Hematocrit and hemoglobin measurements are blood tests. Hemoglobin enables red cells to transport oxygen and carbon dioxide. The hemoglobin is checked before each donation to ensure that the donor has adequate red blood cell levels to donate blood. Blood donors must have a minimum of 12.5 g/dL hemoglobin or a hematocrit of 38% to be accepted for donation. The hematocrit is a measure of the volume that red blood cells take up in the blood. Most men have a hemoglobin of 12.5 g/dL or greater and a hematocrit above 38 percent, but many women naturally have lower hemoglobin/hematocrit levels.

Donors may be deferred from donating due to a low hematocrit (iron) level. This restriction is for the safety of the donor and ensures that after donation, the donor's hematocrit level will still be within the normal range for a healthy adult.

Platelet (apheresis) donors may donate more frequently -- as often as once every seven days and up to 24 times per year. This is because the body replenishes platelets and plasma more quickly than red cells. Platelets will return to normal levels within about 72 hours of donating.
