Reviewer: Vicky LeGrys, DA, CLS(NCA), MT(ASCP)

Hereditary hemochromatosis is a disorder of iron regulation that can over time lead to widespread organ damage, a variety of chronic disorders, and even death. Early detection may permit treatment before the development of substantial iron overload. The laboratory technologist plays a major role in detecting and controlling this disease. In this course, you will learn about the basics of iron metabolism, the signs and symptoms of hemochromatosis, how it is treated, and the laboratory tests and procedures that are vital to its diagnosis and maintenance.
