Mr. Brendan Gleeson:

Yes. Their own laboratory is accredited for the purposes for which it is used. Again, this is about regulations that will state that if there is to be a test to challenge a result, it must be carried out at an approved laboratory and must use the technique provided for. Otherwise, there is chaos and a variety of techniques can be used and a variety of substances tested. The results one might get from blood and urine, for example, might be entirely different, so it is important that if one compares results, one does so on the same basis.
