wrong blood type?

Question

I'm just curious. What happens if somebody is given the wrong blood type?

Answer 1

If you are given incompatible blood a series of events occurs that is known as a hemolytic transfusion reaction. It can be extremely serious and may lead to death. The naturally occurring antibodies in the recipient will bind to the antigens on the incompatible donor red cells leading to the breakdown of those cells aka in vivo hemolysis. The liver will then have to try to dispose of the broken down cells resulting in an increase of bilirubin and urobilinogen in the blood and spilling over into the urine. The pateint's blood pressure will start to drop resulting in tachycardia and possibly cardiac arrest...

Answer 2

You don't get HIV or AIDS - you only get those if the blood that's being put into you carries the HIV virus, and its nothing to do with blood type.

What does happen (assuming that you get given blood that your body recognises as "non-self") is that your white blood cells - your immune system - recognises the blood cells as being invaders into your system, and promptly attacks them as possibly disease-causing.

So your blood and the new blood basically clot. Which, depending on how much you received and where the clot forms, can do anything up to kill you (say, if the clot forms in a major artery or the heart, or bits break off the clot and reach the heart).

And of course, which blood types are safe for a person depends on both the antigens on your blood cells (whether you have A/B/both/neither and whether you're rhesus positive or negative - with O negative being the "universal donor")

Answer 3

AB can receive any "regular" blood (O, A, B, AB). O can receive none of them except O (they don't have the factors to handle the blood). Some people but not all can die. The Rh factor is also important, someone O- needs the negative or the blood isn't compatible.

There's a lot of work in this area, so there will be new innovations such as "artificial" blood that doesn't require typuing.

PS You only get HIV if one of the donors had HIV. It does NOT :"create" AIDS.

Answer 4

You should start by not wanting to get pregnant, just have sex everyday or every other day and don't think about getting pregnant, just have fun with your partner. Get more useful information and guides to get pregnant herehttps://tr.im/RoQ8Y
after sex-put a pillow under your butt or prop your feet up on the wall so your pelvis is tilted
eat healthy
back off caffiene
workout, even if its just a 20 minute walk a day, be active.

Answer 5

Type A RBCs contain "anti-B" antibodies and "A" antigens and type B RBCs contain "anti-A" antibodies and "B" antigens. So, as the previous poster mentioned, if you give "B" blood to a type A recipient, you will be introducing an antigen to which the recipient has antibodies, which can trigger an immune response. The universal donor, type O, does not contain the "A" or "B" antigens, so it will not cause this problem. Similarly, if you are type AB, you are a universal recipient, because your blood cells do not have "anti-A" or "anti-B" antibodies.

Answer 6

The blood is rejected and made useless.. and can kill you, you can't get AIDS or HIV from donor blood in the UK as it is screened to prevent people getting it.

Answer 7

depending on the amount, it can kill you, i believe. it's interesting to note that newborns can receive any blood type, and as they mature, they can accept all of the blood types they received (and were born with).

Answer 8

Not a lot your white blood cells will be busy for a while which will lower your immunity

Answer 9

depending on which blood type is compatible or uncompatible with yours, that is what will determine wat happens. if it is different, your body can become very sick because it will most likely reject it

Answer 10

They develop HIV/AIDS

Thats one way of getting it. If two different blood types mix you develop HIV, you need to get treatment. There are NO physical signs you have HIV, so it could well develop into AIDS [a more severe disease] this kills all of your "antibodies" which are the things that protect you from dying of colds etc. When you have a cold, your antibodies fight the disease, and get rid of any bug / disease in the body. Cimotherapy [sorry about the spelling], the treatment for cancer reduces antibodies, too. It reduces the cancer antibodies, but also yours, so its vital you get rest etc, and by drinking things such as 'actimel' increases the chance of survival for your good antibodies.

If you have AIDS your antibodies decrease so much that when you get a cold, your body can't fight it, so you dont die from AIDS, but a cold, however, AIDS is the cause of it.

For more information on 'AIDS/HIV' go on www.wikipedia.org and search "AIDS" or "HIV"

Its vital you regurlarly get check ups!

Also, when women are pregnant, blood from the mother and the baby NEVER mix, it stays slightly apart. If it mixes, this is mostly how miscarriages occur. So, you will often find that you have a different blood type from your mum, and you will probably have the same as your dads.
