What Does Copper Do in Your Body?
Copper is essential for many bodily functions, including helping your body use iron properly, forming red blood cells, and protecting cells from damage caused by free radicals. It also supports nerve function and bone health.
When Might You Need This Test?
Doctors may order this test if you have symptoms like fatigue, weakness, or unusual hair loss, which can sometimes indicate copper deficiency. It may also be part of a broader evaluation for conditions like Wilson’s disease (a copper storage disorder) or liver issues.
How Is the Test Done?
A blood sample is drawn from a vein, usually in your arm. The serum portion of your blood is then tested for copper concentration using a specialized laboratory method.
What Are Possible Results?
Results are compared to standard reference ranges, but exact values can vary by lab. Abnormally low or high levels may signal underlying health concerns that need further investigation.

Frequently asked questions
Why might my copper level be checked if I don’t have obvious symptoms?
Copper deficiency is rare but can result from poor diet (especially in vegans), malabsorption issues (like celiac disease), or certain medications. Chronic liver disease or kidney problems may also disrupt copper balance.
Eating foods rich in copper (like shellfish, nuts, seeds, and organ meats) can help maintain healthy levels. If you have a known deficiency, your doctor may recommend supplements under supervision.
