Can o neg blood type drink a pos type?

A person with O negative blood type (also known as the universal donor) can donate blood to people of all blood types, including those with A positive blood type. This is because O negative blood does not have any A or B antigens on its red blood cells, which means that it is compatible with all other blood types. People with O negative blood type are often considered to be universal donors because their blood can be safely transfused to anyone.
