A Tayside woman has become the 50,000th volunteer to offer their support to a unique medical research project.
SHARE (Scottish Health Research Register) aims to make it easier for researchers in Scotland to carry out ground-breaking medical studies.
It uses blood left over from testing to help improve treatments for diseases such as cancer, diabetes and asthma.
Every day in Scotland around 70,000 samples of blood are discarded after routine clinical testing, but researchers are asking the public to allow them access to that spare blood.
Evelyn Hood, 78, from Ruthven, became the 50,000th person to volunteer for the register.
She said: “I have seen family members suffer with serious illness.
“If by doing something as simple as this I can give a help to research that might give us better diagnosis and earlier and improved treatments for diseases then that can only be a good thing.
“I have blood taken two or three times a year and it seems a waste to have the spare blood thrown away when it could be put to good use.”
