Entire test performed in-house
Analytical Validity: Help
The most common mutation, C282Y (Cys282Tyr) is found in the homozygous state in 89-90% of patients with typical hemochromatosis. The homozygous C282Y genotype confers an approximately 50% risk of abnormal serum iron binding. A second mutation, H63D (His63Asp) has also been associated with hemochromatosis. Less than 2 percent (<2%) of … View more
