It's important to know exactly what your results were, including the units. Was it ng/ml or nmol/l? And was that the level of 25-hydroxycholecalciferol (25-D or calcidiol), or 1,25-dihodroxycholecalciferol (1,25-D or calcitriol)?
>and what is this D 2?
Vitamin D2 is ergocalciferol. Prescription strength vitamin D is usually in this form, more as a tradition than for any other reason. Most OTC supplements are Vitamin D3, cholecalciferol. In food, plants supply D2, whereas animal sources are D3.

I don't know if you're getting unreliable information or not, but if you let me know your actual lab results, I can hazard a guess.
In the last decade, minimum recommended intake levels for vitamin D have been raised three times. Some labs, and some doctors, may not have kept pace with the news.
