Why is wilson's disease found?

Treatable killer. This may be the most treacherous of all diagnoses. 1 in ~60000 people have this defect in copper metabolism that may have no symptoms or look like something else until it ruins the liver and brain. It's picked up on lab testing and even these are fraught with pitfalls. Diagnosed, it's very easy to treat. I wish you luck and hope your workup is done well.
