Assessment shows ferritin testing influences hemoglobin deferral rates in blood donors, suggesting need for improved protocols.
Iron deficiency was common. Low ferritin donors who paused donation and returned to donate had hemoglobin deferral rates similar to normal ferritin donors. However, many returned early and had high failure rates. Two years after testing, an 11% difference in return rates remained between low and normal/high ferritin donors.
