  A process for measuring the degree of coloring of a color producing reagent to be reduced such as a tetrazolium salt with color developing assistants can be applied to clinical examinations such as determination of the amount of H2O2 and determination of peroxidase activity without much suffering from influences of ascorbic acid, bililubin, etc. present in samples.

  用显色助剂测量待还原的四唑鎓盐等显色试剂的着色程度的方法可用于临床检查，如测定 H2O2 的量和测定过氧化物酶的活性，而不会受到样品中抗坏血酸、胆红素等的影响。
