People in Kendal are being asked to register as blood donors.
The NHS has launched a Spring drive for donors.
It says it has blood donation sessions on Monday as well as the 14th of April at the Castle Green Hotel.
Amanda Eccles, Senior Marketing Coordinator at NHSBT, said: “Blood stocks are currently good, but it is vital that new donors in Kendal continue to register and make their first appointments to give blood to replace those who are unable to do so any more.
“O negative is rare, and is especially needed because it can be given to people of any blood group in an emergency. We are also particularly looking for new donors from black and Asian communities, as well as those who are A negative and B negative.
“It is also important that donors who are unable to keep their booked appointment please cancel them as soon as possible so we can reallocate the slot to someone else.”
To donate blood for the first time you need to be aged between 17 and 66. To register and to book an appointment call the Donor Line on 0300 123 23 23 or visit www.blood.co.uk
