Blood transfusion...how does the dna of the other person not affect you?

There are two things to consider:\n\n  In a blood transfusion, they don't always give you all the components of blood (the red blood cells, the platelets, the plasma, etc.).  In a normal transfusion, the person ONLY gets red blood cells and the plasma.  Neither of these has DNA...  Red blood cells do not have have a nucleus at all; that is why your body is constantly making new ones (and why you can keep giving blood without eventually "running out").  The plasma is just "fluid", so there's no nucleus there, either.  So, just getting a normal transfusion will not expose you to DNA.\n  Second, IF DNA somehow got in, I don't think there would be enough of it to cause any problem.  It would only be a small amount (because blood is largely plasma and cells) and, so, any DNA would not be common and, thus, probably easily handled by your body's defense system.  \n  Besides, DNA would only be a problem if it was in a cell where it can be translated and transcribed into gene products (proteins, etc.).  If it was just "floating around" in your blood, product wouldn't be made from it.  Also, the DNA would probably degrade fairly quickly.  DNA is sturdy, but blood has plenty of enzymes and different pHs that would most likely damage the DNA in some way.\n  So, that's my answer.  the second part was a little bit speculation, but I believe I'm right (I KNOW I'm right about the first part).

Blood group is highly related to genetics. It is possible to have an O child even if both parents are not O.\n\nIf the parent's are both a heterozygote, then there is 1:3 chance that the child get an O blood group. However, if at least one of the parents are homozygot, then it's impossible.\n\nAbouth the two Rh+ become Rh-. It's also possible, since it's basically the same as the ABO blood group, if the Rh+ parents are heterozygots then it's possible to have a child of Rh-. \n\nSo:   \nBO +- >< BO +-\ncan have a \nOO --\nchild.

The most interesting question of the day, so I had to do some research. While I thought it was impossible because of the antigens present in blood types, this article seems to indicate that it can be done. That sure will relieve blood supply issues.

That is weird, my friend and I were discussing that yesterday. She had been to the doc and he said that the blood bank loves her blood, she is 0 neg. too. She told me that anyone can get her blood, but she could only have 0 neg. herself. I never knew that! I have no idea what type I am, but I will find out now. Thanks for reminding me to do that!

The baby makes its own blood. It comes neither from the father or the mother. While it is in the womb, its own blood circulates through the cord and receives nutrients from the mother but the baby's blood and the mother's are separate and never normally mix. \n\nSince the baby receives genes from both the mother and the father, the type of blood is influenced by that.

Someone with A- blood can donate to a person with A+ blood type.  Both of your blood types are A (no problem there) and your blood is lacking the Rh factor (hence your blood is A-).  Since you have the same blood type and you are lacking the Rh factor you have no problem donating to a person with A+ blood type.\n\nAnd to correct wiserangel O- is the universal donor, O+ is the universal reciever.

A Red Cross study reported in 1989 that the risk was one in 153,000.\n\nCurrent estimates are that fewer than 1 in 1,900,000 blood components is capable of transmitting HIV.\n\nTherefore, the risk is very very very small.  You should be more worried about other Transfusion-Transmitted dieses.

No there is no link.  Every non-scientific person seems to think that blood type is a major genetic factor that differentiates people.  The truth is, your blood type is just one of tens of thousands on minor genetic details that make you different from the person next to you.  I'm not saying blood type isn't important, it is very important when it comes down to blood transfusions, and to a lesser degree for organ donation.  This is important because an immune system tends to react with the "unknown" blood cells when used in a blood transfusion.  These cells may have minor changes to the sugar molecules attached to proteins in the red blood cell.  This makes them "foreign" and can cause severe blood clotting and death.\n   There are whole other sets of genes that will determine which types of foods you shouldn't each (allergic reactions) and need to each extra of (vitamin or other dietary deficiencies), but these are completely unrelated to your blood type.

http://gslc.genetics.utah.edu/units/basics/blood/types.cfm\n this explains both questions. at the bottom of the page there is a link to "what is a blood transfusion" it tells you how it works too.

4 out my 5 sons have their dad's blood type while only one has mine. It really doezsn't matter though......\nWiserangel is nuts. A child HAS to have the blood type of one or the other parent. Can't just have one made up..........

It is not possible to pass on a food or preservative allergy to someone else by donating blood.  Such reactions are caused by immuno globulins which are removed from the blood before it is stored by the blood bank.  It is very noble to give blood - it is certainly needed - and I hope that you will continue the practice.

i hope your talking about an intimate act with someone you wish to be VERY close with, and not the general public.  a little bit of blood is not harmful, unless the "donor" is ill.  small cuts in areas not seen by the general public is a good idea.  no need for others to know about such practices.

because if you are in need of blood and the Dr's give you the wrong type it can kill you your body attacks it because it is totaly forign.  So they type the donor and the recipient.  If you are wondering why you have had your blood typed more than once it is because it did not make it into your file and the can not take your word for it because it cool kill someone

Without pasting a book in here from another webpage and without adding info that you didn't ask for: you can accept A and O, anything other than that will kill you. The existing blood will attack the new blood.

That would be a violation of HIPPA, which provides protection for our medical records. I do believe that law enforcement officials can search for DNA matches of those who have given samples, but civilians cannot and, I believe, should not be able to. Your DNA is similar to those you are related to: your mother, father, siblings. Humans also share basic DNA sequences.

If the blood of the primate is very similar to your blood. Otherwise, your body may not cope with it, and you will die, or your body rejects it, and you will die. Unless you transfuse it out of you, but that leaves you with no blood again.

The children would have bloodtype A or bloodtype B.\n\nThe "O" which they get from one parent is merely an absence of the information necessary to have specific antibodies against other bloodtypes.
