NHS Blood and Transplant needs donors with O negative and B negative blood to donate now as stocks are low due to a drop off in donations and an increase in demand for certain blood types.

The lack of O negative and B negative donors giving blood in the run up to the spring bank holiday has meant that stocks of these groups is in danger of falling below two days. So, NHS Blood and Transplant are asking anyone who knows they have these blood types but may have not donated before to give blood now.

However, there is a longer-term problem putting real pressure on these blood groups, particularly stocks of O negative, the ‘universal’ blood group often used when a patient’s blood type is not known, like in emergency situations.

To find out where you can give blood locally, to book an appointment or for more information call 0300 123 23 23 or visit www.blood.co.uk. Community donor sessions will take place at Farnham Maltings on June 21 and July 10.
