WebThe normal serum creatinine (sCr) varies with the subject's body muscle mass and with the technique used to measure it. For the adult male, the normal range is 0.6 to 1.2 mg/dl, or 53 to 106 μmol/L by the kinetic or enzymatic method, and 0.8 to 1.5 mg/dl, or 70 to 133 μmol/L by the older manual Jaffé reaction. WebDec 22, 2016 · Both are colorimetric methods. In Jaffe methods, serum creatinine reacts with picrate to give a yellow-orange colour that can be quantified. This reaction is, however, not fully specific, as picrate can also react with other components, known as pseudo-chromogens (acetoacetate, pyruvate, keto-acids, proteins, glucose, and ascorbic acid) …
Webreaction and the Jaffe reaction. In the Berthelot reaction, urea is converted to ammonium using urease, ammonium ion which then reacts with a mixture of salicylate, sodium nitroprusside, and hypochlorite to produce blue-green chromophore. In the Jaffe reaction, sCRE in alkaline conditions reacts with picric ions to form an orange complex. Web11.9 Laboratory Measurements of Creatinine and Related Tests.
