Copper in Serum (Mass Concentration)

What Does This Test Measure?

Your blood serum contains copper, which is naturally present in your body. This test quantifies the mass concentration of copper in your serum, typically measured in micrograms per deciliter (µg/dL). Copper is an essential mineral that plays a role in various biochemical processes, including antioxidant defense and iron metabolism.

Why Might You Need This Test?

Doctors may order a serum copper test to investigate symptoms like fatigue, hair loss, or neurological issues that could be linked to copper deficiency or disorders like Wilson’s disease, where copper buildup occurs. It may also be part of a broader evaluation for liver disease or other conditions affecting copper metabolism.

What to Expect Before the Test

No special preparation is usually needed, but you may be asked to fast for 8–12 hours before the test if instructed by your healthcare provider. On the day of the test, avoid consuming foods or supplements high in copper (e.g., organ meats, shellfish, or certain vitamins).

What Happens During the Test?

A healthcare professional will draw blood from a vein in your arm. The blood sample will be sent to a lab for analysis using a specialized method to measure copper concentration accurately.
