Copper (Blood Test)

A copper blood test measures the amount of copper in your blood. Copper is an essential mineral that plays a key role in the formation of red blood cells, connective tissues, and the absorption of iron. Abnormal levels of copper in the blood can indicate various health conditions, such as Wilson's disease, a genetic disorder that causes copper to accumulate in the liver, brain, and other organs.

During a copper blood test, a sample of blood will be drawn from a vein in your arm using a needle. The sample is then sent to a laboratory for analysis, where the amount of copper in your blood is measured. It is important to follow any pre-test instructions provided by your test provider, such as fasting before the test or avoiding certain medications that can affect the results.

Abnormal results from a copper blood test may require further testing to determine the underlying cause. Treatment for abnormal copper levels will depend on the specific condition diagnosed.
