EXISTING donors of all blood groups are being asked to donate to Gloucester Blood Donor Centre.

Due to the recent freezing weather and snow, many people have not been able to donate.

The bad weather has also led to some sessions being cancelled.

Nationally, around 6-7,000 donations have been missed, more than one days worth of collection.

A+ and A- platelet donors who have booked appointments are being asked to do all they can to keep them, if safe and possible to do so.

Any platelet donors who don't have an appointment are being urged to come to a fixed donor centre and give as soon as they are able.
