However, PTH can change due to renal function, exercise level, the time of day, or even diet. There has been no consensus on the optimal level of vitamin D intake to reduce PTH, and this is why many laboratories report the normal range of vitamin D to be so wide (20 to 40 ng/ml, or in some cases, 50 to 100 nmol).
In fact, your vitamin D is low because in reality, a level of 40 nmol/L is equal to 16 ng/ml.!! He totally forgot to look closely at the units. Also, note that the upper limit of normal as reported by many laboratories is also inaccurate. The upper limit of normal should be 100 ng/ml (250 nmol/L).
