O Positive Blood

O Positive Blood

Because your blood group is O RhD positive, you are especially important. Around 36% of the donor population share your group, but what makes you even more important is that, if necessary, your blood can be given to anyone who is RhD positive (regardless of their blood group) - and that's a staggering 79% of people.

So your blood can help almost eight out of every ten hospital patients, whether they're mothers and new-born babies, people being treated for cancer, or having planned operations like a hip replacement.

Female donors can give blood three times a year and male donors can give blood four times a year. So please be sure to keep up your outstanding work and donate regularly if you possibly can.
