Screening tests help your doctor look for a certain disease or condition before any symptoms appear. This can increase your chance of finding the problem at a curable or more treatable stage.
Hemochromatosis gene (HFE) testing is done to check to see if a person is likely to develop hereditary hemochromatosis. This test checks whether you are a carrier of the defective gene that causes hemochromatosis. HFE testing locates gene mutations that are called C282Y and H63D. The test can usually confirm whether a person has an increased chance for having hereditary hemochromatosis.
HFE testing identifies a genetic risk rather than the disease itself. Even if you have one or more HFE gene mutations, you may never get sick.
