Potential impact on blood availability and donor iron status of changes to donor hemoglobin cutoff and interdonation intervals

A minimum male hemoglobin (Hb) level of 13.0 g/dL becomes a Food and Drug Administration requirement effective May 2016. In addition, extending whole blood (WB) interdonation intervals (IDIs) beyond 8 weeks has been considered to reduce iron depletion in repeat blood donors. This study estimates the impact these changes might have on blood availability and donor iron status.
