What about the conflicts of interest of some laboratory professionals who are promoting this tes? for example on lab-tests-online-USA where one can read thar vitamine D needs to be measured "periodically to monitor treatment of vitamin D deficiency"

Yes, enormous waste of money.
Craig Webster has some interesting data on how we might be investigating the wrong people, even with all those investigations being done. An excellent example of the Inverse Care Law.
What went wrong?
* Not enough evidence on what makes a difference
* Not enough agreement on how to use that evidence: should that have been local. regional, national, international protocols?
* Our usual desire for convenient analyses, rather than those that give the best clinical bangs per buck

In France vitamine D measurement in blood is now the 5th lab test in terms of costs for the "sécurité sociale": it costed almost 100.000.000 Euros in 2111, and the number of requests of vitamin D are increasing exponentially: the costs were below
40.000 Euros in 2009. At such a speed of increase, it would not be surprising that the costs would reach 150.000.000 Euros in 2013 and thus vitamin D would become the 2nd most costly test for the collectivity in France just after blood cell counts which cost
300.000.000 Euros each year (quite stable).
I would be interested to know whether or not such a waste of collective ressources are specific to France or if the same happens elsewhere in the world, particularly in the UK.
