Dr. Kevin Kelleher:

I will say a few words and either Dr. Doherty or Dr. Cuddihy will add to it. We recognise that this is a major issue for us. There is a difference between how many people take the test on day zero and day seven. Some of that may be a consequence of the test itself, but it is an issue we need to address. Dr. Doherty has been doing some work in this regard.
