The service is running appointment-only clinics since the start of the pandemic, and this will continue for the foreseeable future.
"Blood stocks this morning stand at 3 days across the main blood groups," said Barry Doyle who is IBTS' Operations Director.
"Bank holiday weekends are always difficult as our capacity to collect blood is reduced, the increased incidence of COVID-19 in the community as well as seasonal illness is having an adverse effect on donor attendance.
"Therefore we are asking donors to help us support the health service by making an appointment to give blood when they receive a text from us.
"The increased demand experienced during the summer and sustained into Autumn has had an impact on stock levels of all blood groups. COVID-19 continues to impact donor blood collections and our ability to maintain the blood supply has become increasingly difficult."
