In the jaffe reaction creatine reacts with
WebThe assay is based on the reaction of creatinine with sodium picrate as described by Jaffé. Creatinine reacts with alkaline picrate forming a red complex. The time interval chosen for measurements avoids interferences from other serum constituents. The intensity of the color formed is proportional to the creatinine WebTheir mean serum lipase activity was 105.07 IU/L ± 127.54 IU/L and 106.98 IU/L ± 88.35 IU/L, respectively. Serum lipase activity was elevated above the normal range and three times above the upper limit of the normal range with a magnitude of 11.2% and 4.2%, respectively. Similarly, 9.1% and 0.7% of diabetic patients had increased serum ...

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) …
