My result gives them separately and a total figure. Best to check. 146 os Ok while 75 isn't.
You need to know the units. US web sites say 70 is good as they use different units. In the UK, although 70 nmol/L is over "adequate" , it's not good - only around 30 in the US units, where optimal is 50-70 and deficient is less than 50.
To convert a test result measured in nmol/l to one measured in ng/ml, divide the nmol/l number by 2.5. For example, 50 nmol/l is the same as 20 ng/ml (50÷2.5).
Vitamin D3 is the storage level whereas Vitamin D2 is the circulating level which can vary through the day. They should not be added together - they tell different things.
The site below is packed with information about optimum levels.
Hi Rod, yes, you're correct the way you have explained what I was trying to say. I know that the test to be done is the 25(OH)D as this is the storage form. The 1,25(OH)D is the "active" form and cannot be used as a measure of vitamin D status as it can vary throughout the day. I will look at thee site you have posted - thanks!
Rang endo's secretary to clarify results, she said it was'nt her I spoke to last time I rang and whoever I spoke to gave me the wrong info.
Apparently my G.P. and endo both tested for Vit D one sample went to one lab the other to another lab and the two results went back to the endo. One result was 71.5 the other 75.1
the secretary said whoever gave me the result last time was wrong in what she said.
So for the last few weeks I have been totally confused by someone giving me the wrong information.
Just goes to show how wrong info. is given out and also how labs. can differ.
Bloods were taken on the same day, giving two different results, but still don't know if I am 71.5 or 75.1 whatever I still need to get it a bit higher.
Thanks to all who replied and sorry if I have caused any confusion.
