Quizplus · Accepted Answer

Ceruloplasmin is the most appropriate test to confirm copper intoxication suspicion. Ceruloplasmin is an enzyme that contains approximately 90% of the copper in plasma and is essential for the proper incorporation of copper into iron metabolism. Low ceruloplasmin levels are indicative of copper deficiency, while high levels are indicative of copper toxicity.
