Hi Roger, Thanks for the information about the test for pd. I heard something this week about this research before I returned from Sydney, but had no way to find out the exact information until now. I think that Australian doctors have a lot to be proud of in the research that they are engaged in especially those at Prince of Wales Research Center whose work I saw reported more than once on your ABC station while I was in Australia.
