I have to fill in a medical details thing for dd for a club she does and the form asks for her blood type. I am O+ as is DH, so my almost certainly idiotic question is will DD definitely be O+ as well?

I don't have a record that I can think of that shows her blood type and I am buggered if I am going to get her stuck with a needle to find out! As you can probably tell, I didn't do biology at GCSE and am therefore not sure what the rules are...!

Any knowledgeable types around that can reassure me?

why in the name of god do they need to know what blood type she is ????

just put unknown!

There is no earthly reason for them to know her blood type so just put 'not known'.

I have no idea what blood type my dc are. You don't get given this info. I asked what my own blood type was once and was told it wasn't info I was allowed. Found out when I was pregnant...

DH's parents, DH and two of his siblings all have the same blood type. His brother has a completely different one.

Yes definitely O+. We are a family of O+s too.

It's a martial art - I suppose there's the chance they might need to know (probably for far more advanced members who play with sharp thing occasionally).

Will go with unknown but would still quite like to know the answer!

We had to let my so 's nursery know in case there is an accident then it helps the doctors if they know his blood type I guess.

Oops cross post. Thanks greenleaf!

What type of club is she joining FGS?
I never knew my blood group until I was pregnant at the age of 30. I would not have a clue what blood group either of my DCs are (and they are 16 & 18)
I would put "not known". The hospital will find out soon enough if they need to.

I think she should be O but might be negative. Tis a crock of shift, in an emergency flying squad (universal donor) blood can be given. It takes a lab maximum of 10mins to issue type specific blood, whydo they needd to know

No, not definitely O+. She will most likely be type O but could be rhesus negative even though both parents are positive as rhesus negative is a recessive gene.

It's very important if she is rhesus neg that she doesn't get positive blood in her bloodstream as this will create anti-rhesus D antibodies which would cause rhesus complications in the future if she has children.

What sort of activity is it where they need to know blood group? (nosey) Sounds dangerous! Even GD's medical armband for cross-country riding doesn't have blood group recorded.

They wouldn't rely on this info anyway, the hosp would do blood typing. OTT way way OTT IMO.

Is this a blood donor club?

Put: Unknown. They'll figure it out quickly enough if needed.

Like I said, it's just part of the details on the licence she has. She has been a member for a while but I have only just realised the medical but wasn't filled in web I went to renew it. The licence covers all grades so I can see that an adult doing more advanced stuff and therefore possibly being more likely to be injured may find the section useful.

Hopefully she'll never end up being hospitalised because of it but it's useful to know how quickly they can type blood if needed.

But in emergency situations they give o neg as its universal. My DH is o neg & the vampires blood service hound him!

Sorry, it's taekwondo. The licence is the standard IMA licence.

I will put unknown just to be on the safe side!

Blood group should be O but as PP said her Rhesus type could be positive or negative. Both my parents are Rhesus positive and I'm negative as they must carry the recessive negative gene.
If in doubt O neg is used anyway.

They still don't need to know.

An emergency department would give O Neg to any trauma victim and a patient's own blood can be typed and cross matched within minutes. They wouldn't rely on a patient or their relative/carer stating what blood type someone was.

Thank you all . I have no idea about the positive/negative blood group rules so will err on the side of caution and hope they never need to know

as you are both O then she will be O as well. If you were different blood groups then it would be more complicated with a variety of possible groups for her to be. She could be rhesus positive or negative.

I only found out my blood group when I gave blood, same for dh. I have no idea what blood groups dd and ds are. I am B- and dh is A+ so they could be A, B, AB or O (they are both rhesus positive as I had anti-d after both births)

So if both parents are o, a child has to be o?

ILs are both B. DH, SIL and BIL are B. Other BIL is A.

I know bog all about blood types.

Ha, have just found an online tutorial with 'potential calculator' on it.

I used this to work it out

I only know my blood type from being a blood donor, DH knows his because he was on warfarin for a while.

I suspect I will continue to be confused by the rules (and eye colour rules)!

if they are both B then the children would either be B or O (not A)
