I just got back from giving blood, something which I haven’t done in a year or so. Anyway, my blood type is A Positive, something I didn’t even know until I joined the Air Force.
A+.
O+ here. The Red Cross loves me.
AB+
The Red Cross couldn’t care less about me. Good for parts though, I guess.
B+. I know this because I go to the Red Cross for platelet apheresis every month or two.
B+ I had to get various blood tests when I was pregnant and that was one of the things they told me.
A-.
I think the Red Cross just calls me so they can stick needles into something.

O+.
I learned my blood type (A+) when I was a child. My father was contesting paternity during my parents’ first divorce, and I overheard a discussion that involved blood types.
Turned out that I probably was his kid after all.
O+. But I haven’t been allowed to donate blood for several years, because of the whole “time spent in the UK” thing. :mad:
Type B- here.
Here’s a fairly interesting chart of how common your blood group is in each population, there was a global map of distribution but I can’t find it. Kind of interesting that blood group B is far more common in Asia than Europe, maybe Genghis Khan was my great great great great great granddad. 
I always did have a strange fascination with small furry hats…
Ah here’s the site I was looking for.
Group B is practically non-existant in the Americas!
B+ here. I tested it myself as part of a lab project in college.
Another AB+ here
O Negative. They really love me.
I’m type A, Rh positive.
And Inigo, your blood is not at all useless! Even if your cells are only good for other AB people, your plasma can be given to anyone, because you have no anti-ABO antibodies.
It’s not just about the cells!
My blood type is like my grades in school - A+ baby.
O+. I’m ridiculously healthy, and a big guy as well. The Red Cross lick their lips when I walk in.
Like everything else about me…A+.
O+ (boring, I know)
