A positive (A+) is the second most common blood type in Oklahoma, present in about 28% of the population. A+ donors can give red blood cells to A+ and AB+ patients, and their platelets are compatible with all Rh-positive patients — making A+ platelet donations especially valuable for Oklahoma hospitals.
A+ donors are particularly encouraged to consider platelet donation. Platelets are in constant demand for cancer patients undergoing chemotherapy, as chemotherapy destroys the body's ability to produce them. A+ platelets can be transfused to A+, B+, O+, and AB+ patients, covering the majority of platelet recipients. A+ platelet donors can give up to 24 times per year, compared to whole blood's 6 times.
A+ donors can receive from A+, A−, O+, and O− donors, giving them flexibility in emergencies. The combination of high prevalence and broad platelet compatibility makes A+ donors a cornerstone of Oklahoma's blood supply — especially for oncology departments at major Oklahoma hospitals.
