Group AB negative blood is needed for the manufacture of plasma - a rich 'soup' of essential proteins - plasma is separated from red blood cells and frozen when fresh. Less than 1% of the donor population possess AB negative blood.
Many people require blood, whether it's used for planned operations, in an emergency or for people suffering from conditions which require regular blood transfusions such as thalassaemia, leukaemia and those undergoing chemotherapy for cancer. If they have a rare blood group, we do sometimes struggle to get a perfect match for them.
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.
