B positive (B+) is found in approximately 9% of Oklahomans. B+ red blood cells can be donated to B+ and AB+ patients, and B+ platelets are compatible with all Rh-positive recipients. Like all blood types, B+ donations are essential to maintaining adequate blood supplies at Oklahoma hospitals.
B+ donors can receive from B+, B−, O+, and O− donors — the widest range of compatible types available to any B-type recipient. For B+ patients in trauma or surgery, B+ blood is the most readily available compatible type. Oklahoma Blood Institute centers maintain dedicated B+ inventory to meet routine surgical and trauma needs.
Because B is less common than A or O, B+ donors are especially encouraged to donate regularly to prevent shortages. Platelet donations from B+ donors are particularly valuable, as B+ platelets can reach all Rh-positive patients (O+, A+, B+, AB+). B+ platelet donors can give up to 24 times per year.
