Method for determining false positive reaction of urinary protein in qualitative analysis using color reaction and qualitative analyzer using same

摘要

PROBLEM TO BE SOLVED: To provide a method for determining false positive reaction of urine protein in qualitative analysis using color reaction and a qualitative analyzing device using the same method.SOLUTION: A method for determining false positive reaction of urine protein in qualitative analysis using color reaction comprises the steps of: bringing urine into contact with a reagent part of an inspection object provided with a reagent for urine protein and color reaction; measuring the color of the reagent part at least twice immediately after bringing the urine into contact with the reagent part and after end of the color reaction; and determining whether the urine protein indicates positive reaction or false positive reaction on the basis of an amount of change of a blue component obtained from color information of the measured reagent part or on the basis of an amount of change of a blue component ratio, a red component ratio, or a green component ratio.
