A few comments since you have had no other
responses:
- It is not at all unreasonable to determine
Vitamin D in someone with unexplained myalgia
- No doubt someone somewhere has put into into a
guideline
- There are some substantial problems and dangers
with the way we have been bullied into reporting
25(OH)D results, and this scenario is one of the
common seen ones.
a) Patient presents with myalgia.
b) GP determines 25(OH)D.
c) Result is 35umol/L
We report as "Consistent with Vitamin D
deficiency/insufficiency (depending on the
penetration of the propaganda) with no other
reasonable indication as to the "unusualness" of
the result.
GP concludes that the myalgia is due to Vitamin D
deficiency.
But in fact the Positive Predictive Value of
result for D deficiency as the cause of myalgia is
far far lower after this test result than it was before.
I have seen several cases where consultant
neurologists have drawn inappropriate conclusions
and have been misled by reporting.
