I don't think it's "most" in terms of numbers, but "most up to date and concerned" doctors, a dramatically smaller cohort. It should indeed be the standard practice, but as you can see from this thread alone, neither DavidCPA nor Christine have had it done despite regular doctors' visits. Sad to say, despite weekly blood tests for my two months of chemo for multiple panels, there was not even one Vitamin D test. It was my cardiologist who insisted on it and now I have my endocrinologist monitor it since I have to get regular TSH (thyroid) blood work anyway
My wife and son both have primary care physicians and neither of them have had Vitamin D tests for their physical exams.
I'd be interested to hear if your area is a bright spot of medical care after you hear from your sister.
