Clinical Significance
The total 25-OH Vitamin D level includes the D2 and D3 forms as part of the total result. It is the predominant circulating form of Vitamin D and is considered to be the most reliable index of a person's Vitamin D nutritional status. It reflects Vitamin D produced cutaneously and that obtained from food and supplements.
