Almost all the automated chemiluminescence analyzers in the market cannot detect total 25-hy-droxyvitamin D (25-OH VD) in fingertip blood sample due to the limited volume. This study aimed to develop a relatively simple pretreatment method to obtain plasma from the fingertip blood samples with limited volume and to establish and evaluate the performance of a chemiluminescence immunoassay (CLIA) for detecting 25-OH VD in plasma. Fixed volume of plasma was obtained using a special glass capillary to pretreat the fingertip blood. The co
