The Irish Kidney Association is urging people to carry Organ Donor cards as the organisations awareness week gets underway today.
The group says a record number of organ transplants were carried out last year - 294 organs were transplanted in 2013 through living and deceased organ donation.
Pat O'Sullivan from Mallow, Co. Cork, is waiting for a kidney transplant since 2012.
He explains that an organ transplant would "make a massive difference" to him.
