[Serum-ferritin assay in patients over seventy. A study on fifty-eight non anemic subjects and thirty-five anemic patients (author's transl)].
An immuno-enzymatic assay of serum ferritin was performed in subjects over 70 years of age. Wide variations in serum ferritin levels were demonstrated in the non-anemic group (17-510 ng/ml). This makes interpretation of results very difficult. In anemic patients a negative correlation was found between serum ferritin levels and TIBC (Total Iron Binding Capacity). When TIBC is under 42 mumol/l or above 63 mumol/l the two values are so closely correlated that serum ferritin assay does not provide any additional information for the diagnosis of anemia. On the contrary when TIBC is between 42 and 63 mumol/l serum ferritin can allow an estimation of tissue iron storage particularly in absolute iron deficiencies.
