Hi, As I recall the blood calcium was normal. No I was not taking D at the time. The Dr didn't seem to be able to explain it really. Could only say they are different but of course she did not believe in Hair analysis. But it was correct. Turned out I had level 3 Calcium shell and my xrays eventually showed up little bone spurs from too much calcium occurring on spine and one knee. Been a bit hassle and lot of pain
