Design of microfludic chip for blood typing system

Blood typing is a critical test for transfusion and many medical procedures. The traditional methods using microplate or automated test system are either laborious or requiring expensive equipment. In this study, a microfluidic chip using centrifugal actuation by servo motor is presented. The sample and reagents are driven one by one into the reaction chamber on the chip for blood typing test. By observing the agglutination of red blood cells from the reaction chamber, we demonstrate the feasibility of the chip by blood typing experiment. This proposed microfluidic chip has merits of smaller consumption volume of reagents, shorter reaction time, and inexpensive motor actuation.
