Iron level in blood is a reliable diagnostic indicator of various disease states. Increased levels of iron concentration in blood are associated with red blood cell destruction, decreased blood cell survival, acute hepatitis, certain sideroblastic anemias, ingestion of iron-rich diets, defects in iron storage (e.g., pernicious anemia). Decreased levels of blood iron may result from insufficient iron ingestion from diets, chronic blood loss pathologies, or increased demand on iron storage as during normal pregnancy.
