Abstract
A method for quantitating vitamin D metabolites directly in blood plasma or serum, without the need for prior purification of the vitamin D metabolites, comprising a digestion of the serum proteins with a serine protease such as proteinase K and sequence of steps for inhibiting the proteinase K activity in the competitive binding analysis. The advantages of this method are its high accuracy over the whole range of physiologically relevant values and that it can be easily adapted for a fully automated analysis of serum and plasma samples.
