摘要：
A reagent kit for measuring coagulation time is described herein. This reagent comprises calcium chelator which interferes with the reaction between calcium and substance other than a coagulation factor in a blood sample, and which substantially does not interfere with coagulation reaction.A method for measuring coagulation time is also described herein. The method comprises a contacting step and a measuring step. The contacting step is to contact a blood sample, calcium and compound selected from the group consisting of partial thromboplastin, tissue thromboplastin, and complex of tissue factor and phospholipid, in the presence of calcium chelator. This calcium chelator can interfere with the reaction between calcium and substance other than a coagulation factor in the blood sample and substantially does not interfere with coagulation reaction. The measuring step is to measure coagulation time of the blood sample.
