Blood type changed during pregnancy

We get a lot of people who think they’re B (+ or -) when they’re actually O (+ or -) or A (+ or -). We also get a lot who think they’re the universal donor (O-) when they’re actually O+ (the most common blood type). Many can also not accurately remember whether they are + or - even if they know their correct ABO group. These are the most frequent mix-ups for some reason.

I’ve noticed this too. I think it’s just human nature to want to feel special or unique, even when it comes to something like blood type. The amount of people that I’ve seen claiming to be the universal donor is very disproportionate to the percentage of the US population that genuinely is O- (between 7 and 9 percent).

Did you see it in writing that you are A negative or did the doctor say that?
I am acquainted with a woman who said something similar (blood type changed during pregnancy) but what actually happened is she developed an anti-E antibody. I know because I'm the one who titered her antibody every month! But I don't say anything due to Hipaa.

A lot of people mistakenly think O+ is the universal donor.

Maybe I’m selfish, but I’d rather be AB+ than O-. It’s more beneficial to the individual. O- can donate blood to anyone with any blood type, but AB+ can receive blood from anyone with any blood type. Those who are O- can only receive O- blood.

Anyone who is O- and needs a blood transfusion will be straight out of luck if they ever have a severe shortage of O-.

I’d rather be type A than be either of those. I believe studies have come out that identify type A as the blood type with the lowest risk for the majority of illnesses and as the most protective against viruses and infections. This was an area of interest and research during the COVID pandemic. I remember people talking about it. Unfortunately, I’m (along with my DH and kids) stuck with O. That genetic lottery business is brutal.

Anecdotal but I know an O+ man who is in his early 80s, still mentally sound, and showing no signs of deterioration while his former wife who was A+ passed away from cancer (that she was originally diagnosed with in her 30s) at age 49.

It might be a coincidence, but every single person that I know of who is type O has some sort of problem with some part of their digestive system/GI tract and experiences digestive symptoms. They usually struggle with spicy or acidic foods and dairy products. It doesn't matter how healthy they otherwise are. This is a common theme.

You have it backwards, non O types were actually overrepresented in COVID hospitalizations.

https://www.hematology.org/newsroom/press-releases/2023/study-uncovers-direct-link-between-blood-group-a-and-a-higher-risk-for-covid-19-infection

It looks like people with non O types are more susceptible to clotting disorders so thay tracks.

https://www.heart.org/en/news/2020/01/23/whats-blood-type-got-to-do-with-clot-risk

So it doesn't seem like O is the bad type to have.

That's literally how I learned about blood types in high school biology. AB+ is the "selfish" blood type, because it can only receive, and rarely gives. And O- is the universal donor, generous and beloved by all.

What data do you have to show this is a "common theme"? I have O type blood, and no GI issues whatsoever, similar to my family members who are also type O. You may need to take a basic statistics and a basic biology class before spreading weird anecdotes.

I LOLed reading this. My husband is O+. There’s so many common everyday foods that he cannot eat without ending up in the restroom for 5 hours afterward. The poor man cannot even have a bite of a cheeseburger and a sip of a milkshake without this happening. (He’s not even lactose intolerant.)

This might be one of the weirder things to get offended over. The PP clearly said that it could be a coincidence and is based on the people (s)he knows. Data is not needed when you’re making a statement based on your own personal experience.

It rings true for my family.

DP. Data is needed when you are making assertions about biology and disease. Obviously.

This is what I'm wondering as well. Why is it being assumed that she forgot her own blood type?
