We know. Do you?

This National Blood Week we've been inspiring the country to get talking about blood types. Do you know yours? You can join the conversation by sharing your blood type on social media, using emojis  🅰 🅱 🆎 🅾 ➖ ➕ or by simply talking to a friend about blood donation.

One million new blood donors are needed over the next five years to ensure patients continue to receive the types of blood they need.

There's a particular need for Black African, Black Caribbean and younger donors, to ensure we can double the number of donors with the rarest blood types. This will enable better matched blood types for patients in the future and reduce health inequalities.

Help us to inspire others.

Please get involved and share your blood type on your social networks using blood type emojis 🅰 🅱 🆎 🅾 ➖ ➕ or download one of our new blood type Giphy stickers, adding #NationalBloodWeek and tag @givebloodnhs.

Find us on Instagram, Twitter and Facebook and share your favourite content.

If social media isn’t your thing, talk to friends, family and colleagues, start a conversation about blood types and encourage them to register to become blood donors at blood.co.uk.

Those who haven’t yet donated and therefore don’t know their blood type can also come along to our What’s Your Blood Type events to find out.

Come along, take your next step towards saving lives and share your blood type with pride!

We know. Do you?

So, what does your blood type say about you?

There are eight main blood types, some rarer than others.

Whether you are A, B, AB or O, patients need your blood. Some blood types are in higher demand than others and are needed more regularly, but please remember, every donation you make can save up to three lives.

O positive is the most common blood type. Around 35 per cent of blood donors have this blood type – that’s 1 in 3 blood donors.

O negative donors make up 13 per cent of the donor base and are often called the ‘universal donor’ because their blood can be given to people of any blood type in an emergency.

Around 30 per cent of blood donors have A positive blood.

1 in 13 blood donors is A negative.

Only 8 per cent of donors are B positive.

2 per cent of donors are B negative, making it one of the rarest blood types.

1 in 50 blood donors is AB positive, making it very rare.

AB negative is the rarest of the 8 main blood groups accounting for only 1 per cent of blood donors.

Blood types and personality

Some people think your blood type can tell you about your personality and temperament too. In Japan, it is widely believed that there is a link between human ABO blood types and personality traits.

"In this country a lot of people don’t know their blood type, whereas in Japan, many people live their lives based on it," says Martin Maley, a senior lecturer in biomedical sciences at the University of Sunderland and previously head of the NHS Blood and Transplant Red Cell Immunohaematology Laboratory in Newcastle.

O group: popular, confident and creative

A group: calm, shy and excellent listeners

B group: ambitious and driven to achieve

AB group: stand out from the crowd, logical and determined

Whatever your blood type, your blood is very important! Book your next appointment to save up to three lives in just one hour.
