Your blood test results will determine your blood type (A, B, AB, or O) and your Rh factor, either positive or negative (for example, A+ or A−).
This test is especially useful for anyone who may need a blood transfusion (approximately 2.5 million units of blood are used for transfusions in the UK each year), those planning to donate blood, and women who are pregnant or considering pregnancy.
No phlebotomy fee is required for this test.
A blood group and antibody test (also known as ABO typing) determines your blood type and Rh factor in your red blood cells by taking a sample of your blood and combining it with specific antibodies (proteins produced by your immune system to protect your body from infection and disease) that target A and B blood.
The sample is then examined to see if your blood cells clump together. If they do, it means your blood reacted with one of the antibodies.
There are four major blood groups (A, B, AB, and O) and eight different blood types (A+, A-, B+, B-, AB+, AB-, O+, and O-). Group A has only the A antigen on red cells and the B antibody in the plasma. Group B is the opposite, with only the B antigen on red cells and the A antibody in the plasma.
Group AB has both A and B antigens on red cells but neither A nor B antibodies in the plasma. Group O has neither A nor B antigens on red cells but both A and B antibodies in the plasma. AB- is the rarest of the eight main blood types, with only 0.50% of the world’s population having it. The most common blood group in the UK is O+.
Babies get their blood type and Rh factor from their parents. A baby may have the blood type and Rh factor of either parent, or a combination of both parents. That is why siblings do not necessarily have the same blood type, even though they have the same parents.

A needle is inserted into a vein in your arm to collect a small amount of blood. You may feel a mild pricking sensation, but the procedure typically lasts only a few minutes.
