The Irish Patients' Association says health officials need to urgently investigate why so many people aren't turning up for their Covid-19 tests.
Yesterday the HSE said up to a quarter of appointments at some of its centres weren't being kept.
95 more people were reported to have tested positive for the virus yesterday, with no deaths recorded.
Stephen McMahon from the Irish Patients' Association says all the no-shows could add up to scores of missed cases.
