For all you vampires: Blood facts

Do you know your blood type? Sadly, I didn't know mine until I moved to Mexico and had to get a Mexican driver's license.

I'm AB-positive.

As it turns out, only 3% of the population is AB-positive. AND, those with AB-positive blood can donate plasma to ANY blood type. Who knew?!

More Facts about Blood. (I chose the ones that I found the most interesting.)
  • Every two seconds someone in the U.S. needs blood.
  • The blood type most often requested by hospitals is Type O.
  • Type O-negative blood (red cells) can be transfused to patients of all blood types. It is always in great demand and often in short supply.
  • The average adult has about 10 pints of blood in his body. Roughly 1 pint is given during a donation.
  • All donated blood is tested for HIV, hepatitis B and C, syphilis and other infectious diseases before it can be released to hospitals. 
  • One donation can help save the lives of up to three people.
  • Half of Red Cross donors male, and half are female.
  • Only 7 percent of people in the U.S. have O-negative blood type. O-negative blood type donors are universal donors as their blood can be given to people of all blood types.
  • Forty-five percent of people in the U.S. have Type O (positive or negative) blood. This percentage is higher among Hispanics – 57 percent, and among African Americans – 51 percent.
  • Only 3 percent of people in the U.S. have AB-positive blood type. AB-positive type blood donors are universal donors of plasma, which is often used in emergencies, for newborns and for patients requiring massive transfusions.

  1. I used to give blood regularly. I stopped when we started trying to get pregnant because on any given month I would say, "I HOPE I'm pregnant," and you can't donate while pregnant...

    I kinda felt like it was one of my civic duties, but I'll tell you what - the red cross is worse than the very worst group of tele-marketers. No one has ever harassed me more then them, and it drove me crazy. "Hey people...I'm the one that comes in every 6-8 wks or whatever...go bug the people that NEVER come in!"

  2. Nice post! We try to give every 8 weeks or whatever it is. So easy, so important, and we get cookies! The movie theater near us has started giving free movie tickets if you donate, so added bonus.

    On a related note... Paul feels so strongly about this type of thing that he recently signed up to be a potential donor through Be The Match (bone marrow). Cool, huh?

  3. Nice post! I also give regularly and have O neg.

  4. Sister, it was good to hear that half of all donors are male, while the other half is female.....


  5. I am actually giving today! Boeing sets one up ever 8-9 weeks, and I never miss.
