Method and test kit for quantitative determination of Vitamin D metabolites in blood, wherein a predetermined amount of blood is pre-analytically immobilised on a solid sorption material. Thereby, hemolysis of the blood has no effect on the analysis of vitamin D metabolites. For quantitative analysis the dried blood spot on the sorption material is dissolved with an aqueous solvent buffer containing detergent, pH 7.0 to 10.0, and the vitamin D metabolites are eluted with a protic organic solution having a permittivity of less than 35. The eluate is analysed for vitamin D metabolites using conventional methods. |
