What are the units for eGFR?

What are the units for eGFR?

eGFR stands for ‘estimated Glomerular Filtration Rate.

Your eGFR is reported in millilitres per minute which is written as mL/min/1.73m2 (the “1.73m2” indicates a result expressed relative to body surface area).

If your result is over 60 mL/min/1.73m2, your kidney function is normal or close to normal.

What is the formula for glomerular filtration rate?

It is defined as the sum of the filtration rates of all your functioning nephrons (filtering units making up the kidneys). An estimate of the normal value for your GFR can be obtained by using the equation: GFR = 140 – [your age].

What is eGFR CKD EPI?

The CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) equation was developed in an effort to create a more precise formula to estimate glomerular filtrate rate (GFR) from serum creatinine and other readily available clinical parameters, especially at when actual GFR is >60 mL/min per 1.73m2.

What is normal GFR CKD EPI?

A GFR of 60 or higher is in the normal range. A GFR below 60 may mean kidney disease. A GFR of 15 or lower may mean kidney failure.

What is normal GFR CKD-EPI?

What is eGFR CKD-EPI?

Is GFR 120 normal?

According to the National Kidney Foundation, normal results range from 90 to 120 mL/min/1.73 m2. Older people will have lower than normal GFR levels, because GFR decreases with age.

How do you calculate the CKD-EPI equation?

The CKD-EPI equation, expressed as a single equation, is: GFR = 141 * min(Scr/κ,1) α * max(Scr/κ, 1) -1.209 * 0.993 Age * 1.018 [if female] * 1.159 [if black] Scr is serum creatinine (mg/dL), κ is 0.7 for females and 0.9 for males, α is -0.329 for females and -0.411 for males, min indicates the minimum of Scr/κ or 1,…

What does CKD-EPI stand for?

CKD-EPI Calculator for Adults (SI Units) In adults, the most widely-used equations for estimating glomerular filtration rate (GFR) from serum creatinine are the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation 1 and the isotope dilution mass spectrometry (IDMS) traceable Modification of Diet in Renal Disease (MDRD)

How do you calculate eGFR from ECKD?

CKD-EPI Creatinine Equation (2009) eGFR = 141 x min(S Cr /κ, 1) α x max(S Cr /κ, 1) -1.209 x 0.993 Age x 1.018 [if female] x 1.159 [if Black]

When should the CKD-EPI calculator be used for the diagnosis of GFR?

*This equation should only be used for patients 18 and older. **The NIDDK presently recommends using the CKD-EPI calculator for reporting estimated GFR values greater than or equal to 60 mL/min/1.73 m². 1. Levey AS, Stevens LA, Schmid CH, Zhang YL, Castro AF, 3rd, Feldman HI, et al.
