Beschreibung
Zusammenfassung:	A microfluidic blood serum generator having a first port and a second port, between which there is formed a microfluidic structure, wherein the microfluidic structure has a supply duct communicating with the first port, a clotting region into which the supply duct discharges, and a discharge duct which communicates with the second port and into which the clotting region transitions, wherein the first port is designed to introduce a blood sample at a first pressure and the second port is designed to apply a second pressure that is lower than the first pressure, wherein the clotting region is formed by a single, coherent cavity, and wherein a barrier for retaining a clotted blood sample is arranged in the transition from the clotting region to the discharge duct. A method for separating off blood serum from a blood sample using a blood serum generator of this kind.
