摘要： An apparatus and method for platelet multi-function analysis using measurement of electrical characteristics, and a stirring microchip are provided. The apparatus for platelet multi-function analysis includes a stirring microchip that has a sample storage chamber formed therein to hold a blood sample, and in which an inner part of the sample storage chamber is coated with reagents composed of collagen and epinephrine, or collagen and ADP. The apparatus for platelet multi-function analysis further includes a microstirrer installed inside the stirring microchip to stir the blood sample and the reagents in the stirring microchip and a stirring induction unit configured to facilitate stirring of the microstirrer. Therefore, the platelet aggregation and multi-function analysis can be performed using a trace of blood, and the platelet aggregation and multi-function analysis can also be performed using the whole blood taken from the veins through a vacuum tube containing an anticoagulant.
