Eligible blood donors of all blood types are invited to give blood through the American Red Cross this spring to help ensure a sufficient supply for hospital patients.

Also, eligible donors can give red blood cells through either a regular whole blood donation or a Power Red donation, where available. Power Red donors give a concentrated dose of red blood cells during a single donation, allowing them to maximize their impact. During this type of donation, red blood cells are separated from other blood components, and the plasma and platelets are safely and comfortably returned to the donor.

Whole blood can be donated every 56 days, up to six times a year, and Power Red donations may be made every 112 days, up to three times per year.

Make an appointment to donate blood by downloading the free Red Cross Blood Donor App, visiting redcrossblood.org or calling 1-800-RED CROSS (1-800-733-2767).
