopsy sample is for the determination of iron for Hemochromatosis and alcoholic liver disease and copper measurement for Wilsons disease.

Additional Specimen Information

A liver biopsy of 1.5 cm long is required. Sample should immediately be placed on a 5 cm square of aluminium foil. The foil is then folded like an envelope
and placed in a urine pottle for transport to the laboratory.
Put the sample in aluminium foil and send to the Laboratory on ice
Freezing of the sample will prevent bacterial growth and protect the liver sample from contamination by environmental
iron and copper.
Brief clinical details should be included plus ferritin, iron and %saturation levels in
cases of suspected haemochromatosis.
