creatinine

 [kre-at´ĭ-nin]
a nitrogenous compound formed as the end product of creatine metabolism. It is formed in the muscle in relatively small amounts, passes into the blood and is excreted in the urine. A laboratory test for the creatinine level in the blood may be used as a measurement of kidney function (see creatinine clearance).
creatinine clearance test a test of renal function based on the rate of creatinine clearance.

creatinine clearance test

a diagnostic test for kidney function. It measures the rate at which creatinine is cleared from the blood by the kidney.

creatinine clearance test

A test of the rate at which the kidneys are removing CREATININE from the blood. This is an index of the rate of filtration of the blood by the kidneys and thus of their health and efficiency.

creatinine

a nitrogenous compound formed as the irreversible end product of creatine metabolism. It is formed in the muscle in relatively small amounts, passes into the blood and is excreted in the urine.
A laboratory test for the creatinine level in the blood may be used as a measurement of kidney function. Since creatinine is normally produced in fairly constant amounts as a result of the breakdown of phosphocreatine and is excreted in the urine, an elevation in the creatinine level in the blood indicates a disturbance in kidney function.

creatinine:blood urea nitrogen ratio
determination of blood creatinine and blood urea nitrogen (BUN) and the relationship between them is an additional assessment of renal function. It may be useful in the differential diagnosis of azotemia and in monitoring renal disease when protein-restricted diets are being given.
creatinine clearance test
a measure of renal function based on the rate at which ingested creatinine is filtered through the renal glomeruli.
creatinine:cortisol ratio
see cortisol:creatinine ratio.
creatinine-protein ratio
protein-creatinine ratio.
urine creatinine/serum creatinine ratio
used to distinguish between prerenal and renal azotemia.
