Department: Haematology

Clinical Application
Referrals are usually via the local haematology department or consultant specialists.
Referrals from GP's are accepted provided it is clearly demonstrated in the clinical details that the eligibility criteria is met.
Suggested biochemical criteria include elevated, fasting, serum transferrin saturation and persistently raised serum ferritin concentration.
Due to incomplete penetrance of the disease, homozygosity for p.C282Y is not sufficient to diagnose haemochromatosis and this has important implications for molecular genetic diagnostic practices.
