Blood Type + Rh

A blood type test determines your ABO blood group and Rh factor. Knowing your blood type is essential for safe blood transfusions, organ transplants, and pregnancy planning.

Doctor's Assessment Included

Reference Ranges

No established reference range

A blood group is an inherited characteristic, not a measurement. The result is a type (A, B, AB or O, rhesus positive or negative); no reference value exists and no blood group is abnormal.

Reference ranges may vary between laboratories. When you order a test, a BIG-registered doctor assesses your personal results in context. For treatment decisions, discuss your results with your GP.

What It Measures

This test identifies the specific antigens present on the surface of your red blood cells, classifying your blood into one of the major groups (A, B, AB, or O) and determining whether the Rh (Rhesus) factor is present (positive) or absent (negative).

Why It Matters

Blood type compatibility is critical for safe blood transfusions and organ transplantation. During pregnancy, Rh incompatibility between mother and baby may lead to complications if not identified and managed. Knowing your blood type also supports emergency medical preparedness.

When to Test

Blood type testing is typically performed before surgery, blood transfusions, or organ donation. It is also routinely checked during pregnancy. Once determined, your blood type does not change and generally only needs to be tested once.

Lifestyle Tips

Carry a card or digital record of your blood type for emergencies. If you are Rh-negative and planning a pregnancy, discuss this with your healthcare provider. Consider becoming a blood donor, as certain blood types are in high demand.

Frequently Asked Questions

Can my blood type change over time?
No, your blood type is determined by your genes and remains the same throughout your life. In extremely rare cases, a bone marrow transplant may result in adopting the donor's blood type.
Why is Rh factor important during pregnancy?
If an Rh-negative mother carries an Rh-positive baby, her immune system may produce antibodies against the baby's blood cells. This can be managed with Rh immunoglobulin injections when identified early. Consult your healthcare provider for guidance.
