I am 72 years old and have no idea what my blood type is. Put it on my bucket list to find out.

O- here but also CMV neg, which makes me a very rare donater, my blood is always used within days of giving and goes to either neo-natal or immune compromised patients. Give as often as possible, almost upto 50 donations.

A RH- mother body will form anti-bodies to kill her baby if its blood is + and must receive a shot to prevent this from happening. FYI

Yolanda62, yes this happened to my daughter and I. I am ab - and she is ab +. my blood acted like she was a disease and forced me to give birth 2 months early. very serious and deadly thing. PS she is healthy and fine now.

sorry, brain glitch while typing! AB+ can only give to their own blood type but can receive from ALL other blood types

Tanya, I am not aware of any valid correlation between blood group and intelligence. That sounds rather Hitlerian.

RedFork2012, I thought its the other way round; I was told at the hospital that O neg is the donor.

Yolanda62, My great-aunt was a most motherly woman and I was sad she never had children. At the end of her llife she confided she had 4 ,who all died at birth, before WWI. She called them "blue" babies, which was the name they usedfor it.

OscardelaVeloster, Me too, and it is most unfair! If O neg were common then it would be OK, but it isnt. It is a minority group. So we may be denied the only blood that we can accept because they have dished it all out to people in the other groups. In an emergency situation when there is no time to test people the O Neg will run out first. I think everyone should be tested at birth and TATTOOED with.their group; then they wouldnt need to raid OUR precious stocks!!!

Linda444, those days they gave you a blood test before you were married and your doctor should have explained to your mother and father their blood were not compatible.

Mz. Pami, no one does it's a mystery that's why they try to change your baby's blood at birth if it is Rh negative when they're born and I said over My Dead body.

Taimis@Luka❤, My mom was A+ & dad was O+ but my sister & I are AO+ since we got an A from mom & an O from dad. I don’t know if mom is an AO+ or an AA+ so every one gets a gene from each parent. Her parents came from Denmark & Moravia but both of dad’s parents were from Germany. Don’t know how much ethnicity has on blood type.

Diana Shifley, a blood recipient must have a blood type and an antibody screen for alloantibodies that may have developed after a previous transfusion.

Yolanda62, only subsequent Rh positive babies are affected if the first delivery was an Rh positive baby.
