THE parents of a four year old boy who is suffering from a blood cell deficiency are to take their appeal for a life-saving bone marrow transplant to shoppers.

Diane and Derek Lambert's son Calum, who was diagnosed with Aplastic Anaemia in December 2013, are to take part in a recruitment drive at the Post Office in The Centre shopping mall in Livingston, West Lothian, on Saturday.

The family are the latest to appeal to potential donors to sign up to the Anthony Nolan register. Last week, Fiona Hart, of Islay, revealed she had been separated from her children since Christmas as she is Glasgow for EBV lymphoma T4 killer cell, a rare form of blood cancer.

Mrs Lambert, of Livingston, said: "We were totally devastated when Calum was diagnosed and doctors told us that Calum needed a bone marrow transplant to survive.

"Our world was turned upside down that day, having no idea what the future would hold for our beautiful wee boy."

Blood cancer charity Anthony Nolan uses its register to match potential bone marrow donors to blood cancer patients in desperate need of a bone marrow transplant.

Although there are over 500,000 people already on the register, more lifesavers, especially young men, are needed. However, less than 60 per cent of patients in need of a bone marrow transplant can find a perfect match.

Staff and volunteers will be on hand on hand to talk potential donors through the details of joining the register, a simple process, and provide a saliva sample.
