New ASH Guidelines Recommend Higher Ferritin Thresholds for Iron Deficiency Diagnosis

The American Society of Hematology (ASH) has released new evidence-based guidelines for diagnosing iron deficiency, published in the journal *Blood Advances*. These guidelines recommend higher serum ferritin thresholds for several patient groups, aiming to improve the early detection of iron deficiency, even in individuals without anemia. The recommendations are intended to support clinical decision-making and help identify depleted iron stores earlier.
