Ok here goes my Feb 2010 results. Been taking D3 4000 iu's for past 6 months. 2000 prior 3 yrs. I'll recheck during summer sun season.

25-OH total 44 ng/ml
25-OH, D3 44ng/ml
25-OH, D2 <4 ng/ml
1,25 (OH)2, total 56 pg/ml
D3, 1,25 (OH)2 56 --/ml
D2, 1,25 (OH)2 <8 --/ml

from results paper:
25-OHD3 indicates BOTH endogenous and supplimentation.
25-OHD2 is an indicator of exogenous sources such as diet or supplimentation.
Values for subcomponents D2 (derived from plant or fungal sources) and D3 (derived from human or animal sources) are provided for imformational purposes only.

Asked the hema/oncologist to check 2&3. He wasnt familiar with anything other then checking total. I said wow to self I thought cancer and D would be important. So, he had nurse pick a couple tests from book. I knew about the 2&3 because my nephew is allergic to everything and my sister told me his D total was 20 and his sister that could kick his butt (9 he's 12 maybe?) has a level of 50.
