Serum creatinine is the result of generation, distribution and excretion of creatinine; a lower generation will therefore result in a lower serum concentration for the same GFR, if distribution and excretion remain the same. Serum creatinine is produced by non-enzymatic hydrolysis of creatine, the major sources of this creatine being the release from endogenous muscles and exogenous

as 24 hour urine based creatinine clearance measurements are time consuming and inaccurate, the parameter most often used to estimate renal function in clinical practice is the serum creatinine concentration. An isolated serum creatinine concentration is unsatisfactory for this purpose as it depends on creatinine production, which is related to muscle mass, as well as on renal elimination of
Abstract. Background: Serum cystatin C, a cysteine protease inhibitor, has been suggested as a new marker of glomerular filtration rate (GFR). This study explored the possibility of replacing the creatinine clearance (CrCl) estimation of GFR with cystatin C in early detection of renal impairment in cancer patients on chemotherapy.
However, measuring creatinine clearance is time-consuming and fraught with errors of timing and collection, so other methods of estimating GFR, both those that rely on determining serum creatinine levels and those that do not, have been sought to replace the measured creatinine clearance.
Mean serum creatinine, C Cr, and urine creatinine at the 5 time points are shown in table 2 and normalized values are shown in figure 1. As expected, serum creatinine …
A formula has been developed to predict creatinine clearance (Ccr) from serum creatinine (Scr) in adult males: (see article)(15% less in females). Derivation included the relationship found
Since almost all urinary creatinine is derived from the muscle mass, the amount of creatinine in the urine will be proportional to muscle mass, and it will show an almost constant decrease with age. A simple equation for estimating creatinine clearance has been derived. For women the creatinine
The correlation between creatinine clearance measured and creatinine clearance predicted using serum creatinine from the same subject group was high (r=0.882). A nomogram for creatinine clearance prediction was derived from an equation that included the logarithmic transformation of age, body weight, height, and creatinine excretion instead of the original, nonlogarithmic values.
Albuminuria, elevated serum creatinine and low estimated glomerular filtration rate (eGFR) are pivotal indicators of kidney decline. Yet, it is uncertain if these and emerging biomarkers such as uric acid represent independent predictors of kidney disease progression or subsequent outcomes among individuals with type 2 diabetes mellitus (T2DM).
The accuracy of the formulae, which are all based on serum creatinine, is dependent on the reliability of the creatinine measurement. We do not have complete information regarding the method used to measure creatinine for the different formulae ( Table 1 ).
Although attempts have been made to validate certain renal function prediction equations among patients with chronic kidney disease (CKD) with abnormal serum creatinine levels, this is the first study to specifically evaluate the predictive performance of these equations for patients with CKD and serum creatinine levels in the normal range.

Serum creatinine is the result of generation, distribution and excretion of creatinine; a lower generation will therefore result in a lower serum concentration for the same GFR, if distribution and excretion remain the same. Serum creatinine is produced by non-enzymatic hydrolysis of creatine, the major sources of this creatine being the release from endogenous muscles and exogenous
