Because your blood group is O RhD positive, you are especially important. Around 37% of the 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 83% of people.
So your blood can help 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.
You can give blood three times a year, so please be sure to keep up your outstanding work and donate every four months if you possibly can.
