Why Is O Negative the Universal Donor?

Why is O Negative called the “universal donor”?
In this episode of our Blood 101 series, we break down the science behind blood types in a simple (and fun) way—using cookies to explain how it all works.

O Negative blood doesn’t have A, B, or Rh antigens, which means it can be safely given to patients of any blood type. That’s why it’s often used in emergencies, trauma situations, and for newborns when there’s no time to determine a patient’s blood type.

But here’s the challenge: only about 7% of the population has O Negative blood—yet it’s always in high demand.
