Ok, here is the test name:
Vitamin D, 25 - Hydroxy, LC/MS/MSReference Range 20 - 100 ng/mL
Vitamin D, 25 - OH, Total, Out of Range 15
Vitamin D, 25 - OH, D3 this one is listed under the "in range" 15, although it is not in the range.
Vitamin D, 25 - OH, D2 also under the "in range" <4
Then it says: Vitamin D, 25 - OH, D3: Endogenous form of Vitamin D present in the body.Vitamin D, 25 - OH, D2: Used for therapeutic purposes in Vitamin D deficient states.
This test was performed using the LC/MS/MS methodolgy.
25-OHD3 indicates both endogenous production and supplementation.
25-OHD2 is an indicator of exogenous sources such as diet or supplementation.
Therapy is based on measurement of Total 25-OHD, with levels <20 ng/mL suggesting Vitamin D deficiency while levels between 20 and 30 suggesting insufficiency. In both situatios there is need for intense to moderate supplementation. In patients using D2 (ergocalciferol) supplementation, levels of 4 ng/mL of 25-OHD2 or greater suggest compliance.
That's the whole page on Vitamin D
And my prescription is for D3 @ 50,000
All the pharmacies I have called have D2 and tell me it's the same thing , Vit D is Vit D.
I know better than that. And it's $20. I want to be sure I get the Correct D since it's such a high dose.Please share with me your thoughts, when you can.
Oh, and Maddie, I don't drink milk. I rarely go outside either. My doctor thought I had hypothyroid, and I read that hypothyroid interferes with metabolization of Vit D. My ranges came back within normal range though (2.15 , Their range was .4 - 5.5). So I guess mine is caused by years of avoiding the sun...
