The amount of copper in the body is determined by this test. It aids in the diagnosis of illnesses including Wilson disease, osteoporosis, and anaemia brought on by excessive copper levels in the body. Strong bones, energy production, and melanin production are just a few of the essential bodily processes that copper plays a crucial part in. Jaundice, nausea, abdominal pain, difficulty eating or walking, tremors, and behavioural abnormalities are all signs of copper overload (copper toxicity) in the body. Pale complexion, low levels of white blood cells, weakened bones, weariness, and tingling in the hands and feet are symptoms of the deficiency.
