Some physiological reasons, particularly its dependence on muscle mass makes sCr an imperfect biomarker of GFR. Muskelmassan hos individen påverkar dock koncentrationen av kreatinin i plasma, varför matematiska formler har tagits fram for att kunna skatta GFR från kreatinin med beaktande av ålder, kön och i vissa fall etnicitet, vikt och längd. The plasma creatinine concentration (P CR) is a simple and useful correlate of GFR. Plasma creatinine is an inexpensive and widely used test of kidney function; when it is repeated serially in an individual, it may give significant insight into changes in kidney function. GFR is a calculation that takes into account creatinine levels, along with age, gender, race, and weight. The GFR can be an indicator of renal disease.

Glomerular filtration rate. Fluid management as well as dosage regimens of drugs in preterm newborn infants should be  Mar 6, 2012 An introduction to Creatinine and GFR to assist you in solving problems in clinical medicine.

Because of variability in serum creatinine from one person to another, the GFR may provide a more accurate reading on kidney function. Creatinine is removed from plasma by glomerular filtration into the urine without being reabsorbed by the tubules to any significant extent. Renal tubular secretion also contributes a small quantity of creatinine to the urine. As a result, creatinine clearance often overestimates the true glomerular filtration rate (GFR) by 10% to more than 20%. Like all other creatinine-based estimation equations, they suffer from physiologic limitations of creatinine as a filtration marker. 4, 7 The terms for age, sex, and race in both equations only capture some of the non-GFR determinants of creatinine concentration in blood plasma, and the coefficients represent average effects observed in the Causes of an increased plasma/serum urea and creatinine concentration Renal causes. Both plasma urea and plasma creatinine concentration are raised if glomerular ­filtration rate (GFR), that is renal function, is significantly reduced.

glomerular filtration rate

Although reduced GFR (i.e. renal disease) is also associated with increased plasma urea concentration, there are other non-renal conditions that can give rise to increased plasma urea.
