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 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.
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.
