NHS Blood and Transplant is appealing for volunteers to attend blood donor sessions to help meet the demand for blood from local hospitals.
Sessions are taking place on Saturday, May 10, at the Catholic Guild Hall, Tape Street, Cheadle, from 9.30am to 12pm and 1.30pm to 4pm.
NHS Blood and Transplant needs people from all blood groups to donate, but O negative and B negative donors are particularly needed.
O negative or "universal" donors can help patients with a different blood group, vital in an emergency when there may not be time for an immediate blood grouping test.
B negative blood is also in demand.
In general, as long as you are fit and healthy, weigh over seven stone 12 lbs (50kg) and are aged between 17 and 66, up to 70 if you have given blood before, you should be able to give blood.
If you are over 70, you need to have given blood in the last two years to continue donating.
