Among them was Simon Lee, from Applecross, who has donated more than 350 times, helping to save over a thousand lives.
Simon, who donates either plasma or platelets every fortnight, started donating after an accident resulted in him needing blood.
He had previously volunteered as a driver for the blood service, transferring people to and from work to donate blood.

READ NOW‘I started donating blood after I needed it following an accident,’ he said.
‘I thought it would be a good idea to help someone else.’
The week recognised the contributions of Australia’s 600,000 voluntary donors who together give more than 1.35 million blood donations every year.
Blood Service spokeswoman Jessica Willet said one in three Australians would need donated blood in their lifetime, but only one in 30 actually donated.
‘You never know when you or someone you love will need blood and there’s no better way to ensure it’s there than to become a blood donor,’ she said.
‘It only takes an hour of your time and every blood donation can help save up to three lives.
‘Pregnant mums, their babies, people undergoing emergency surgery, road trauma victims and those with certain blood conditions all rely on blood products to keep them alive.’
