Blood Types

[annie0000]

Does anyone know how to work out the likely blood type of your child? Strange question I know, but my son was admitted to hospital at the weekend as he was leaking blood and protein into his urine. Thankfully he is well on the mend now, but at one point they were talking about him possibly needing a transfusion. Luckily he didn't need it, but talking to my husband after the event, we both were thinking that had he needed blood, we would rather that we donated and he had ours than some random donors. That got us wondering about compatability. My husband has quite rare blood, I think it is AB negative, I know that I am O positive - very common. My son is now out of hospital, so I cannot ask what type he was (he did have blood tests) so I wondered if there is a way of finding out based on his parents blood types?

Ask you GP he should have your childs data including blood group.I think its a must that every parent should know their childs blood group,you never know when it has to be given.Hope you son is ok and on the way to a full recovery. best wishes g.

Thanks G - I will ask - we need to go back to hospital on Thursday anyway to check that he is still improving - he had post streptococcal glomerulonephritis as a rare complication of a sore that he had a few weeks ago. i took him to the docs on Thursday as he still was a bit under the weather - they said to give it another week, but that night I noticed that he had strange coloured urine - see the post a few down, and took him back on Friday - they sent him straight to hospital where we spent the weekend. He improved quickly and while he is still very pale, he was at school today and is getting his appetite back.

Well A and B are the dominant types, over O, and you have two alleles each. A and B are also jointly dominant. This means that if your blood type is A, your alleles could be either (A and O) or (A and A)
If your blood type is B, your alleles could be either (B and O) or (B and B)
If your blood is type AB your alleles will be A and B
If your blood type is O your alleles will be O and O

Therefore you must have OO and your husband has AB, so your child should therefore have AO or BO, therefore making him bloodgroup of either A or B

Thanks for you kindness garner - I guess you never stop worrying about them - my sons are 7 and 6 at the moment so a while until they are grown up!

Great answer Chazza - our hospital appointment is today, so I will ask and let you know if you are right - that's assuming that my husband is correct about his - I know mine as I donate fairly regularly - he tried to donate years ago - and was told that he had rare blood, unfortunately he gets really ill when he donates so had to give up - Giving for his son would have been the exception though.
