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.

cre·at·i·nine (Cr),

(krē-at'i-nēn, -nin), Do not confuse this word with creatine.
A component of urine and the final product of creatine catabolism; formed by the nonenzymatic dephosphorylative cyclization of phosphocreatine to form the internal anhydride of creatine.

creatinine

(krē-ăt′n-ēn′, -ĭn)
n.
A creatine anhydride, C4H7N3O, formed by the metabolism of creatine, that is found in muscle tissue and blood and normally excreted in the urine as a metabolic waste.

creatinine

Nephrology The end product of creatine metabolism, which is excreted into the urine; creatinine can be used to diagnose and monitor renal failure; creatinine may be measured in amniotic fluid to determine gestational age–fetal maturity index; normal ranges vary according to the lab. See Creatinine clearance.

creatinine

A breakdown product of the important nitrogenous metabolic substance CREATINE. Creatinine is a normal metabolic waste substance and is found in muscle and blood and excreted in the urine.

creatinine

the nitrogenous waste material of muscle creatine.

Creatinine

The metabolized by-product of creatine, an organic acid that assists the body in producing muscle contractions. Creatinine is found in the bloodstream and in muscle tissue. It is removed from the blood by the kidneys and excreted in the urine.

Besides the elderly, very fit men may run a high creatinine. As creatinine is a breakdown product for muscle tissue, increased muscle mass will cause a higher baseline creatinine.
Five millilitres of blood was collected from antecubital vein of each subject under aseptic conditions and serum was subsequently obtained through ultracentrifugation which was subsequently stored at-80 degrees Celsius in Eppendorf tubes for the measurement of biochemical parameters i.e.; Cystatin-C and creatinine.
The meta-analysis study searched a number of sites, including, China National Knowledge Infrastructure databases, PubMed, Google Scholar, and Cochrane Library to identify randomized controlled trials that determine the diagnostic value of Cystatin C and creatinine, for estimating GFR in patients with CKD.
On the basis of creatinine excretion, her SM mass was 26 kg (9.2 kg [m.sup.-2]) on the first admission and 10.2 kg (3.6 kg [m.sup.-2]) on the second admission.
1 and 2 show 24-h variability profiles of creatinine, cystatin C, and all eGFR equations for both study groups.
This is because eGFR includes other factors apart from creatinine that influence kidney function namely age, sex.
Due to these characteristics, cystatin C has been suggested as a good marker for the glomerular filtration rate (GFR).7 Some of the published research proposed that cystatin C was better than creatinine in relation to an AKI diagnosis.
Values of creatinine were transformed to eGFR using the MDRD and Lund-Malmo (L-M) and CKD-EPI formulae.
The stock standards were prepared at a concentration of 500 [micro]g/mL for each analyte, uric acid, creatinine, and hypoxanthine in 100 mL volumetric flasks with deionized water or urine.
Population was further divided into three sub groups depending on the albumin creatinine ratio (ACR).
He and his associates conducted a meta-analysis comparing cystatin C and creatinine in determining prognosis for patients with baseline kidney disease.
