Blood types are divided into 4 main categories – type A, type B, type AB, and type O. The blood type is determined by the type of protein on the surface of the red blood cells. Type A blood has A proteins, type B has B proteins, type AB has both types, and type O has neither.

It is the presence of these proteins that determines what type of blood can be given in a blood transfusion – giving the wrong type can be life threatening – because a recipient’s immune system can react against the donated blood. Other than the A and B proteins, there is another protein called the Rhesus (Rh) antigen. A blood type can be Rh positive, or Rh negative.

This is particularly important to know during pregnancy as there may be a problem if the baby has a different rhesus status to the mother. The result will come in the following format: A RhD positive (A+) A RhD negative (A-) B RhD positive (B+) B RhD negative (B-) O RhD positive (O+) O RhD negative (O-) AB RhD positive (AB+) AB RhD negative (AB-) This test is also a requirement for most (very) extreme sports pursuits and prior to majority of operations. 1 Biomarker BLOOD TYPE - Blood Grouping and Subtyping Blood Test TURNAROUND TIME The turnaround time for this test is 5 working days
