Figures show thousands of Scots have signed up as blood donors after an awareness campaign was launched last year to increase the nation's blood supply.
An additional 10,000 people are now blood donors in Scotland and health chiefs hope to build on this with a similar increase in the year ahead.
The release of the latest data coincides with the start of Blood Donor Week 2009, and the Scottish National Blood Transfusion Service (SNBTS) is using the event to launch a month of activity throughout June dedicated to increasing awareness.
Dr Moira Carter, national donor services manager with SNBTS, said: "This is hard evidence that the Scottish public has taken our message to heart.
"To keep up with demand, we need to repeat our success in the year ahead and add another ten thousand donors by June 2010."
She is urging people "who have never got round" to donating blood to sign up and help increase supplies, particularly over the summer months when supplies traditionally reduce by 20%.
Television and radio advertising campaigns will be shown throughout June as well as the first ever Give Blood campaign on YouTube.
