This test identifies your ABO group and RhD status. The result can be relevant in pregnancy and when blood compatibility must be assessed.

Understanding the test
Also called Blood Type (ABO & Rh)
Blood grouping can be useful for maternity care or establishing a documented blood type. Tell the team about recent transfusions if these are relevant to the request.
The report identifies ABO group and the presence or absence of the RhD antigen.
Blood group is one piece of information used in pregnancy and transfusion planning.
Before your sample
No fast is necessary. Provide the requested identification details and mention any recent transfusion or stem cell transplant so the laboratory can assess the context.
The clinician takes blood from a vein into a tube that keeps it from clotting. The collection team sends the labelled specimen to the laboratory.

The report gives an ABO group and RhD status rather than a high or low value. Separate antibody screening answers a different compatibility question.

Keep the official record of your group. Ask the maternity or transfusion team whether a separate red cell antibody screen is needed for their purpose.
Patient questions
Transfusion services perform their own identification and compatibility checks. A previous blood group result is useful information but does not replace those safety procedures.
Your report gives two independent things written together: an ABO group (A, B, AB or O) and an Rh D factor, positive or negative, for example O positive or A negative. It is a category, not a level, so there is no normal or abnormal result and no group is better than another.
Yes. Donor cells circulating alongside your own can make the grouping reaction hard to read, so tell the team if you have had a transfusion in recent months. A bone marrow or stem cell transplant can change your group altogether, and the laboratory may need to handle the sample differently.
No. Your blood group shows whether your red cells carry the RhD marker. A separate red-cell antibody screen looks for antibodies that could affect the baby. Your maternity team uses both results to plan any prevention or follow-up you need.
