A copper test is a laboratory test that measures the level of copper in the blood. Copper is an essential trace mineral that plays a vital role in many bodily functions, including the formation of red blood cells, the maintenance of nerve cells and the production of collagen.

Pre-test preparation: No special preparation is typically required for a copper test, but it is important for the patient to inform their healthcare provider about any medications they are currently taking, as some medications can affect the test results.

Testing method: A small sample of blood is taken from a vein in the arm and sent to a laboratory for analysis. The sample is usually analyzed using a device called an atomic absorption spectrophotometer.

Common symptoms for prescribing this test: A copper test may be ordered if a person has symptoms of a condition that affects the level of copper in the blood, such as Wilson’s disease, Menkes disease, or chronic liver disease. It can also be used to monitor treatment of copper-related disorders or as a part of a screening for certain genetic disorder.

Diagnosis: The results of a copper test are used to help diagnose and monitor a variety of conditions, including Wilson’s disease, Menkes disease, chronic liver disease, and copper deficiency. Elevated levels of copper can indicate the presence of Wilson’s disease or chronic liver disease, while low levels can indicate the presence of Menkes disease or copper deficiency.

Reference range: The reference range for copper levels varies depending on the lab and the population being tested, but generally, a normal range is 70-150 mcg/dL.

Normal values: Copper levels are normally between 70-150 mcg/dL.
