Red cells contain hemoglobin, an iron-containing protein that carries oxygen throughout the body and gives blood its red color. The percentage of blood volume composed of red cells is called hematocrit. Every donor's hematocrit is checked prior to donation and people with a higher hematocrit may be able to donate more red cells.
Double Red Cell Donation
Using an automated process call apheresis, some donors may be able to give a double red cell donation. Automation allows donors to safely donate certain components of their blood in larger amounts. During an automated donation, blood is drawn into a machine which separates the needed component from the rest of the blood. The final component is collected in a donation bag, while the rest of the blood is returned to the donor.
