Evaluation of an Enzymatic Method for Determining Serum Creatinine Assay
The enzymatic method for the determination of serum creatinine is accepted as one of the standard method in a clinical laboratory. The enzymatic method for the determination of serum creatinine was optimized for use with Merilyzer AutoQuant-400 auto analyzer and its performance characteristics were practically compared with Jaffe’s Kinetic. Effects of some interfering substances like Serum bili...
متن کاملKinetic enzymatic method for determining serum creatinine.
Creatinine amidohydrolase is used to measure serum creatinine in a totally enzymatic procedure. Creatine, produced by hydrolysis, is acted upon by creatine kinase, and then by pyruvate kinase and lactate dehydrogenase, to result in a change in absorbance at 340 nm. The amount of creatinine present is related to the rate of change in A340 and is determined from a standard curve. Absorbance and c...
متن کاملEvaluation of an enzymatic method for determining creatinine in plasma.
An enzymatic kit method for the determination of plasma creatinine was optimised for use with a centrifugal analyser and its performance characteristics and practicability compared with an end point and a kinetic Jaffé-based method. The enzymatic method exhibited several advantages over Jaffé-based methods--namely, smaller sample size, rapid sample throughput (200 per hour), and improved specif...
متن کاملLC-MS/MS Method for Serum Creatinine: Comparison with Enzymatic Method and Jaffe Method
Accurate quantification of creatinine (Cre) is important to estimate glomerular filtration rate (GFR). Differences among various methods of Cre quantification were previously noted. This study aims to develop a liquid chromatography tandem mass spectrometry (LC-MS/MS) method for serum Cre and compare this method with clinical routine methods. LC-MS/MS analysis was performed on API 4000 triple q...
متن کاملAn automated dry-slide enzymatic method evaluated for measurement of creatinine in serum.
We evaluated an automated dry-slide enzymatic method involving creatinine iminohydrolase for measurement of creatinine in serum with the Kodak Ektachem analyzer. The means (and SD) for three commercially available quality-control sera, analyzed during eight weeks, were 9.7 (1.0), 16.6 (0.9), and 61 (2.1) mg/L. The regression equation for 105 samples measured with the Technicon SMAC (x) and Ekta...
