The NHS is urgently appealing for donors of two blood groups to help rebuild stocks.

People with an O negative or B negative blood group in Enfield have been asked to donate blood after it was revealed that stocks are at their lowest level for four years.

NHS has now organised a session on Thursday, March 27 at Trent Park Golf Club in Bramley Road between 1.15pm and 7.30pm to help boost supplies.

Jon Latham, assistant director for marketing at NHS Blood and Transplant, said: “We constantly monitor donations and blood stocks for all blood groups throughout the year to ensure that we have enough blood to meet the demand of hospitals and patients, and have adequate contingency stocks. 

“Stocks of O negative and B negative are lower than we would like them to be and we are asking both O negative and B negative blood donors in particular.”

O negative is typically known as the ‘universal donor’ and approximately seven per cent of the UK has this blood group.

B negative is rarer, accounting for only two per cent of the UK’s population.
