Enzymatic Creatinine Assays Erode The Jaffe Method
The picrate-based Jaffe reaction has measured creatinine in clinical chemistry for over a century, and enzymatic methods now displace it in higher-throughput laboratories because they suffer less interference from bilirubin, glucose and drug metabolites. Roughly 22% of clinical chemistry creatinine testing has now moved across to enzymatic methods, against about 12% only five years earlier. The substitution is slow because Jaffe reagents cost considerably less and laboratories must revalidate reference ranges to switch. It is nonetheless entirely one-directional, and it affects the largest single demand pool in this whole market.
