Flashcard 535: Wilson disease is characterized by _____ urinary copper
Answer: increased
Extra:
* normally copper is secreted into bile and excreted in stool, however, in wilson disease, copper is not incorporated into ceruplasmin and thus not excreted into bile normally, thus kidneys compensate
* Serum copper is decreased; *Urinary copper is increased due to increased free serum copper, which is able to traverse the GMB because it is not bound to ceruplasmin
