Accessed October 27, 2015.īaker RD, Greer FR Committee on Nutrition American Academy of Pediatrics. Worldwide prevalence of anaemia 1993–2005. 3 Formula-fed infants often receive adequate amounts of iron (average formula contains 10 to 12 mg per L of iron) and thus rarely require further supplementation. 2, 3, 5 Various oral iron formulations and dosing for supplementation and treatment of anemia are listed in Table 4. 2, 3 Table 3includes daily iron supplementation and requirements for children. 22 The AAP recommends that full-term, exclusively breastfed infants start 1 mg per kg per day of elemental iron supplementation at four months of age until appropriate iron-containing foods are introduced. In healthy full-term infants, iron storage from in utero is adequate for the first four to six months of life. Preterm infants (born at less than 37 weeks' gestation) who are exclusively breastfed should receive 2 mg per kg per day of elemental iron supplementation from one to 12 months of age, 2 except for those who have had multiple blood transfusions. Iron is the most common single-nutrient deficiency. Transient erythroblastopenia of childhoodīone marrow disorders (leukemia, myelofibrosis) Red blood cell membrane defects (spherocytosis, elliptocytosis) Red blood cell enzyme defects (glucose-6-phosphate dehydrogenase deficiency, pyruvate kinase deficiency) Isoimmunization (antibody-mediated hemolysis)Ĭongenital hemolytic anemias (spherocytosis, glucose-6-phosphate dehydrogenase deficiency)Ĭongenital infections (including parvovirus B19) Macrocytic anemia, which is uncommon in children, warrants subsequent evaluation for vitamin B 12 and folate deficiencies, hypothyroidism, hepatic disease, and bone marrow disorders. An initial reticulocyte count is needed to determine bone marrow function.

Normocytic anemia may be caused by congenital membranopathies, hemoglobinopathies, enzymopathies, metabolic defects, and immune-mediated destruction. Delayed cord clamping can improve iron status in infancy, especially for at-risk populations, such as those who are preterm or small for gestational age. Preventive Services Task Force found insufficient evidence to recommend screening or treating pregnant women for iron deficiency anemia to improve maternal or neonatal outcomes. Iron deficiency anemia, which can be associated with cognitive issues, is prevented and treated with iron supplements or increased intake of dietary iron.

Preventive Services Task Force found insufficient evidence to assess the benefits vs. The American Academy of Pediatrics and the World Health Organization recommend routine screening for anemia at 12 months of age the U.S. Microcytic anemia due to iron deficiency is the most common type of anemia in children. Characterizing the anemia as microcytic, normocytic, or macrocytic based on the mean corpuscular volume will aid in the workup and management. The evaluation of a child with anemia should begin with a thorough history and risk assessment. It may also signify internal bleeding, kidney disease or malnutrition (where a person's diet does not contain enough nutrients to meet their body's needs).Anemia, defined as a hemoglobin level two standard deviations below the mean for age, is prevalent in infants and children worldwide. The results of an RBC count can be used to help diagnose blood-related conditions, such as iron deficiency anaemia (where there are less red blood cells than normal).Ī low RBC count could also indicate a vitamin B6, B12 or folate deficiency. The normal ranges are a guide and can vary between different hospital laboratories. Women usually have a lower RBC count than men, and the level of red blood cells tends to decrease with age.

The amount of oxygen that's delivered to your body's tissues depends on the number of red blood cells you have and how well they work.Īn RBC count is usually carried out as part of a full blood cell (FBC) count. Red blood cells contain a substance called haemoglobin, which transports oxygen around the body. A red blood cell (RBC) count is a blood test that tells you how many red blood cells you have.
