LC-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 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 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 کاملA Risk Assessment of the Jaffe vs Enzymatic Method for Creatinine Measurement in an Outpatient Population
BACKGROUND The Jaffe and enzymatic methods are the two most common methods for measuring serum creatinine. The Jaffe method is less expensive than the enzymatic method but is also more susceptible to interferences. Interferences can lead to misdiagnosis but interferences may vary by patient population. The overall risk associated with the Jaffe method depends on the probability of misclassifica...
متن کاملSpecificity characteristics of 7 commercial creatinine measurement procedures by enzymatic and Jaffe method principles.
BACKGROUND Standardized calibration does not change a creatinine measurement procedure's susceptibility to potentially interfering substances. METHODS We obtained individual residual serum or plasma samples (n = 365) from patients with 19 different disease categories associated with potentially interfering substances and from healthy controls. Additional sera at 0.9 mg/dL (80 μmol/L) and 3.8 ...
