Blood type changed during pregnancy

[Anonymous]

Since we have people's attention here on DCUM to blood types, people reading here ... + or - which is assigned to the D antigen (Rh negative or positive) IS NOT the only antigen that can cause problems.

The more you can know about your blood type, the better.

I’d bring your blood donor card to your next appointment and show it to your doctor. She may take the discrepancy more seriously if she sees that you have good reason to believe that you’re B+.

No. This needs to be resolved ASAP. if the blood draw was for gestational diabetes then OP may not have gotten an accurate result if the samples or records were mixed up.

In that case, my vote is for OP to call the office first thing and ask to speak to the head nurse about verifying the record.

It doesn’t really matter in the grand scheme of things, but my curiosity has been peaked. I wonder if pregnancy can cause something like this and if it will be temporary or permanent.

lol even if this is the height of your curiosity it hasn’t been “peaked” at.

We had lots of identical resume characteristics and, based on genealogy, her family and mine had branched off from each other about 200 years before. So she actually was a very distant cousin.

Same exact grad program and resume? Sounds sus. I’d contact the school as a recruiter and find out for sure.

Your blood type doesn’t randomly change. It is genetic. It stays the same throughout your life like your eye color.

Well your eye color definitely changes throughout life and not just from cataracts. Babies often have blueish or violet eye colors that turn hazel. And hazel eyed people’s eye colors change with their mood - if normally brownish they turn amber or green when they get mad or if normally green they turn blue when they get upset.

Yup, especially when pregnant and your OBGYN needs to decided whether you need a Rhogam shot. It can be life and death for your baby.

If nothing else hopefully the OP learned the difference between piqued and peaked

PP. Lol. She was for real and not impersonating me. No concerns. By resume I meant...same undergrad major at different schools, same MBA, same industry (we worked at competitors), etc. I'd had some other experiences where people thought I was her or saw her name and thought of me. But she was not trying to steal my identity. In fact, she was the longer-term local with greater career success. We are still connected on LinkedIn and if it ever comes up now we can say that we're distant cousins and people like that kind of true, easy explanation. Even though there's 200 years of divergence.

Welll... it seems there w as a mistake. Gently, I might really wonder if my bio dad was who my mother says he is

They can change from a lighter color to a darker color in infants and toddlers because babies do not produce much melanin when they’re first born. That’s why a lot of babies are born with blue eyes that later turn brown (for example). In those babies, it’s not really changing though because their eyes were always going to be brown based on their genetics. Brown is always their actual eye color that their genetics coded for. Once you have your final eye color, it does not truly change (unless you have some sort of medical condition). It’s simply an optical illusion.
