Additional information needed The Jaffe reaction is a colorimetric method used in clinical chemistry to determine creatinine levels in blood and urine. In 1886, Max Jaffe (1841–1911) wrote about its basic principles in the paper Über den Niederschlag, welchen Pikrinsäure in normalem Harn erzeugt und über eine neue Reaction des Kreatin… WebFeb 17, 2008 · The disadvantage of the kinetic Jaffe creatinine determination is its low specificity. This was improved by the enzymatic, compensated-Jaffe and high resolution liquid chromatographic assays introduced in the last decade. Creatinine values determined by the new methods are more accurate, but give lower creatinine values, therefore the ...

WebJan 1, 2004 · The results were also compared by plotting the difference for creatinine measurements (HPLC − Jaffe) vs the mean concentration according to the method of Bland and Altman . Analysis by the Jaffe method gave urinary creatinine concentrations that were lower than those measured by HPLC in the whole concentration range (0.2–33 mmol/L). WebApr 3, 2024 · Although simple and inexpensive, Jaffe methodology is nonspecific because alkaline picrate can react with any compound containing a methylene group ( 6, ). Glucose, ketones, and protein can cause falsely elevated creatinine readings, whereas bilirubin can produce falsely low results ( 7, 8, ).
