The HSE says people tested for Covid 19 should get a result within 48 hours by the middle of this month.
It's aiming to ramp up testing to 100 thousand a week from the 18th of May.
There's been criticism after some people had to wait weeks for a test result in the past.
CEO of the HSE Paul Reid says they're aiming to improve that:
"During May, and indeed on the 18th of May, we hope to maximise that now to about 48 hours from the time the swab test is taken to the delivery of the result.
"It'll be about maximum three days overall from the time a person contacts us to the time of the result, that's the plan."
