I have osteoporosis that has become worse over the past 3 years. One problem I found was that my vitamin D, although "normal", was not "optimal" when tested a year ago. This past march I had my vitamin D tested again and it was much higher. It went from 24 to 42.

Then, I looked carefully at the labs I realized the last test that was done was the wrong test! Instead of 25hydroxy-vitamin D the lab did the l.25 dihydroxy-vitamin D.

I called my doctor and he reordered the correct test.

If you want to read more about vitamin D, it can be found in The Gluten File http://jccglutenfree.googlepages.com/vitamind

It is so important to get a copy of all your labs to be sure the results are optimal, the tests wanted were done AND the correct test was done.
