A quantitative analysis of 3-oxo-5β-steroid which comprises acting 3-oxo-5β-steroidΔ⁴-dehydrogenase on a sample in the presence of a reducing chromophoric agent, and measuring the optical density of the chromophoric substance thereby produced. A typical reducing chromophoric agent is a tetrazolium compound. The invention also provides a reagent for the quantitative analysis of 3-oxo-5β-steroid comprising 3-oxo-5β-steroidΔ⁴-dehydrogenase and a tetrazolium compound. The analysis and reagent provide a simple and reliable method for a liver function test.
