This calculator includes inputs based on race which may or may not provide better estimates so we have decided to make race optional. If you have an eGFR value calculated by a local laboratory use that.
Estimated Glomerular Filtration Rate Gfr Calculator
When your eGFR is calculated by your doctor weight and body size may also be factored into your eGFR.

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.
GFR 175 S Cr-1154 age-0203 0742 if female 1212 if Black where S Cr serum creatinine in mgdL. Your GFR tells your doctor your stage of kidney disease and helps the doctor plan your treatment. EGFR 175 creatinine 0011312-1154 age-0203 1212 if afro carribean race 0742 if female Notes eGFR is the preferred NHS measure of renal function but will give unreliable estimates in acute renal failure as will serum creatinine.
EGFR calculator eGFR stands for estimated Glomerular Filtration Rate. All laboratories should be using creatinine methods calibrated to be IDMS traceable. EGFR is calculated from blood test results using a formula that looks at the level of creatinine a waste product in your blood.
MLmin173 m 2 Age Race Gender Plasma creatinine Chronic kidney disease GFR less than 60 or kidney damage for at least three months All ethnic groups other than African American NOTE. Calculator above uses the abbreviated MDRD equation. Estimating GFR begins with a simple serum creatinine blood test.
EGFR Bedside Schwartz Formula 413 mLmin173 m2 4 year old male. K 045 in term infants to 1 year of age. GFR Calculator for Adults.
Estimated GFR Glomerular Filtration Rate by MDRD. Bedside IDMS-traceable Schwartz GFR Calculator for Children. For the same creatinine value this calculator estimates a higher GFR for Black patients.
The National Kidney Foundation recommends using the CKD-EPI Creatinine Equation 2009 to estimate GFR. K 055 in children to 13 years of age. - The GFR 041 Heightin cm S Cr.
See here for more on our approach to addressing race and bias on MDCalc. EGFR - Estimated glomerular filtration rate is the best test to measure your level of kidney function and determine your stage of kidney disease. EGFR k x height in cm serum Cr.
EGFR 041 x height in cm serum Cr. Estimated GFR for children using Schwartz formula. GFR Calculators for Adults for patients 18 and older In adults recommended equations for estimating glomerular filtration rate GFR from serum creatinine include the Modification of Diet in Renal Disease MDRD Study equation IDMS-traceable version and the Chronic Kidney Disease Epidemiology Collaboration CKD-EPI equation.
186 x Creatinine884-1154 x Age-0203 x 0742 if female x 1210 if black. Normal GFR varies according to age sex and body size and declines with age. GFR is measured in mLmin173m 2.
Module 707 eGFR is estimated GFR calculated by the abbreviated MDRD equation. This calculator is for people aged 18 years or older. CLICK HERE FOR THE CURRENT PEDIATRIC CALCULATOR.
For comparison purposes the results for three prevalent formulas used for estimating GFR are provided. See here for more on our approach to addressing race and bias on MDCalc. Your doctor can calculate it from the results of your blood creatinine test your age body size and gender.
Related to the optimal GFR level the 60mLmin173m 2 level is adequate. 1 inch 254 cm. Glomerular filtration rate GFR is the best overall index of kidney function.
The below section of this page provides you the online eGFR calculator in which the GFR by MDRD is estimated based on the inputs such as gender skin race of the patient creatinine level and age. The estimated GFR values above 60 mLmin173 m2 should be interpreted as above 60 mLmin173 m 2 not an exact number. GFR 0413 heightin cm S Cr.
For the same creatinine value this calculator estimates a higher GFR for Black patients. EGFR can also be calculated by using the eGFR calculator below. If youre using our GFR calculator your eGFR is calculated using the results of your blood test along with your age ethnicity and gender.
For example to calculate the eGFR of a female whose age is 35 years and the serum creatinine levels are 11 use the IDMS Traceable MRD study equation. 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. The GFR glomerular filtration rate Calculator estimates GFR values based on factors including serum creatinine value age race and gender.
In case of children it is used the Schwartz formula. K 070 in adolescent males females remain at 055 after age 13 years IDMS-Traceable Schwartz Equation. Results consistently below 60mLmin173m2 indicate chronic kidney disease.
This calculator includes inputs based on race which may or may not provide better estimates so we have decided to make race optional. When the childs height is expressed in inches the height should be converted from inches to centimeters.
