What Does This Test Measure?

This test detects the concentration of a copper-binding protein in your blood. This protein helps transport copper in the body and also has antioxidant properties. Abnormal levels may indicate conditions like Wilson’s disease, liver disorders, or iron metabolism issues.

Why Might Your Doctor Order This Test?

Your doctor may recommend this test if you have symptoms like fatigue, liver problems (such as jaundice or abdominal pain), or if they suspect conditions like hemochromatosis (iron overload) or Wilson’s disease. It may also be used to monitor treatment progress for these conditions.

Common Conditions This Test Helps Identify

Elevated levels might suggest liver disease, Wilson’s disease, or other metabolic disorders. Lower-than-normal levels could indicate liver dysfunction or certain genetic disorders. Always discuss results with your healthcare provider.

How Is This Test Done?

A blood sample is drawn from a vein in your arm. The sample is then processed to measure the protein concentration using a specialized laboratory method. The test is typically done in a lab and results are usually available within a few days.
