I found this article on-line:

What are the signs and symptoms of copper deficiency? Since copper is important for producing ceruloplasmin, the protein that transports iron in the bloodstream, some of the symptoms of copper deficiency come from a lack of available iron. The most common is anemia, or a low red blood cell count. Copper deficiency can also cause a decrease in white blood cell numbers, which can affect immunity to infection.

Lack of copper also affects the central nervous system and spinal cord and can mimic the symptoms of B12 deficiency. A person deficient in copper may experience demyelination of nerves in the brain and spinal cord, which can lead to sensory changes, loss of sensation, difficulty walking, tremor, loss of balance, difficulty swallowing, problems speaking, and depression. The symptoms of a copper deficiency in humans can mimic those of multiple sclerosis.

A person with a lack of copper may also feel fatigued, feel nauseated, and lose pigment in their skin and hair.

I was not aware of that. How many people check for copper deficiency?
