Beth, about blood transfusion connection.... my dad was a universal donor, he was type O Rh neg. He donated on a regular basis throughout his lifetime, and I have a brass relief medal which was his, given to him by the Red Cross in commemoration of him donating over gallon of blood. I remember him having it on his keyring when I was little, so who knows how much he eventually donated. (I'm A neg, which is not quite as rare as B neg)
Statistically, people who have either type A, B, or AB have a higher risk of pancreatic cancer. My uncle ~ my father's brother, died of pancreatic cancer. He was not type O.... Don't know what all of this means, but blood type does matter! There was no association seen between Rh type and risk for pancreatic cancer
rocmg, I agree, I was trying to do the right thing, and the R. Cross was completely serious, it was not worth their effort for the amount they were able to get from me. (I was a repeat attempter) I think if a certain amount is not drawn ~ as in just a little dribble into the tube LOL~ it has to be discarded anyway.
