Our Recommendation for O Positive Donors

While every donation matters, we do recommend that our O positive donors give whole blood.

We also encourage you to consider our Power Red donation process. What's that? With the assistance of our high-powered apheresis machines located at any of our donation centers, our Power Red donors are able to safely give double the red cells they'd be able to through traditional whole blood donation. Plus, the machine rehydrates you throughout the donation. Pretty cool!
