The present invention provides a method for measuring the concentration of an analyte in a test solution wherein the analyte is mevalonic acid and/or 3-hydroxymethylglutaryl coenzyme A, comprising the following steps (p) and (q): (p) a step of allowing an enzyme that catalyzes a reaction represented by Reaction Formula 1 and an enzyme that catalyzes a reaction represented by Reaction Formula 2 to act on a test solution containing mevalonic acid and/or 3-hydroxymethylglutaryl coenzyme A in the presence of a hydrogen acceptor X, a hydrogen donor Y, and coenzyme A; and (q) a step of measuring an amount of: a reduced hydrogen acceptor X that is produced; or an oxidized hydrogen donor Y that is produced; or a hydrogen acceptor X that is decreased; or a hydrogen donor Y that is decreased, wherein the hydrogen donor Y and the reduced hydrogen acceptor X are not the same.
本发明提供了一种测量试液中分析物浓度的方法,其中分析物为甲羟戊酸和/或3-羟甲基戊二酰辅酶A,该方法包括以下步骤(p)和(q):(p) 让催化反应式 1 所代表的反应的酶和催化反应式 2 所代表的反应的酶在氢受体 X、氢供体 Y 和辅酶 A 的存在下作用于含有甲羟戊酸和/或 3-羟甲基戊二酰辅酶 A 的试液的步骤;和 (q) 测量以下物质的量的步骤:产生的还原氢受体 X;或产生的氧化氢供体 Y;或减少的氢受体 X;或减少的氢供体 Y,其中氢供体 Y 和还原氢受体 X 并不相同。
