Hi newTOSFN Thanks for the reply, I am not sure how the numbers work I got them off my past test result page from Kaiser. I forgot to put in the 25-hydroxyvitamin D where I had 27 in 3/2018 and 39 in 3/2019 was the 30-100 ng/ml that may be the range? but that's how it was wrote out on the page, are they supposed to add up somehow? Please let me know what you think. On the doctor putting me on D3 supplement I am not sure why she had me put on it she just said my test showed I was low, but it might have been a good thing I think as 3 months later I had to go in as I had a bone spur in my neck and chronic arthritis in my neck area.
