The Transport Minister says the planned Cabinet memo on subsidising the cost of antigen tests has been delayed because more detail is needed.
Health Minister Stephen Donnelly was due to bring the proposals to his Government colleagues this morning.
The subsidised tests will be available in pharmacies, with the Government rebating a portion of the cost to reduce the price of an antigen test to €2-3.
Minister Eamon Ryan says they need to find the right approach.
"It needs more detail, it needs more precision and we'd prefer to give it time and get it right.
"There are half a million tests that have gone out and people are using them - the critical thing is that they use them in the right way."
