Dr. Colm Henry:

Briefly, the Deputy is absolutely right regarding the saliva test. It is a more acceptable and easier test, particularly for younger children, including those in preschool or primary school. A group of paediatricians and GPs has examined the issue and recommended it as a preferred test. The question is whether it is sensitive enough to be applied. That is being considered by the expert advisory group of NPHET chaired by my colleague, Dr. Cillian De Gascun. I expect the group to issue a decision on the matter next week.
