What does the O in blood type O positive mean?

Answer 1

I get what you mean...so I won't waste our time telling you about the antibodies and anitigens..."O" does't really stand for anything..

Answer 2

This is part of the ABO blood type group. There are 4 blood types involving the A and B antigens that have been recognized: A, B, AB and O. The letters indicate the type of antigen present on the red cell (erythrocyte). Type A has only the A antigen, type B has only the B antigen, Type AB has both antigens and type O has neither.

Antigens are proteins (agglutinogens) on the surface of the red cell that cause incompatibility reactions like with transfusions. There are many proteins on a red cell but the ones that are most likely to cause a problem are the A, B and Rh factor antigens.

Did you get your money's worth?

Note to "phil_m": Your answer was WAY too technical for this person.

Answer 3

The A antigen and the B antigen are derived from a common precursor known as the H antigen (or H substance). The H antigen is a glycosphingolipid (sphingolipid with carbohydrates linked to the ceramide moiety). Since it lacks N-acetylneuraminic acid (sialic acid) it is referred to as a globoside, not a ganglioside. In blood group O the H antigen remains unchanged and consists of a chain of galactose, N-acetylglucosamine, galactose, and fructose attached to the ceramide. H antigens can be changed into A or B antigens by enzymes coded by the blood group A or B genes. Type A has an extra N-acetyl galactosamine bonded to the galactose near the end, while type B has an extra galactose bonded to the galactose near the end.

Antibodies are not formed against the H antigen, except by those with the Bombay phenotype.

In secretors, ABH antigens are secreted by most mucous-producing cells of the body interfacing with the environment, including lung, skin, liver, pancreas, stomach, intestines, ovaries and prostate.

Answer 4

you've the most problem-free blood type contained in the U. S. (assuming that you're from the U. S.). you actually have an excellent "Rh aspect". Thia aspect is a chemical substance got here across on the floor of your pink blood corpuscles. about 80 5% of the U. S. inhabitants has this aspect. it isn't danger-free to transfuse your blood into someone that doesn't have the Rh aspect, even with the undeniable fact that someone with out the aspect (stated as Rh detrimental) can grant you with blood( on your case you could receive both type O Rh+ or Rh- blood). The Rh aspect became got here across through researchers utilising a RHesus monkey.

Answer 5

Blood group O individuals do not have either A or B antigens on the surface of their RBCs, but their blood serum contains IgM antibodies against both A and B antigens. Therefore, a group O individual can only receive blood from a group O individual, but they can donate blood to individuals of any ABO blood group (ie A, B, O or AB).

Answer 6

It means it has no antigens, so the red cells won't be destroyed by the blood if you give it to a non O person. Group O blood can be given to anyone.

Answer 7

it the way we divid differant blood types there is

A
B
AB
O

and they have a +/- factor the most common being o+ and the most rear A-

Answer 8

The O is the blood group. It isn't an initial for anything.

Answer 9

Wow Phil_m good answer I'm impressed - sounds like you've done some research in the field.

Answer 10

it means that your blood can be used in anyones body, nomater what blood type
