Re: NHS Vitamin D blood test

[Guest guest]

Hi, sorry only just seen this post Beki - but just thought I had to let you know

what the GP at my surgery said when I asked for a Vit D Test - Yes, she agreed

but, wait for it - because I had been supplementing I supposedly have to wait 8

(yes eight) weeks before I do the test !!! I think not. She was obviously new

out of medical school and was eager to please so I ceased the opportunity to

worm a test out of her as my normal GP refuses. I went down the lines that my

chloestrol was slightly raised and although they don't see it as a problem I

know that sun light turns chloestrol into Vit D and maybe my D levels are low -

she agreed to do on this basis and also said she'd check parathyroid too and

calcuim as the three are connected.

I have a good mind to just get it down. I have supplemented 2000 IU per day for

a month, so not mega doses and like others say, if it's high I stop, if it's low

I continue and know that I would need it.

What do others think - how much would a month's supplementation affect my levels

and am I right in thinking i need to be between 50 - 80 to be ok ?

Interested to see what your result will be Beki and I'll post mine next week

hopefully.

I have left enough time without taking it before the blood test?? I have not

taken it today - my test is tomorrow. Will this be enough time to test my own

Vitamin D levels or should I wait till next time and if so how long to leave

without supplement before test?

test other than '1,25-dihydroxy-vitamin D' just to confirm this correct?

This is what I read about Vitamin D: From the American Journal of Clinical Nutrition....
