title: [A rapid method for assay of 25-hydroxyvitamin D in serum].
abstract: A simplified assay for 25-hydroxyvitamin D is reported. In this procedure ethanol extraction is used in order to obtain a better protein precipitation and a higher recovery of added tritiated 25-hydroxyvitamin D3. Extraction is followed by column chromatography on Sep-pak Silica cartridges. The eluate is dried and directly used for competitive protein binding assay. The method shows two main advantages: it is less time consuming and is easier to perform than existing procedures.
