Serum copper can help investigate suspected deficiency or copper-handling disorders. Much of the copper in blood travels bound to ceruloplasmin.

Understanding the test
Also called Serum Copper
Copper measurement can contribute to evaluation of unexplained anaemia, an absorption problem or a suspected copper-handling disorder. Other mineral supplements are worth reporting.
A clinician may investigate copper status when symptoms or related tests suggest a deficiency or a copper-handling disorder.
Ceruloplasmin, inflammation and other sources of copper exposure can help explain serum results.
Before your sample
Copper alone usually needs no fast. Tell the clinician about copper and zinc supplements and any pregnancy or hormone treatment. Agree the timing of supplements with your prescriber.
A clinician takes a small sample of blood from a vein. The laboratory uses serum, the liquid separated from the blood after it clots.

The circulating level depends partly on ceruloplasmin, a carrier protein. Inflammation and other changes in that protein can alter copper without a simple change in total stores.

Patient questions
Not by itself. Ceruloplasmin, liver findings and sometimes urine copper help put the level into context.
Serum copper is the total copper in the blood, and ceruloplasmin is the liver protein that carries most of it. Because the two usually move together, measuring both helps your doctor tell whether an unusual copper result reflects a real change in copper or simply a change in the carrier protein, and ceruloplasmin is central when Wilson disease is being investigated.
Taking high doses of zinc over time can reduce copper absorption. If you take zinc tablets, lozenges or a multivitamin, share the product and dose with your clinician. This helps them interpret a low copper result and decide whether supplements may be contributing.
