Thank you very much for your very clear professional explanation

I switched to this family doctor in Palo Alto Medical Foundation this year.I found their testing items were not as comprehensive as my previous years' reports. This year, I requested to test Vitamin D and Vitamin B12, and my family doctor told me they could only test Vitamin D. He also did not order my urine test. America is lacking family doctors. I called many other family doctors, and they did not accept new patients.

I will ask him to order test for Vit D 25-OH next year.

Thank you very much for your professional help.
