Activated partial thromboplastin time measuring reagent and reagent kit and method for suppressing precipitation of ellagic acid compound

摘要

Problem to be solved: to provide an active partial thromboplastin time (APTT) reagent and a reagent kit in which the environmental load is low and the chemical substance which can suppress the precipitation of the ellagic acid compound is suppressed, and the precipitation of the ellagic acid compound is suppressed.Solution: an agogic acid compound and a compound represented by the formula (I) below (formula x) is a hydrogen atom, - (C = O) - y, or - (C = O) - Oz, y is a straight or branched chain alkyl group or a phenyl group having a hydroxyl group, a hydrogen atom, a number of carbon atoms greater than or equal to 1 or more, and Z is an alkali metal The above described problems are solved by the reagent for reagent measurement for APTT measurement and the reagent kit containing the reagent.No selection
