Iron Deficiency and Iron Deficiency Anemia During Pregnancy: Screening and Supplementation

The U.S. Preventive Services Task Force (USPSTF) concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for iron deficiency and iron deficiency anemia in pregnant people to prevent adverse maternal and infant health outcomes.

This recommendation applies to pregnant adolescents and adults without signs or symptoms of iron deficiency and iron deficiency anemia. It does not apply to pregnant people who:

• Are severely malnourished
• Have symptoms of iron deficiency or iron deficiency anemia
• Have specific hematologic conditions (like sickle cell disease) or nutritional deficiencies that may increase their need for iron

The Task Force points out that there’s a need for further research to assess the benefits and harms of screening and treatment for asymptomatic pregnant people and their infants.
