FORRELLAT BARRIOS, Mariela. Diagnosis of iron deficiency: essencial features. Rev Cubana Hematol Inmunol Hemoter [online]. 2017, vol.33, n.2, pp. 1-9. ISSN 1561-2996.

It is estimated that one-third of the world's population is anemic, the majority being due to iron deficiency. Iron deficiency anemia is the result of a large negative iron balance period. Iron deficiency anemia rarely causes death, but the impact on human health is significant. In adults, it is associated with fatigue, restless legs syndrome, pica; in neonates, delayed growth and development and, in adolescents, decrements in learning and behavioral abnormalities. No single test is diagnostic of ID unless the serum ferritin is low or the percent transferring saturation is low with an elevated total iron binding capacity are suggestive. Clinical and laboratory features of the disease are discussed.

Palavras-chave : iron deficiency; anemia; serum ferritin; hypoferremia; transferrin.
