When it comes to blood types, there are four major groups: A, B, AB, and O. But which one is the most common in the UK?

According to the NHS Blood and Transplant, the most common blood group in the UK is O positive. Approximately 35% of the population has this blood type. O positive is often referred to as the "universal donor" because it can be transfused to patients with any blood type. This makes it a crucial blood type for emergency situations.

Following closely behind O positive is A positive, which makes up about 30% of the UK population. B positive is the third most common blood group, with around 9% of the population having this type. AB positive is the rarest blood group in the UK, making up only about 4% of the population.

Knowing your blood type is important for a variety of reasons. In addition to being able to donate blood to those in need, understanding your blood type can also be important for your own health. Certain blood types are more prone to certain health conditions, so being aware of your blood type can help you take preventative measures.

If you are unsure of your blood type, you can get tested through your doctor or through a blood donation center. It's a quick and simple process that can provide you with valuable information about your health.

Overall, O positive is the most common blood group in the UK, followed by A positive, B positive, and AB positive. Knowing your blood type and being willing to donate can help save lives and make a difference in your community.
