Vitamin D Labs

Hi all,
I got my lab results back, and I am entering them in to the spreadsheet I got from Pam's blog.

My question is about the Vit D results.  The spreadsheet has a spot for Vit D, 25 hydroxy.  My lab results show two numbers: One for 25HD, which I am assuming is the 25 hydroxy, and one that says DHVD.  Does anyone know what that second one is and what the "normal" range is for us?

I could Google it, but I would much rather someone that knows what this is explain it to me.

Thanks!!

you can search the definiton on this site and see what the results mean too.

I checked the lab results website, but it doesn't say what a normal range is for us.  I'm kind of worried about the 1, 25-dihydroxy number because that is marked high on my results sheet.

 Mmm..... here's what I know.  25HD and 25 hydroxy are the same thing. HD stands for Hydroxy Vitamin D.  The 25 part means they testes the actual circulating vitamin D in your blood.  So if it's the same ting, not sure why there would be two results. Odd.  

If it says 1,25... that is more like a snapshot of what was happening in that instant that blood was drawn --- this is not what we want, it's virtually worthless information for testing vitamin D (so if that's on your report, just ignore it).  

There's also a test for Vitamin D that shows the difference between D2 and D3 --- but that's usually very well spelled out if they tested both. 

As for DHVD.... no idea what that mean, never heard of it and can't find anything online about what it means. You can call the lab if you need to, they are the ones who know for sure what their own abbreviations mean.  :-)

Guess I wasn't much help, huh?  

 Oh.  Forgot to answer the other question.  Ideal Vitamin D levels (with D2 and D3 combined to equal one total) is 80-100.  Here's the deal:

30-100 --- this is what the lab classifies as normal range

30-50 ng/ml -- with Vitamin D number in this range your body is simply using up all your Vitamin D as fast as you're putting it in.  Scientists consider this level to be too low...

50 ng/ml -- once your levels are consistently at 50 then you're finally able to store enough D for a rainy day

80-100 ng/ml -- studies are showing that levels over 80 have a direct result on lower cancer rates (breast cancer risk decreases by 50%, etc.) and lower risk for multiple sclerosis, osteoporosis and a bunch of other things.
