PcimOlki pisze:In most clinical pathology laboratories, creatinine is measured by the alkaline picrate reaction. This reaction is not entirely specific for creatinine and measures another group of substances collectively known as noncreatinine chromagens. These substances are found in plasma, where they may constitute up to 50% of the measured creatinine at normal serum creatinine concentrations, but only small amounts appear in urine. [...]

Normy IRIS bodajże to uwzględniają:
"Serum creatinine concentration should be measured using standard automated methods (i.e., Jaffe colorimetric reaction). The serum creatinine concentrations proposed in the IRIS guidelines do not refer to creatinine determined by enzymatic methods."
