Vitamin D

[Queencara78]

Hi all, hope everyone is as well as can possibly be. Can anyone tell me what the difference is between ng/ml and nmol/L for vitamin D blood levels please?

My GP surgery always tells me my results using nmol/L and Im a little confused as to why I keep reading that the nmol needs to be converted to ng/ml by dividing the nmol by 2.496. My recent results were 25 nmol/L in June this year so I was put on 25,000 iu per week for 6 weeks and in increased to 66 nmol/L but no maintenance vitamin management treatment and I requested they test me again two weeks ago and it is down to 34.8 nmol/L. My GP seems to be very relaxed and hasent written another prescription and would rather me wait for what will have been 2 weeks before I see her to discuss it in person.

Nope!!! you need a degree in physics chemistry and medicine to understand how these equations work, as long as a doctor tells you they are normal I dont worry.

not really. failed 1st year chemistry should do Can't remember if it was in higher chemistry or not though.

you need to know the molecular wight of the element i.e. 1 mole and then you can do the conversion. Its just like kms and miles and knowing the conversion process.

This calculator does it for you though : endmemo.com/medical/unitcon...
