An object of the present invention is to provide an APTT measuring reagent with improved lot-to-lot difference and / or vial-to-vial difference and improved quality. In the final stage of preparation of an APTT measurement reagent, that is, in an inspection process after manufacturing a reagent, an inspection method capable of reflecting a difference in measured values between lots and / or vials is introduced. Specifically, it is based on introducing a test method for measuring APTT of control plasma using an APTT measurement reagent diluted at a certain dilution factor. |
