American Society of Hematology 2026 guidelines for diagnosis of iron deficiency
Powers et al., American Society of Hematology (ASH) · 2026 · Blood Advances
What this work gives Aellic
Suggests a serum ferritin threshold of 30 ng/ml or less instead of 15 ng/ml to diagnose iron deficiency in adults without inflammation, menstruation or pregnancy (conditional recommendation, low certainty). With inflammation it recommends measuring ferritin together with transferrin saturation and sets no fixed threshold; ferritin below 100 ng/ml or transferrin saturation below 20 percent may be considered. Read in the ASH visual summary and teaching slides; the journal text was not accessible.
Where this sits in the engine
This work is on the register, but nothing computes with it today, mostly because the feature it belongs to has not been built yet. It is listed so the numbers on the overview do not claim more than they carry.
