Kidney disease

Vitamin D Binding Protein (VDBP) significantly decreases in case of kidney disease. This decrease leads to an increase in the free 25OH Vitamin D concentration, at constant total 25OH Vitamin D levels. Therefore several research groups have studied the importance of free 25OH Vitamin D during kidney disease.
