The Cypress Diagnostics kit Creatinine is an in vitro diagnostic medical device intended to be used for the quantitative measurement of creatinine in human serum or heparinized plasma. The device is not automated. The measurement of creatinine is intended to be used for the screening for and aid in diagnosis of kidney disease and the monitoring of the effectiveness of kidney disease treatment.

Most of the creatine is found in muscle tissue where it is present as creatine phosphate and serves as a high energy storage reservoir for conversion to ATP. Creatinine, the waste product of this reaction, is transported to the kidneys and eliminated. Independent of the diet, serum creatinine concentration depends almost entirely upon its excretion rate by the kidneys. For this reason, its elevation is highly specific for kidney diseases.
