universal donor (y 'nə-vûr'səl) Pronunciation Key
A person who has group O blood and is therefore able to serve as a donor to a person with any other blood type. Group O blood contains red blood cells that do not have the antigen A or B and thus do not react with antibodies to these antigens found in the plasma of the other blood types. See also blood type. |
