I just hope that some where they actually come up with a policy and make it clear with in the Med Trade, case in point.
Up north we get tested for TB every fall, 2004 I had my book with me as I just got posted to Yellowknife and had come back from a tour so it was handy, did the PPD and the med techs said, you shouldn't hold on to that we will, what reason do I have to argue, I don't hold on to my med files so...
2006 New Med tech -new PPD (the one in 2005 was by the same crew in 2004) asked for our Yellow books, informed that they held them after a few disagreeing views on the matter they pulled our med docs and found our yellow books- apparently they weren't suppose to be they, we were told they had to be prior. As a foot note although I have only been doing this for about 20 years it has been hit or miss on where they go or who holds them in my time in.
