Hi! Just got my 25-OH D result made in private clinic in Croatia. Results are 38.8 nmol/L (15.2 ng/ml) The strange thing with my results is that I am in between range references because they are 12.3 – 107. I checked whole internet and everywhere is listed: nmol/L 50 – 200 ng/ml 30 – 100 and here, 12.3 – 107 (Analise with Cobas e411 Roche) I know that laboratories are using different methods but isn't this a little bit strange? How can my results be good with 15,2 ng/ml???

    I forgot to mention that my test result and range references (12.3 – 107) are written in nmol/L

    Let’s start with you are correct that 38.8nmol/l equals 15ng/ml. Here in the US the Vitamin D reference range is usually 30 to 100ng/ml. (This translates to 75 to 250nmol/l.) If I understand you correctly the range they are using to be healthy is 12.3 to 107nmol/l. Again this translates to about 5 to 43ng/ml. So the reference range they are using is “very bad”. No one here in the US would disagree that anything below 20ng/ml is NOT healthy. The question becomes is 20-30ng/ml a good level or do humans need higher levels.
    The answer here at the Vitamin D Council and other organizations is that levels definitely below 40ng/ml are not good and we recommend a minimum of 50ng/ml (125nmol/l). This is based on studies and research.
    So to be healthy it takes most average weight people (150lbs), taking 5000iu of Vitamin D a day, to reach a blood level of 50ng/ml. If you weigh more or already in a diseased state, then you may need to take more.
    I would also recommend reading http://www.vitamindcouncil.org/about-vitamin-d/vitamin-d-and-other-vitamins-and-minerals/.
