Provided is a kit used to distinguish sdLDL-C from a sample, the kit comprising: a first reagent composition having at least one activity selected from the group consisting of cholesterol esterase activity, cholesterol oxidase activity, and sphingomyelinase activity; and a second reagent composition for quantifying sdLDL-C, wherein in an absorption spectrum after storing the first reagent composition at 37 °C for 2 weeks, the ratio R1 represented by ABS400/ABS450 is 0.90-3.00, and in an absorption spectrum after storing the second reagent composition at 37 °C for 2 weeks, the ratio R1 represented by ABS400/ABS450 is 0.90-8.00. |
