What's special about group O+ blood?

O+

8.2 days

41.8% of the population in Scotland have group O+ blood.

Group O is the most common blood group in Scotland. As a result, most patients will have group O blood which means hospitals require more group O than any other type. The demand for O+ varies from day to day and depends on the blood group of the individual patients who require transfusions.
