BLOOD donors from two specific groups are being asked to come forward.
Those who are O negative, and B negative, should give, as the hot weather has resulted in a drop of blood donors.
Jon Latham, assistant director for marketing for NHS Blood and Transplant (NHSBT), said: ‘Stocks of blood for vulnerable blood groups are lower than we would like them to be. I’m asking blood donors with those two groups in particular, to walk in and donate now.
‘By doing so you can help us replenish vital stocks and ensure that we can continue to meet the needs of patients.’
NHSBT is responsible for collecting, testing, and delivering blood to hospitals.
It has revealed O negative donations are down 11 per cent on last year, and B negative donations are down 12 per cent.
First-time donors should be aged between 17-65, weighing at least 50 kg (7st 12lbs) and in general good health.
There is no upper age limit for donors who have donated in the past two years.
