Professor Philip Nolan:

In fact, they are not recommended for such use. Before one goes off and invests in designing pilots to be added to the highly effective regime that we already have, one has to consider how likely it is that there will be a positive finding.

It is not possible to say how long it would take until someone sits down and sets out the use case through which these tests would be validated. To give a simple sense of the matter along the lines that Professor Keogan mentioned, if we go out tomorrow and administer tests to 100,000 people in Ireland, we are likely to find 100 to 200 infections. We would not be testing 100,000, but 100 to 200 people. As Dr. Holohan stated, doing these pilots is very challenging and takes time, and before one embarks upon a pilot, one must judge whether there is a likelihood that it will-----
