The present invention relates to a method for analysing blood samples from dried blood spots on filter paper. In particular, the method of the invention may comprise the steps of: a) providing a degradable cellulosic filter paper, b) placing a blood sample on said degradable cellulosic filter paper, c) drying said blood sample on said degradable cellulosic filter paper, thus providing a dried blood spot, d) punching out a small disc of said dried blood spot and moving it to a reaction vessel, e) degrading said degradable cellulosic filter paper from said dried blood spot with a cellulase in presence of an aqueous acidic solution, thus providing a blood sample, and f) analyzing said blood sample; wherein said cellulase is selected from the group comprising endoglucanase, exoglucanase, hemicellulase and/or beta-glucosidase. |
