For the measurement of creatinine levels in urine.

• Measure creatinine levels in urine
• Assay 40 samples in duplicate
• Measure creatinine levels down to 0,1 mg/dl
• Plate-based colorimetric measurement (490 to 500 nm)

Creatine is synthesised in kidney, liver, and pancreas and transported to muscle and brain where it is phosphorylated to phosphocreatine. Some free creatine in muscle is converted to creatinine. The amount of creatinine produced is proportional to an individual’s muscle mass. In the absence of renal disease, the excretion rate of creatinine in an individual is relatively constant. Thus, urinary creatinine levels are commonly used as an index of standardisation for a variety of other tests. Measurement of creatinine clearance is also useful in detecting renal disease and estimating the extent of impairment of renal function.
