One of the biggest privately operated PCR and antigen testing operations in the country is today opening three new facilities to provide extra Covid testing capacity as the Omicron variant spreads.

RocDoc is opening the centres at Swords in Dublin, Shannon and Cork, which will be walk-in facilities only.

The new centres will see the creation of 120 jobs spread across the three locations and at RocDoc's headquarters in Ashbourne, in Co Meath.

The company already operates two facilities at Dublin airport and drive through facilities at Cork, Shannon and Knock irports.

RocDoc also worked with the Department of Transport earlier this year to provide testing for HGV drivers bound for France at a number of facilities nationwide.

It was also the first private testing company to provide the EU Digital Covid Certificate for international travel in July this year.

RocDoc's chief executive, David Rock, said that a lot of hard work has gone in to getting the services up and running in time for the busy Christmas period.

"We are hiring 120 new staff across the company to operate the new facilities, some of whom are already in place," the CEO said.

"We have been providing Covid-19 testing since August 2020, so we have a huge level of experience and expertise in providing accurate, efficient testing for patients in a highly safe and controlled environment," David Rock said.

"Our focus now is on continuing to provide a world-class service to all of our patients. For the past few weeks, we have been extensively testing our systems and procedures to ensure everything operates seamlessly from today," he added.
