The number of blood donations in Ireland decreased by almost 1,000 last year, with Storm Emma and the Beast from the East being blamed for the drop, as the storms results in the cancellation of clinics.
The Irish Blood Transfusion Service collected almost 126-thousand donations in 2018.
The service needs 3,000 blood donations every week to meet demand.
While the annual report shows an increase in the number of first-time donors last year, the number of donors in the 18-24 age category is low, and they're hoping for an improvement in these figures in 2019.
The Minister for Health Simon Harris is urging blood donors, and those who would like to donate, to visit their local clinic and give blood.
In Mayo this week, a blood donation clinic will be held at the McWilliam Park Hotel in Claremorris on Tuesday and Wednesday evenings from 5-8.30pm.
