Additional information

  Genetic haemochromatosis (GH) is an inherited condition that can cause the body to accumulate too much iron. The standard treatment for GH is removal of blood through venesection. Individuals with GH will usually be monitored for iron overload through their GP or hospital clinic, and will be offered venesection if required.

  Blood from an individual with GH is safe for transfusion as long as the donor meets all other donor selection criteria. However, it is important that GH patients are not under any additional pressure to donate blood. They must be under the care of an appropriate physician who can offer alternative venesection facilities if the donor is unable to donate. For this reason, any patient with GH who has been venesected or who currently requires venesection must be approved by a Designated Clinical Support Officer prior to acceptance.

  Someone who has a diagnosis of GH following genetic testing but who has no iron overloading may be advised by their physician to donate blood, as this will reduce the likelihood of venesection being needed in the future. Donors in this situation can be accepted without Designated Clinical Support Officer referral, as long as they have not been venesected in clinic.

Reason for change:
  Clarification of when referral to DCSO is required prior to donation.
