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).
A simple blood test called the 25-hydroxy vitamin D test can measure levels of vitamin D in the blood. Levels of the vitamin are measured in nanograms per milliliter (ng/mL). 20 ng/mL to 50 ng/mL is an adequate level for bone and overall health, and a level less than 12 ng/mL indicates vitamin D deficiency.
