Blood groups play a crucial role in our bodies and are essential in medical procedures such as blood transfusions, organ donations and pregnancies. Yet many people do not know what blood group they have and what its implications are. In this comprehensive guide, we answer the most frequently asked questions about blood groups and explain how you can easily find out your blood type.
What is a blood group?
A blood group is a classification of blood based on the presence of certain antigens on red blood cells. These antigens determine how your body reacts to transfused blood. The ABO system and Rhesus factor (Rh) are the main systems used to classify blood groups.
What blood groups are there?
There are four main types of blood groups in the ABO blood group system:
- Blood group A – Contains antigen A and anti-B antibodies.
- Blood group B – Contains antigen B and anti-A antibodies.
- Blood type AB – Contains both antigen A and B and has no antibodies to other blood groups. This makes people with blood type AB universal recipients.
- Blood type O – Contains no antigens, but does contain both anti-A and anti-B antibodies. This makes people with blood type O universal donors.
Find out which blood group is most common and which is rarest in this overview.
What is the rhesus factor?
In addition to the ABO blood groups, blood is also classified according to the Rhesus factor (Rh).
- Rh-positive (Rh+) means that the D antigen is present on red blood cells.
- Rh-negative (Rh-) means that the D antigen is missing.
The combination of the ABO system and the rhesus factor results in eight different blood groups, such as A+, A-, B+, B-, AB+, AB-, O+ and O-.

How is your blood type determined?
Your blood type is genetically determined and inherited from your parents. Each individual inherits one ABO gene from the mother and one from the father, allowing combinations such as:
- Parents with blood type A and B can have a child with A, B, AB or O.
- Two parents with blood type O will always have a child with blood type O.
- Rhesus factor is passed on in the same way: a parent with Rh+ can have either an Rh+ or Rh- child, depending on genetic makeup.

How can you test your blood type?
There are several ways to find out your blood type:
- Blood test at the GP – Your doctor may perform a blood test to determine your blood group.
- Blood donation – When you donate blood, your blood type is automatically tested and recorded.
- Medical documents – Your blood type may be listed on your donor card, medical record or vaccination card.
- Blood group self-test – With a home blood group test, like the one from The Tester, you can easily and reliably determine your blood group within 40 seconds.

Why is it important to know your blood group?
Knowing your blood type can be vital in many situations:
- Blood transfusions – During a blood transfusion, it is crucial that you receive compatible blood to avoid dangerous immune reactions.
- Organ donations – Organ transplants require compatible blood groups.
- Pregnancy – Rh factor plays an important role in pregnancies. An Rh-negative mother can produce antibodies against an Rh-positive baby, which can cause medical complications.
- Medical emergencies – In an emergency situation, knowing your blood type can be life-saving.

Which blood group is most common?
The most common blood group worldwide is O-positive (O+), followed by A+. About 37% of the world’s population has O+, while 27% have A+.

Which blood group is the rarest?
The rarest blood group is AB-negative (AB-), which less than 1% of the population has.
Read here which blood groups are the rarest.
Which blood group is universal donor?
Blood type O-negative (O-) is the universal donor, meaning that people with any blood type can receive O- blood without immune reactions. This makes O- extremely important for emergency cases.
Find out more about the universal donor and why O- is so important.
Does blood type affect health?
Research suggests that blood groups may be linked to certain health risks:
- People with blood type O have a lower risk of cardiovascular disease.
- People with blood type A may have a higher susceptibility to certain infections.
- People with blood group AB are at increased risk of blood clotting problems.
While blood groups can have some impact on health, lifestyle is much more important for your overall well-being.

Your blood type plays a role in your health and medical treatments, but many people do not know their blood type. Are you prepared for an emergency?
