Iron status and prevalence of hereditary haemochromatosis in a multiethnic population in northern Norway : the SAMINOR study, the Sør-Varanger study, the Tromsø V study
Iron status is influenced by several factors such as nutritional factors and blood loss. Tron deficiency is one of the most severe and important nutritional deficiencies in the world today, both in industrialised as well as developing countries [1-3]. In normal subjects the total daily loss of iron...
