Questions about this test
Why is copper tested with ceruloplasmin?
Most copper in blood is carried by ceruloplasmin. Looking at both helps doctors understand whether copper levels are truly low or high.
Can zinc supplements lower copper?
Yes. High zinc intake over a long time can block copper absorption. Tell your doctor about supplements you take.
Is blood copper enough to diagnose Wilson disease?
No. Doctors also use 24-hour urine copper, an eye check and sometimes a liver biopsy or genetic test.
