I do actually know what all goes into it.
The number was that 32% donate and only 8% of that is usable if I remember correctly, and I believe it was on one of the Red Cross sites. I tried to find that site again with no luck.
That link ( bloodbook ) differs from the Red Cross limitations, and if you ask me is ridiculous. For example according to them I could never donate because I get acupuncture ( I'd have to wait a year after having it done and that won't be happening)... According to that list if I have my ears pierced or a tattoo I can't donate for a year either... these needles are, or should be just as sterile as the ones the blood banks use, if not you need to find a new tattoo person.
Oddly enough I could donate if I'm on anti-depressants, but I can't if I have eczema... If I take diet pills I can donate, which to me is odd because diet pills are not regulated by FDA and could possibly have some issues there, but hey whatever.
I don't trust most "non-profit" groups... this is a prime reason why..

I am not saying in anyway, not to donate blood, I chose not to because I don't want my veins torn up, they use bigger needles for donations, than for clinic draws, and they only hit me properly 20% of the time with a small needle. Blood is needed, and I truly think that people take advantage of that, especially when a "non-profit" organization can afford to pay it's higher employees so much money.
