I was given a blood test last month along with my regular U.A. The U.A. tests are given everytime I go in. I had a blood test done in Oct.2009. I was told this would be a blood test for amount of vitiam D. On the way home from visit I started thinking about this. Doesn't seem right to me. I think he is testing for amount of meds. in my system. Is it alright for a dr. to lie to you regarding why a blood test is being given?
