Good to knowOne result rarely tells the whole story. Your provider looks at your results together with your symptoms, exam, and other tests.
What the test is
Wilson disease is a rare inherited condition where copper builds up in the liver and brain.
Why it's done
- Unexplained liver disease in a young person
- Tremor, mood changes, or movement problems with liver disease
- Numbness or anemia after weight-loss surgery or high zinc intake
Getting ready and what happens
- None.
How the test is done
- A health worker cleans the skin, puts a band around your arm, and draws blood from a vein with a small needle. It takes a few minutes.
What the results mean
Low ceruloplasmin
Can point to Wilson disease; a 24-hour urine copper and eye exam may follow.
Low copper
Can cause anemia and nerve problems.
Questions to ask your provider
- What do my results mean for me?
- Do I need to repeat this test or have other tests?
Risks
A blood draw is very safe. You may have slight pain or a small bruise where the needle went in.
