Jennifer S Tirnauer, MD


The diagnosis of iron deficiency is a major public health goal and an important aspect of the care of many adults. This topic will review the causes of iron deficiency in adults and an approach to the diagnostic evaluation. Treatment of iron deficiency in adults is discussed separately. (See "Treatment of iron deficiency anemia in adults".)

Iron deficiency in other populations is presented in separate topic reviews:

Children, diagnosis and prevention of iron deficiency – (See "Iron deficiency in infants and children <12 years: Screening, prevention, clinical manifestations, and diagnosis".)

Children, treatment of iron deficiency – (See "Iron deficiency in infants and children <12 years: Treatment".)

Adolescents, diagnosis and treatment of iron deficiency – (See "Iron requirements and iron deficiency in adolescents".)
