Hi gandc:
My first test was about 10 ng/ml in a range of 1 to 100.
As there are many different ranges from lab to lab, and country to country,
the best way to avoid confusion is to elevate your D3 somewhere between
50% to 70% of any range. This level is good for neurosis. Of course, all this should be done
under the supervision of an up to date doctor.
Best wishes,
Ali
