Why This Test Might Be Ordered

Your healthcare provider may recommend this test if you have symptoms like fatigue, weakness, or skin changes that could be linked to copper imbalance. It may also be checked in cases of liver disease, Wilson’s disease (a genetic disorder affecting copper metabolism), or if you’re taking certain medications that affect copper levels.

What to Expect Before the Test

No special preparation is needed for this blood test. You may have a small needle inserted into your arm to draw blood, and you’ll likely feel a brief pinch. If you’re on blood thinners, let your provider know before the test.

What the Results Mean

Results are compared to a general reference range for healthy adults. Low copper levels may indicate dietary deficiency, malabsorption issues, or certain medical conditions. High levels could suggest liver disease or other metabolic disorders.

Common Conditions Linked to Copper Levels

Abnormal copper levels can be associated with conditions like Wilson’s disease (a genetic disorder causing copper buildup), liver disease, or conditions affecting iron metabolism. Copper deficiency may also lead to anemia or weakened immune function.

Frequently asked questions

What causes low copper levels in blood?
Low copper levels can result from poor diet (especially low intake of copper-rich foods like shellfish, nuts, and organ meats), malabsorption issues (such as celiac disease or gastrointestinal disorders), or certain medications that interfere with copper absorption.
What are the symptoms of copper deficiency?
Symptoms of copper deficiency may include fatigue, weakness, anemia, hair loss, or a weakened immune system. Some people may also experience neurological issues or skin changes, though these are less common.
How is copper deficiency treated?
Treatment for copper deficiency often involves dietary changes to increase copper intake (e.g., copper-rich foods) or supplements under medical supervision. If the cause is malabsorption, your provider may recommend additional tests or treatments for the underlying condition.
