I'm going to let others speak to this, but I can say that in terms of some screening tools, Canadians are leaders. We have some work around the meconium, which is the first stool of babies when they're just born. It is important because it gives you an important indicator of whether or not the mother drank alcohol during the whole pregnancy. That came out of research, and it's a Canadian researcher. I don't remember the name, but it's somewhere in Ontario. There is hair analysis. There are all these new tools that will be extremely important, because they will validate the diagnosis in the future.
Maybe you could say a little bit more, Barbara.
