[Clinical aspects of the radioimmunological determination of serum ferritin].

Personal experience confirms the diagnostic value of serum ferritin estimation in the iron deficient microcytic anemia, where there are low levels. The clinical significance of the test is restricted by the not negligible incidence of levels like that of iron overload in the hepatic and neoplastic diseases. In hepatic diseases the test resulted to be related to the changes of serum transaminases. In malignant neoplasms the high serum ferritin levels had been only sometimes associated with transfusional siderosis.
