Blood antibodies and what they mean?

[Mothernature]

I had a blood type test. My blood was + and antibodies were negative.

What are anti-bodies and what does a negative test mean?

The differences in human blood are due to the presence or absence of certain protein molecules called antigens and antibodies. The antigens are located on the surface of the red blood cells and the antibodies are in the blood plasma. Individuals have different types and combinations of these molecules. The blood group you belong to depends on what you have inherited from your parents.



Blood group A
If you belong to the blood group A, you have A antigens on the surface of your red blood cells and B antibodies in your blood plasma.



Blood group B
If you belong to the blood group B, you have B antigens on the surface of your red blood cells and A antibodies in your blood plasma.

Blood group AB
If you belong to the blood group AB, you have both A and B antigens on the surface of your red blood cells and no A or B antibodies at all in your blood plasma.

Blood group 0
If you belong to the blood group 0 (null), you have neither A or B antigens on the surface of your red blood cells but you have both A and B antibodies in your blood plasma.

Hope this is what you meant.

a negative test is normal. antibodies are something that your body makes naturally and if you have them it makes it harder for your blood to be "typed" for a blood transfusion. it just means that the blood bank would have to do additional testing to match your blood with the donor if you need a blood transfusion. they is nothing that you can do to get or avoid antibodies. so nothing is wrong.

do you have any other questions about this?

The US goes by ABO group and Rh +/-, but there are many more antibodies in the blood than these. Most people aren't tested for extra antibodies until it is time for transfusion.

If you have an antibody, the hospital may have trouble finding blood that is compatible. Since you don't have antibodies, you shouldn't have any problems.

I am O Pos Anti-P, but I only know this because I used to work in a blood bank.
