Over eight-hundred people were tested for Covid-19 at a pop up centre in Athlone which ran for three days.
The HSE has confirmed that it will take a number of days to determine if any of those who were tested are positive for the Delta variant of Covid 1-9.
The Covid pop-up test centre at the former St Aloysius College in Athlone closed on Saturday afternoon with a total of 183 people getting swabbed.
The centre, which ran from Thursday morning until Saturday afternoon, tested a total of 844 people after the HSE issued an urgent appeal for people in the town to get tested following reports of a Delta Covid variant outbreak in the town.
The HSE says it will take some time to confirm any Delta cases which may emerge from the testing process.
Separately, the latest report from the health protection and surveillance reveals that Roscommon remains the county with the third highest 14-day Covid incidence rate after 82 cases between June 11th and 24th.
Westmeath recorded 97 cases in the same 14 day period with 51 in Cavan, 23 in Monaghan, 20 in Longford and 15 in Leitrim.
