O-type people, show yourselves. The time is now to unleash your power and help restore Hawaii’s low blood supply.


With the unique ability to save people with other blood types, we need O donors to come to the rescue of emergency, trauma and infant patients at 18 hospitals across our state. O blood can make the difference between life and death. O-negative blood is accepted by everyone, and O-positive blood can be used by anyone with a positive blood type— which is about 80% of people in Hawaii.

The need is dire.

With the pandemic, Hawaii’s O blood supply has dipped from a comfortable three-day supply to as low as a one-day supply. That’s dangerous.

The solution is you.

To be effective and safe, transfusion treatment relies on blood type compatibility. All blood types are needed and valued, but O-negative and O-positive blood types are in highest demand.

Unleash your superpower!
