No totally reliable test for Wilson's disease is known, but levels of ceruloplasmin and copper in the blood, as well of the amount of copper excreted in urine during a 24-hour period, are together used to form an impression of the amount of copper in the body. The most accurate test is a liver biopsy. [5]
Copper is essential to human health as it is a component of many proteins, but hypercupremia (high copper level in the blood) can lead to copper toxicity if it persists and rises high enough. Chronic toxicity by copper is rare. [1] The suggested safe level of copper in drinking water for humans varies depending on the source, but tends to be ...
Ceruloplasmin is the major copper-carrying protein in the blood, and in addition plays a role in iron metabolism. It was first described in 1948. [ 8 ] Another protein, hephaestin , is noted for its homology to ceruloplasmin, and also participates in iron and probably copper metabolism.
Most of the copper (70 – 95%) excreted by the liver is incorporated into ceruloplasmin, the main copper carrier in blood. Copper is transported to extra-hepatic tissues by ceruloplasmin, [50] albumin and amino acids, or excreted into the bile. [19] By regulating copper release, the liver exerts homeostatic control over extra-hepatic copper. [22]
As with most blood tests, false-negatives can happen, meaning results could come back negative when a cancer does exist — although Grail reports that negative cancer test results from Galleri ...
Copper deficiency, or hypocupremia, is defined as insufficient copper to meet the body's needs, or as a serum copper level below the normal range. [1] Symptoms may include fatigue , decreased red blood cells , early greying of the hair, and neurological problems presenting as numbness , tingling, muscle weakness, and ataxia . [ 2 ]

Iron overload (also known as haemochromatosis or hemochromatosis) is the abnormal and increased accumulation of total iron in the body, leading to organ damage. [1] The primary mechanism of organ damage is oxidative stress, as elevated intracellular iron levels increase free radical formation via the Fenton reaction.
