ASH Guidelines on Diagnosis of Iron Deficiency
Over recent years, evolving data on the prevalence of iron deficiency in high-risk groups such as young children, menstruating individuals, and pregnant individuals, together with variable ferritin thresholds used across clinical settings, have highlighted the need for population-specific diagnostic thresholds in identifying affected individuals. The purpose of these guidelines is to provide evidence-based recommendations to support diagnostic decision-making for individuals with suspected iron deficiency, with or without anemia.

Iron Deficiency Initiative
Iron deficiency is one of the most common blood conditions worldwide, yet many people may not know they have it. Testing is often missed, and even when it is done, results are not always understood correctly. ASH is committed to raising awareness about iron deficiency and the ways it can affect daily life and overall health. See how ASH is working to improve care and support for those affected by iron deficiency.
