People with O positive blood can receive red blood cells from O positive and O negative donors.

Simple rule

  • O+ recipient: can get blood from O+ or O-.
  • O+ blood can donate to: O+, A+, B+, and AB+ recipients.

Why this matters

O positive is common and often in high demand because it can be given to any Rh-positive blood type, but not to Rh-negative recipients.
