I asked for the test at the suggestion of someone I know at the research center I was at last week (as reported earlier in http://neurotalk.psychcentral.com/thread95701.html). I had seen some news articles about a correlation between PD and Vitamin D deficiency, and, searching this forum, discovered that people have been posting about it for at least a couple of years.

So, when I went to see my internist this week, I asked to have it checked. She thought we had checked it before, but it's not in my electronic record anywhere.

Today's mail brought a lab slip, a prescription, and a letter from my doctor saying that I'm deficient in Vitamin D, with instructions how to take the prescription and, after that, supplements. Low range is 32 ng/mL, high range 100 ng/mL for this particular test result. Mine is at 27.

I'm hoping this will clear up at least a little of my tiredness, as well as saving my bones from turning to cobwebs.

Fellow forumicans, please consider having yours checked, too.
