True - you should just schedule a blood test. In most US states you can do it yourself without a physician via online lab ordering companies. You will pay out of pocket (or you can use health savings). I usually do this b/c its easier for stuff like this if I am curious about blood levels and procrastinate too much on setting up doctor appts ;) EDIT: Wanted to mention that a Vit D test is usually around 30-50 bucks, so not too expensive
