Rachel Warden was 11 when she died of a brain haemorrhage last June.

She had decided at the age of seven that she wanted to donate her organs after her grandfather had a life-saving kidney transplant.

Rachel’s kidneys, pancreas and liver were transplanted, saving three lives.

Her parents, Sandra and Craig, and brother David were at Clydebank High School yesterday for the launch of a teaching pack about organ donations.

The family, from Clydebank, said that ensuring Rachel’s organs were donated had given them some comfort.

Mrs Warden, 45, a nursing assistant, said: “Her death was a total shock because she was fit and healthy. At the age of seven she made us promise that if anything happened to her she wanted her organs donated. That was the kind of girl she was, she wanted to help others.

“It means that something positive has come out of such a tragedy.”

Mr Warden, 44, a policeman, said: “It gives comfort to know she has helped other people live on and saved lives. She paid the ultimate price but she has helped others.”

David, 14, is a pupil at Clydebank High, which Rachel would also have attended.

The Wardens feature in a video which accompanies the teaching pack along with two other families who gave or received organs.

It is aimed at S2-S6 pupils and provides teachers with lesson plans and resources covering the science behind transplants and organ donation to give young people enough material to help them make informed, educated choices about the issue.

One of the other families in the video is that of Aaron Gray, now 13, from Peebles, who received a small-bowel and liver transplant when he was three years old.

He needed the transplants because of a post-operative infection after heart surgery which destroyed his bowel.

He then developed liver disease.

His mother Catriona, 45, spoke of her gratitude to the donor who transformed her son’s life.

She said: “They are my heroes, it is such a selfless act.”

The pack is being distributed to all Scottish secondary schools.

Health Secretary Nicola Sturgeon said: “It is important young people throughout Scotland learn about the realities of organ donation.”
