Abstract
Disclosed is a method of measuring the prostaglandin E main urinary metabolite (PGE-MUM), in which a mixture solution of a urine sample treated with alkali can directly be subjected to an antigen-antibody reaction system in an immunoassay of PGE-MUM, without neutralization and dilution followed by dispensation. The method of measuring PGE-MUM includes the steps of: a) mixing a urine sample with an alkaline aqueous solution, and b) subjecting the mixture solution resulting from a) to an immunoassay using a bicyclo PGE-MUM-immobilized or anti-bicyclo PGE-MUM antibody-immobilized solid phase to measure PGE-MUM in the urine sample, wherein the immunoassay is performed in a weakly-acidic basal buffer solution in the presence of a second pH buffering agent which exerts a buffering effect in the basic range and is different from the pH buffering agent contained in the basal buffer solution, and in the presence of a cationic surfactant.
