Blood Types

[biostudent84]

That is very strange. All my premed anatomy books(and by all i mean both of them ) clearly state: the rule that you can give 0 blood to anyone and that AB can get blood from anyone(providing Rh matches) only goes for one transfer, and maximum 500 mililtres of blood. If you repeatatly use 0 blood as universal donor for the same receiver, you might have the chance that the receiver fabricates anitzero aglutinines and, at a new transfusion, they will atack the rd blood cells of the donor. For large and repeated transfusions, izogroup transfusions are strongly recommended.
This book is written by one of the greatest doctors in my country, so i would look into this matter if i were you

Something doesn't sound right about that. Naturally, we try and give patients an exact match of blood whenever we can. But if we run out of blood, we would give far more than a pint of O blood if needed to keep the patient alive. ((500mL~1 pint))

Wow.. that's different from my country..(maybe mine is outdated)...
@Andrew:
What do you mean that the recepient will form antizero aglutinines???we know that O doesn't have any antigens whether A or B....it only has anti-A and anti-B. if you say that recepient must take different donor everytime doing transfussion then you mean that every O type blood is different then...(even in microscale)?

@victor
Check any recent anatomy book. People with O blood types have an aglutinogen on their red blood cells, it is called a 0 aglutinogen. It is an old, outdated information that they have none.

@Kyle
If you do not have anything else, you do what you can. Like i said, it is not a sure thing that the person will reject the blood, but there is a risk there. I don't know, i didn't rite the damned book!!!

[victor]

Ow...outdated again....I have to burn those outdated bio books in my cupboard...

[MrMistery]

Not really... Most of them come in handy since the livings things didn't change. But you need to buy newer books too to keep in touch with recent discoveries

With any blood transfusion, even if all fourteen blood types match, there is a risk of rejection. It happens.....

[victor]

Yup..and in case of that rejection..my sister always use a blank blood...doesn't have any antigens or antis.

[MrMistery]

How exactly can you get that kind of blood?
@Kyle
Agreed... But the risc is increased if the type doesn't match

[victor]

I call it blank blood because after they take it from the donor, they 'wash' it first (what I mean is not really washing, just seperate the O antigen from O typed blood) and then they transfuse it to her.
Actually she got a hereditary blood illness called thallasemia which made her body couldn't form any Hb..so they do transfussion only for the Hb..

[MrMistery]

How can they get rid of the O aglutinogen? It is located on the surface of the red blood cells

[victor]

I dunno...it's the doctors' homework..
ask b_d_41501 he shold know about this (or might be...or supposed to be)

[victor]

Hey, this is the fact...O type blood is the most in the world because O type blood is the ancestor of all blood types (referring to ABO type). all O type comes from Africa and when they travel to another continents, some of the gene get mutated and form A, B and AB. It's known that A type is more resistance to illness and B type is more resistance to cold weather.
