The Ni2+/S2O4(2-)-test makes semiquantitative assessment of cystine concentration in urine possible. The reaction principle of the method is based on the formation of a nickel/cysteine/sulfide complex of brown colour. Visual test evaluation is done by classifying the colour intensity of the sample/reagent mixture according to an exact colour shade. Each colour shade on a colour reference table is correlated to a certain range of cystine concentration. Cystine determination is described in detail for two ranges (0.60 and 1.25 mmol/l).
Ni2+/S2O4(2-)检测法可对尿液中的胱氨酸浓度进行半定量评估。该方法的反应原理基于棕色镍/半胱氨酸/硫化物络合物的形成。通过根据精确的色泽对样品/试剂混合物的颜色强度进行分类来进行目视检测评估。颜色参考表上的每个色泽都与特定范围的胱氨酸浓度相关。详细描述了两个浓度范围（0.60和1.25 mmol/l）的胱氨酸测定方法。
