Estimated GFR mlmin173m 2 186 x Creat 884 -1154 x Age -0203 x 0742 if female x 1210 if black Serum creatinine is correlated with muscle mass and therefore estimation of GFR using prediction equations in people with extremes of muscle mass is subject to inaccuracy. Hereof what is GFR and how is it calculated.

GFR calculates your age serum creatinine number and gender to produce a score. GFR is a test used to check how well the kidneys are working. Glomerular filtration rate GFR is the best overall index of kidney function. If values for cystatin C andor BUN are not entered the calculator will generate GFR estimates using the creatinine-based Bedside Schwartz equation only currently considered the best method for estimating GFR in children.

View more on it here. For the purposes of drug dosing or estimating GFR in patients with body size that is very different than average GFR can be non-normalized using the following equation. Completely healthy kidney function is measured at a glomerular filtration rate GFR of around 100 which means that the kidneys are working at 100 percent. EGFR is the preferred NHS measure of renal function but will give unreliable estimates in acute renal failure as will serum creatinine.

Normal kidney function but urine findings or structural abnormalities or genetic trait point to kidney disease. So if your eGFR is 50 your kidneys are probably filtering at about 50 of normal.

EGFR is an estimate of how well your kidneys are filtering. A large simulation study compared eGFR by MDRD Study equation and estimated creatinine clearance eCrCl by the Cockcroft-Gault equation calculated from standardized creatinine values to each other and to measured GFR for the purpose of drug dosing. It is likely to be more accurate than this calculator which cannot take into account local variations in creatinine measurements. Your GFR tells you how much kidney function you have.

Determining your GFR levels requires a simple blood test. For persons 18 and older use the GFR calculator for adults. Currently the best equation for estimating glomerular filtration rate GFR from serum creatinine in children is the Bedside Schwartz equation for use with creatinine methods with calibration traceable to IDMS 1 2. Glomerular Filtration Rate GFR is the measurement used to determine kidney function.
