Do You Know Your Blood Type?

Blood is essential to our living, yet I know many people who aren't sure what type of blood is running through their veins. A simple test involving a needle can tell you whether you're a type A, B, AB, or O. If you're a type O, then you're considered a universal donor because anyone can receive type O blood.

I'm type A positive, what about you?

I'm O negative and recently found out that only 15% of the world's pop is O neg and 35% of this pop\u00a0 are of Basque father"s family are Basque !

A negative. And interestingly, not a genetic match to either of my sisters because my parents are mixed type ABO (Spectra explains this beautifully in her comment).

A positive.

Anyone can donate platelets, and they're not type specific, so anyone can receive any kind of platelets. It is a longer process, usually a couple of hours, BUT, you get your blood back, and they have super comfy chairs and you can watch movies! Also, you don't have to wait as long in between donations, it's only a few days.

A+ - I found out when they typed my blood after I donated. Not allowed to donate anymore though - once you've got cancer, they don't want your blood!

I'm O+. Not to be pedantic, but technically O- is the Universal Donor, and not O+. People who are RH negative cannot receive positive blood, but positive people can receive negative if necessary.

i'm A+ too! it's really funny - i've had surgery a few more times in my life than i'd like to admit and i've had blood work done too and only recently did i FINALLY find out what blood type i am. :) at least i know that i'm the same as my mom - so i know that i'm not adopted :)

I'm O but I dont'know if I'm neg or pos. I only just found out when I was pregnant. I've never donated though. I tried in highschool but I didn't weigh enough. Then I tried in collegs, I weighed enough but I was still slightly anemic. I'm not sure where I am on the anemia front but I'm nursing so I don't think it'd be the best idea. My dad is O- and he used to donate all the time, but he took a trip to Tanzania abotu 10 years ago and because one of the innolucations he hasn't been able to give blood. He goes back every few years just to check , it makes him sad since he's a universal donor

Hey - thanks to everyone who explained the blood type biology to me. I'm still confused. I really don't understand unless the hospital made a mistake. I was only told I had A- blood when I was pregnant with my daughter. So I asked my parents what types they had and that's when they told me about their O blood. So I said "how can I be an A- if you are both O?" My mom said somethng about recessive genes explained it. I was 27 and delirious with a new baby. I didn't think about it much again but I do remember teasing them about "are you SURE i'm really yours?" And it was kind of left alone. I look SO much like each of my parents I think someone's made a mistake somewhere along the way. Either the hospital told me wrong or my parents are misinformed about their types. I remember I had to get an extra shot or my daughter did when she was born because I was a negative blood type and my husband is O+. My daughter is O-.

I'm AB+. For all those who are AB (+ or -) and can donate, we're the universal platelet donor and you may want to consider trying a platelet donation. It's something I've done many times, and while it takes a lot longer than a full blood donation it isn't that bad. Platelets are crucial for people undergoing chemo or having surgery, and with a platelet donation they get many times more platelets than they can get from whole blood. Just an idea!

AB-, the rarest, just like pixelhaze said!

AB- the rarest of all! Unfortunately I also don't weigh enough to give blood. I tried to donate once because the frat on campus organizing it told me my weight was fine and to eat a big breakfast. When I showed up for my appointment the nurse sent me back :P

O- I really should donate more but I really really hate needles. I did donate twice but I haven't been able to bring myself to go again. :(

O- I can only seem to remember to donate when I am pregnant or nursing. Not helpful, I know.

I'm O+, but I can't donate blood because I don't weigh enough and I have a genetic clotting disorder (for some reason, my platelets are very very small and misshapen, so it takes longer for me to clot up). I'm not the universal donor though...that would be O-. My mom is O+ and my dad doesn't know his blood type, but we know for sure he's not AB. alliep627: Alytta's partially right about how blood type is inherited. It's more like this: Type A and type B blood types can have one of two genotypes. It's either AA or AO (type A) and BB or BO (type B). Type O blood is always OO and type AB blood is always AB. So if your parents are both O, you'd HAVE to have type O blood. It IS possible for you to have O blood if your parents are both A or B though...are you sure that's not the case with you? Because if your mom has AO blood and your dad has AO or BO blood, you have a 1 in 4 chance of being type O.
