The Health Service (HSE) has suspended walk-in Covid-19 testing as demand has soared.
There has been a 35% increase in demand for testing over the previous 48 hours.
There was a three hour queue for a walk-in testing centre in Letterkenny, Donegal, which has one of the highest rates of the virus in the country.
The HSE said the public are being asked to book their test appointments online to avoid uneven usage with frequent variance between queues and quiet times.
New figures from the European Centre for Disease Control show Ireland now has the highest rate of Covid-19 in the EU/EAA area.
Over the past weekend, 9,500 people availed of the walk-in vaccination centres across the country, half of whom were in the 12-15 age cohort.
