The Irish Blood Transfusion Service is appealing to people to give blood as the current warm weather has seen stocks fall sharply.
They’re asking for 2,800 individuals to donate their blood this week.
According to the Chief Executive of the Irish Blood Transfusion Service Andrew Kelly donations fell by 26% at some clinics across the country last week.
Mr Kelly said while there is currently a four-day supply of blood, they would like to have seven days in the bank.
Summertime always presents challenges for the IBTS service and it is expecting a further fall in donations with exams and the Euro 2012 championships coming up.
Chief Executive Andrew Kelly is urging donors to make a special effort to give blood over the coming weeks.
