Quest labs has had erroneous Vitamin D tests all over the country in the past 2 years. Very interesting.

"Yet many experts say that even if the tests were accurate, there would still be uncertainty in how to treat patients. There is considerable debate about how much vitamin D is needed and whether vitamin D supplements even prevent various diseases.

....

Meanwhile, the F.D.A. is considering increasing its role in regulating diagnostic tests. Now, test kits sold to labs, hospitals and doctor’s offices must be approved by the agency. But tests developed and offered by a single laboratory, like the Quest vitamin D test, do not."

I strongly believe that people should not go above what is currently recommended by the FDA, no matter what some "trendy" new study shows.

I strongly believe I should not go above what my neurologist and GP have recommended for daily intake of Vitamin D. I let the experts do the math!

This is interesting....

I didn't have that test done at Quest (where my gp uses) because I had no insurance so she sent me to the local hospital to have it done. Came back very low. She now has me on 50,000iu's a week for the next 6 months.

I would definitely say go by what the docs tell us....but I am going to question the neuro as well on Friday when I see her.

Fair enough, IF he had you tested at a reliable lab. I'm pretty sure they test differently in Canada (my results were given in a different measurement), so as long as you are deficient, and are being monitored regularly for toxicity, etc. . . I suppose it's all good.

Apparently I was not deficient in anything, surprisingly. I just take 1000 IU of D daily.

I've recently started taking 1000 IU of Vitamin D. What potential harm can excessive Vitamin D cause?
