Last month, I gave blood for the first time. I'm glad I did it, and as a bonus I was finally able to figure out my blood type. Now I'm curious if, based on my blood type, my blood is worth more/less/the same as any other blood type? Which donor types are generally perfered over others? There's the universal and valuable O- of course, but what about the others?
According to my donor card, I'm "B RH NEG", which I'm assuming means I'm B-. Obviously, all healthy donated blood has value - I'm not arguing that. But I'm wondering if my fairly rare blood type means its more or less valuable as a donation? According to Canadian Blood Services
(the organization that handles all blood donations in Canada), B- is the 2nd rarest blood type, and is only posessed by 1.4% of the Canadian population. If I understand everything right, it's also apparently the hardest type to give blood to, as us B-'s can only accept from O- and B-. This means only 8.4% of the population can help me! Yikes! And only 12% of the population can accept B- blood. But this leads me to belive that really, my donated blood isn't really all that useful, compared to some of the other more popular blood types and especially the almighty O-. Or is my logic flawed, and it's relative rareness means it's even more valuable (especially to those with B- blood?) Or is it all a wash in the end?
In the end, it doesn't really matter, because as long as my donations can be useful and help someone, the donation is worth doing. But at the same time, I'm not all that inclined to go to the trouble of finding a clinic and hanging out with a needle in my arm for an hour if they're really thinking "thanks for the thought, but we don't really need you right now."
Does anyone have any experience and knowledge of how the blood people percieve the contributions based on blood type? Does blood of the lesser needed types ever expire and not get used, just because it's not needed? I guess no one would really go out and say "We don't need your (blood) type" as that could hurt donations overall, but really - is there a perception that some blood is better than the others?
