The country's Covid-19 testing system has a maximum of one false positive for every 500 tests carried out, according to the Director of the National Virus Reference Laboratory.

The laboratory, which works to develop and deliver Covid-19 testing, played a vital role in the early detection of COVID-19 cases in Ireland.
