Course Description: This course offers an in-depth look at the condition of hemochromatosis. It begins with a discussion about normal iron metabolism and continues by explaining the pathophysiology of iron overload that occurs in the condition of hemochromatosis. Clinical considerations and laboratory testing are also discussed.
