The Department. The only validated test recognised in Ireland is the PCR test, unless something has happened since we came into this committee room. The PCR test is the gold standard.

My understanding is that if people travel from another EU member state to Ireland, they will have to take a test that is recognised within that member state and certified by a credible entity. Many member states will use the PCR test. Each member state is working on its own approach to this matter.
