BLOOD donor sessions in Morpeth and Ponteland will be held in the coming weeks.
NHS Blood and Transplant hopes to boost blood stocks to 30 per cent above the usual levels before the start of the Olympics.
The increase is needed because of the anticipated high numbers of visitors to the UK.
Blood is used when women suffer complications during childbirth, to help premature babies, replace blood lost in surgery and to treat patients with cancer and blood diseases.
Anyone wishing to donate for the first time should be aged between 17 and 65 and be in general good health.
Those who have donated blood before can start again up to their 70th birthday and there is no upper age limit for people who have donated in the last two years.
A donor session will take place at Ponteland Memorial Hall in Darras Road on Thursday, June 21, from 1.45pm to 4pm, and from 4.45pm to 7pm.
There will be one at Morpeth in Storey Park Community Centre on Friday, June 29, from 1.30pm to 4pm, and from 4.45pm to 7pm.
