How to find out blood type?

71 replies

Busband · 26/01/2025 14:27

DD asked me what hers is and I realised I have no idea what my own is!

apart from giving blood is there any way to find out?

If you have the NHS app, it may be included in your test results. Mine doesn’t go back far enough to include any of my pregnancies.

That said, it will be somewhere in your NHS record. I’ve had several surgeries recently and I had to give consent for blood transfusions if I needed them, and they seemed to know my blood type.

Get married in a country that tests it before marriage! That's how I found out. My husband's country gives the bride and groom a medical before the marriage can go ahead. I turned out to be O- and he is A+ so we were told about the injections during pregnancy. It was even on my work ID card, presumably so a transfusion could be administered without delay if necessary.
I have done quite a lot of reading about rhesus negative blood and ignoring the crazy stuff (reptilian/alien theories), it seems as if there is a correlation between rhesus negative and worse health outcomes such as autoimmune diseases (which I have).
In the Far East it is taken VERY seriously, as they believe your blood group confers personality types and they take it into account when choosing a marriage partner.

Is there a reason, apart from pure interest, that you might want to know?

I found out via a school biology lesson many moons ago....teacher was very pleased with me as I was the only one in the class who was a B.

Fontainebleau007 · 27/01/2025 14:13

I'm also rhesus negative. When my kids were born I was given a card with their blood types
on. I keep them in my purse incase it's ever needed.

No just curiosity really

Tell us more. Do they think they should be the same blood type or different? What are the personality types. It’s so interesting, isn’t it?

Pretty sure it's not in Red Books, they don't do routine blood tests on babies.

Not in my daughter's (she's 6). No idea what hers is.

I can't remember exactly which types are compatible, but from memory, O types are more sociable and outgoing, while A types are more detail-oriented. AB and B's are rarer, I will look it up this evening and get back on it.

@VividBlue A summary of blood types including the Japanese theory. It is prevalent across East Asia though.

I was told my children’s blood groups after they were born and they are both o- like me and their father. It wasn’t written in their baby books though and I’m not sure if it’s noted in their medical records. You’d think it would be seeing as they were tested after birth but for some reason they don’t make a note of it.

dementedpixie · 27/01/2025 19:04

@Linnet if both you and the father are O- then the children will be O- too. They wouldn't need to test them as that's the only option for 2 parents with O- blood

Thanks for that. Being O+ I agree I’m strong-willed not sure about the rest of it, ha.

But this was interesting - ‘Type B has 50,000 times the number of strains of friendly bacteria than A or O types’ . What on earth? Why would that be?

The bit about the mosquitos Is true for my type. I very rarely get bitten by anything.

Sunnyside4 · 27/01/2025 19:47

If you're Rh negative, your her blood group should be on her notes. I'm AB negative and we knew DH was O positive through giving blood. They tested DD after birth and told us there were noconcerns, so I asked then what she was. She's very happy as she's B positive, which she thinks sounds good.

I'd guess if she's ever had a blood test, it'll be on her notes, so GP's surgery might know.

juuuuuust every so often though the father isn't the father and that can throw a spanner in the works!

This has always been an interesting one for us. We lived overseas in an area with a lot of mozzies - DH and DT1 were bitten mercilessly the whole time we lived there, and every time since when we’ve gone back to visit. They both also react badly to bites which swell up massively and at times have become infected. DT2 was hardly ever bitten and never reacted to the bites. Everyone said that they prefer some blood groups over others, but DTs are identical, so it made absolutely no sense whatsoever that one would be so appealing to the mozzies and would then react so badly to their bites, while the other one was completely ignored.🤷🏼‍♀️

Deebee90 · 27/01/2025 20:10

I only found out through a blood test as they rang me to ask me if I knew I was o neg with antibodies. It was very strange but sadly I’ve needed blood transfusions since so knowing my blood type paid off.

Bitteralmond · 27/01/2025 21:14

The mosquitos definitely prefer me to my husband. I also get mouth ulcers and have ulcerative colitis, so the ulcer bit is true too.

Although the character part is pseudo-science, I guessed myself as type O going on what my Korean friends had told me. It turned out to be right, but probably complete coincidence.

I know that but the hospital don’t take it at face value when you tell them that your husband is also o-. They still test the baby once it’s born.

When we had our second baby they had changed the anti-d rules and the rh- mothers were to get extra anti-d injections throughout the pregnancy. When I told the midwife that my husband was o- and I wouldn’t need them they said I still had to have them as they can’t guarantee that the husband is the father of the baby. In the end my husband had a blood tested to prove that he was o- and it was sent to my consultant and I didn’t have to have the anti-d injections. The baby was still tested after she was born and I was told that like the rest of us she’s was o-.
