Hospitals in Lancashire and Cumbria are trialling using drones to transport NHS medical samples.
Flying drones will cut delivery times between hospitals by more than an hour and speed up pathology results, the University Hospitals of Morecambe Bay NHS Foundation Trust (UHMBT) said.
Electrically-charged drones will slash the trust’s carbon footprint, it added.
Phil Woodford from UHMBT said the £1.4m project will cut out traffic delays and pollution.
It is part of the government’s Future Flight Challenge to develop greener ways of flying.
