  • Testing of individuals with increased transferrin-iron saturation in serum and serum ferritin

  • With appropriate genetic counseling, predictive testing of individuals who have a family history of HH

  • HFE genetic testing is NOT recommended for population screening

  • This assay will not detect all of the mutations that cause hereditary hemochromatosis. Therefore, the absence of a detectable mutation does not rule out the possibility that an individual is a carrier of or affected with this disease

  • Test results should be interpreted in the context of clinical findings, family history, and other laboratory data. Errors in our interpretation of results may occur if information given is inaccurate or incomplete

  • Rare polymorphisms exist that could lead to false-negative or false-positive results. If results obtained do not match the clinical findings, additional testing should be considered

  • In rare cases, DNA alterations of undetermined significance may be identified. Because of concerns of the overall penetrance of HFE mutations, HFE genetic testing is not recommended for population screening

  • A previous bone marrow transplant from an allogenic donor will interfere with testing. Call 800-533-1710 for instructions for testing patients who have received a bone marrow transplant.
