When you have too much iron in your blood, it can cause damage to your heart or liver. Am Fam Physician. As a result of the high frequency of hereditary hemochromatosis–associated mutations, the American Medical Association recommended the establishment of guidelines for population screening, as follows: Screening tests for the general population comprise measurement of serum transferrin saturation or serum iron concentration; when transferrin saturation is greater than 60% or greater than 50% in women who are premenopausal, or when serum iron concentration is greater than 150 mcg/dL, other measurements are recommended, Screening and diagnosis cannot be based on single-measurement transferrin saturation or serum iron concentrations, because they can be falsely increased as the result of diet, alcohol consumption, or other liver diseases, Adams and coworkers suggested the introduction of the unbound iron-binding capacity measurement to preselect patients for genotyping If another condition caused hemochromatosis, you may need treatment for that, too.
