NHS Blood and Transplant (NHSBT) has issued its first-ever amber alert as blood supplies dropped to a critically low level.
Hospitals have been told to implement plans to protect their stocks, meaning non-urgent operations requiring blood could be postponed to ensure they are prioritised for patients who need them most. A spokeswoman for NHSBT said current overall blood stocks in the NHS stand at 3.1 days but levels of O type blood have fallen to below two days.
O negative blood is the universal blood type which can be given to everyone. Around one in seven people have O negative blood.
