The concept of a objective test for fatigue has been looked at for years so it will be interesting to see whether these blood tests are a breakthrough or just another attempt to crack this particular nut and it ends up going nowhere.
Whatever, I suspect that we are a heck of a long way off seeing the sort of legislation hinted at in the Guardian (e.g. 5 hours achieved sleep in a rolling 24) being enacted in the UK.
Should not such tests be applied to all NHS doctors so they don't go on working beyond their tiredness capacity? Should our politicians be tested so they don't make foolish decisions when too tired?
I wouldn't disagree at all with that but I'd hazard a guess that at the hint of any such legislation there would be lobbying by interested parties to ensure their industry/workforce/employees etc were exempt from such testing...
