REAGENT KIT USED FOR DETECTING LIPOPROTEIN-ASSOCIATED PHOSPHOLIPASE A2, AND PREPARATION METHOD AND APPLICATION FOR REAGENT KIT

A reagent kit used for detecting lipoprotein-associated phospholipase A2, and a preparation method for the reagent kit. The reagent kit comprises one or a plurality of first anti-lipoprotein-associated phospholipase A2 antibodies used for binding lipoprotein-associated phospholipase A2 to be measured, and one or a plurality of second anti-lipoprotein-associated phospholipase A2 antibodies marked with a trace marker and binding with the lipoprotein-associated phospholipase A2 to be measured at another site, different from the binding site of the lipoprotein-associated phospholipase A2 to be measured and the first anti-lipoprotein-associated phospholipase A2 antibodies. The reagent kit also comprises a displacing agent, so as to further increase the detection accuracy of the reagent kit. A method using the reagent kit for the detection of lipoprotein-associated phospholipase A2 may take serum as a detection sample, has high repeatability and high accuracy, and measures the concentration of lipoprotein-associated phospholipase A2 in the sample in a highly sensitive manner.
