The jaffe method
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, ). WebNov 19, 2024 · The development of the rate-blanking method to counteract this interference might explain the false-positive interference. However, enzymatic assays are more specific than Jaffe . But bilirubin can also interfere negatively with enzymatic methods, particularly the methods based on creatinine amidohydrolase (creatininase) (1, 4).
