How do you calculate GFR from creatinine?
The equations are as follows:
- For female with creatinine < 62 µmol/L: eGFR (mL/min/1.73m2) = 144 x (Cr/61.6)-0.329 x (0.993)Age
- For female with creatinine > 62 µmol/L: eGFR (mL/min/1.73m2) = 144 x (Cr/61.6)-1.209 x (0.993)Age
- For male with creatinine < 80 µmol/L: eGFR (mL/min/1.73m2) = 141 x (Cr/79.2)-0.411 x (0.993)Age
What is the formula to calculate GFR?
The CKD-EPI equation, expressed as a single equation, is: GFR = 141 * min(Scr/κ,1)α * max(Scr/κ, 1)-1.209 * 0.993Age * 1.018 [if female] * 1.159 [if black]
How is creatinine calculated?
Creatinine Clearance Calculator Creatinine Clearance = [[140 – age(yr)]*weight(kg)]/[72*serum Cr(mg/dL)] (multiply by 0.85 for women).
What is GFR and how is it calculated?
What is estimated GFR? Your estimated glomerular filtration rate (eGFR) is the calculation that indicates your level of kidney function, based on the results of a creatinine serum test and other factors—such as age, gender, muscle mass, and ethnicity.
Why is creatinine used to measure GFR?
As your body makes it, it’s filtered through your kidneys and expelled in urine. Your kidneys’ ability to handle creatinine is called the creatinine clearance rate, and this helps estimate how fast blood is moving through your kidneys, called the glomerular filtration rate (GFR).
Is creatinine clearance same as GFR?
Creatinine clearance ( CrCl ) is an estimate of Glomerular Filtration Rate ( GFR ); however, CrCl is slightly higher than true GFR because creatinine is secreted by the proximal tubule (in addition to being filtered by the glomerulus).
Why is creatinine used to estimate GFR?
When do you use GFR vs CrCl?
Creatinine clearance ( CrCl ) is an estimate of Glomerular Filtration Rate ( GFR ); however, CrCl is slightly higher than true GFR because creatinine is secreted by the proximal tubule (in addition to being filtered by the glomerulus). The additional proximal tubule secretion falsely elevates the CrCl estimate of GFR .
Does GFR equal creatinine clearance?
Creatinine Clearance ( CrCl ) versus Glomerular Filtration Rate ( GFR ) Creatinine clearance ( CrCl ) is an estimate of Glomerular Filtration Rate ( GFR ); however, CrCl is slightly higher than true GFR because creatinine is secreted by the proximal tubule (in addition to being filtered by the glomerulus).
What is eGFR creatinine?
What is eGFR? eGFR (estimated glomerular filtration rate) is a measure of how well your kidneys are working. Your eGFR is an estimated number based on a blood test and your age, sex, body type and race. eGFR is considered a mostly reliable test for doctors to know how well your kidneys are working.
What is the formula to calculate the GFR?

How to calculate GFR manually?
GFR is measured in mL/min/1.73m 2. In case of children it is used the Schwartz formula: – The GFR = 0.41 * Height(in cm) / S Cr. When the child’s height is expressed in inches, the height should be converted from inches to centimeters: 1 inch = 2.54 cm. Related to the optimal GFR level, the 60mL/min/1.73m 2 level is adequate.
How to calculate glomerular filtration rate?
– The results of a blood test that measures creatinine, a waste product filtered by the kidneys – Age – Weight – Height – Gender – Race
What is a good number for GFR?
– Have a family history of kidney disease. – You’re over 60 years of age. – You’re african american, Hispanic, asian or american indian. – Have diabetes. – Have high blood pressure.
