The HSE has suspended walk-in Covid-19 testing at all centres across the country.
The health service says the decision has been taken to “reduce queues” after demand increased by 35 percent in the past 48 hours.
It says its online self-referrals system remains open, and is encouraging people to book through the portal at www.hse.ie instead.
Yesterday, walk in testing was suspended in Letterkenny, after the centre processed 750 tests on Monday.
