The HSE has apologised to people who are waiting for Coronavirus test results.
Some people have been waiting as long as a week to get the results of their tests.
Not all testing centres are open across the country today, but the HSE says enough are available to deal with demand.
Assistant Secretary at the Department of the Taoiseach Liz Canavan says the HSE is trying to improve turnaround.
"This week the HSE public analysis laboratory in Cherry Orchard and a Department of Agriculture laboratory have come online, bringing additional capacity in the laboratory space.
"The HSE has asked us to apologise to all those awaiting test results, and to assure the public they're making every endeavour to improve turnaround times with the current International constraints."
