Type B-: Phoenix
Like the phoenix, the B- blood group makes up a small but mighty portion of the population, weighing in at just 1.5% in US. Though you are part of the second rarest blood group, your donations can be used like a phoenix to generate new life for those patients with all B and AB blood types. Looking to make an even bigger blaze? B- donors are well-suited for apheresis platelet donations and double red blood cell donations.
