The Irish Blood Transfusion Service has only three days' supply of blood in the country
Officials are calling for a "special effort" from donors to restore blood supplies around the country.
The Irish Blood Transfusion Service says the national supply is now down to just three days.
It wants an extra 1,500 donations over the next three weeks to stabilise levels, particularly from 'O positive' and 'O negative' donors.
The drive aims to return to a seven-day supply.
