Abstract: Disclosed is a reagent for determination of activated partial thromboplastin time, comprising: a phosphatidylcholine (PC); a phosphatidylserine (PS); and a phosphatidylethanolamine (PE), wherein a concentration ratio of the PS relative to the PC is not less than 0.16 and not more than 0.25, and a concentration of the PS is not less than 7 ?g/mL and not more than 13 ?g/mL.

Abstract: Disclosed is a method for measuring activated partial thromboplastin time, the method comprising: mixing: a blood sample; a first reagent comprising an ellagic acid compound and a compound represented by Formula (I); and a second regent comprising a calcium ion; and measuring activated partial thromboplastin time using the mixture prepared in the mixing step, wherein the compound represented by Formula (I) is shown below wherein X is a hydrogen atom, —(C?O)—Y, or —(C?O)—OZ, Y is a hydroxyl group, a hydrogen atom, a linear or branched alkyl group having a carbon number of 1 or more and 6 or less, or a phenyl group, and Z is an alkali metal.

Abstract: Sample pretreatment solutions for influenza virus tests by immunochromatography are described. Methods detecting influenza virus by immunochromatography using the sample pretreatment solutions and Kits comprising the sample pretreatment solution and an immunochromatographic device are also described.

Abstract: An immunochromatographic test device of the present invention comprises: a sample receiving member for receiving a sample; a label holding member for holding a labeling substance to bind to an analyte contained in the sample; and a chromatographic membrane having a detection zone at which an immobilization substance to bind to the analyte is immobilized, wherein the sample receiving member disposed to cover the label holding member and in contact with the chromatographic membrane, and the chromatographic membrane is spaced apart from the label holding member.

Abstract: A test kit for immunochromatography comprising a test strip and a test tube is described. The test strip comprises a detection zone for detecting an analyte in a sample. The test tube accommodates the test strip. The test tube comprises an indicator at a position corresponding to the detection zone of the test strip which is inserted into the test tube.

Abstract: A pretreatment method for enhancing relativity and reaction specificity prior to the detection or determination of an ingredient, especially a microorganism ingredient, contained in a biosample; and a pretreating fluid therefor or a reagent for determination containing the pretreating fluid. The pretreating fluid(or reactive fluid), which is for the determination of an ingredient contained in a sample to be tested, comprises at least an organic acid or a salt thereof. If preferably comprises: at least one member selected among surfactants and substances capable of reduction; and an organic acid or salt thereof. Treatments with the pretreating fluid were found to eliminate problems and the invention has thus been completed.
