Does anyone know their LO's blood type? Under what circumstances would one get this info? I would think this is something I should know, but I don't. My DH doesn't know what his own is either. Is that weird or is it just me?

Re: Blood type
My Blog




I found out my blood type when I was pg with DD. I have it written down, but never remember off the top of my head. I do know I am the same as DH, which means DD must be the same as both of us (I think, high school biology was a loooooong time ago).
I have donated blood in the past, so I have been typed before, but I either never asked or never remembered what it was.
Just ask the pedi, and they will tell you what his blood type is.
Like Dana, I am RH-negative (type O-) and I had to get a RhoGAM shot at 28 weeks because my DH is type AB+. They typed Aaron at birth, through the cord blood (prior to donation) and that's how they also did his initial screen (mandatory in NJ, I think).
Aaron is A-. Same blood type as my mom, actually.
Funny story... when I was born, they had to type me because my mom is A- and my dad is O+. They said I was A- like my mom. And for years I thought I was. Until high school biology class where we self tested for A, B or O blood type (couldn't test for negative or positive RH, though). I did the test twice and both time came up as O. So my mom had my pediatrician (I was 17) test me and, yep, I'm O-.
The hospital screwed up. Good thing they got the negative right, since my mom would have needed a Rhogam shot after delivery had I been positive.
I'm fascinated by blood type. I'm the universal donor (O-) and DH is the universal recipient (AB+). He is the 2nd most rare common type (behind AB-) and I'm the 3rd (most think O is the most common, but it's only O+).

LO is A- just like DH and me! They insisted on giving me the Rhogam shot after my m/c even though I knew I didn't need it. I was then insistent about not needing it after LO was born.
Even though LO was A- and the hospital knew it, he always received O- blood in the NICU. I thought that was strange. Why waste O- when the blood type is known?
I have actually checked Caroline's hospital paperwork because I had wondered about this question before. It isn't on there. I wonder if that is because I am B+ and a Rhogam shot wasn't an issue. Or maybe they just don't record it.
I need to make a note to ask the pedi next time we are there.
That IS odd. If both you and DH are A- then your LO would be neg no matter what! Though two A- can have an O- baby (if recessive O). Though perhaps the hospital wanted to cover their butt in case you were fooling around? Semi-serious there... they prob. have to for lawsuit risks.
But VERY odd re: the transfusion of O- when she was typed A-.

Your LO is typed when they are born. This is mandatory with all the other bloodwork at the time of delivery.
Just ask your pediatricain or OB, it should be in their medical records :-)
I work in a lab, and did Blood Banking :-)
I'm sure the first one was simply to cover for lawsuits. But the transfusions - not only was it wasteful, it deprived my husband of feeling useful. I can't donate blood (lived in Europe during Mad Cow period) but DH donates every other month.
This was the *one thing* he could do for our son (I know they wouldn't have used his blood but still).
He still donates religiously but it would have made him feel good to know our son was getting A- blood.
