Free copper is a biomarker that measures the amount of copper in the blood that is not bound to proteins. Copper is an essential trace element involved in various bodily functions, such as iron metabolism and nerve functions.
Testing for free copper is particularly relevant for individuals with symptoms that may suggest Wilson's Disease, or for those with a family history of this condition. Wilson's Disease is a rare hereditary disorder that leads to copper accumulation in the liver, brain, and other vital organs, which can lead to serious health problems if untreated.
A free copper test can assist in the diagnosis of Wilson's Disease by determining whether abnormal amounts of copper are present in the blood. It also helps monitor the effectiveness of treatment for those already diagnosed with the condition.
A high level of free copper in the blood may indicate Wilson's Disease or other conditions that result in reduced copper excretion by the liver. It may also be indicative of certain forms of liver disease other than Wilson's Disease.
A low level of free copper is usually less concerning, but may suggest malnutrition or copper deficiency, which can itself lead to health problems such as anemia and bone weakness.
