What is the Cockcroft-Gault equation used for?
Calculates CrCl according to the Cockcroft-Gault equation. For use in patients with stable renal function to estimate creatinine clearance. Can be used to estimate kidney function for CKD staging.
What is the GFR equation?
| Race | Sex | Equation (age in years for ≥ 18) |
|---|---|---|
| White or other | Female | GFR = 144 × (Scr/61.9)-0.329 × (0.993)Age |
| White or other | Female | GFR = 144 × (Scr/61.9)-1.209 × (0.993)Age |
| White or other | Male | GFR = 141 × (Scr/79.6)-0.411 × (0.993)Age |
| White or other | Male | GFR = 141 × (Scr/79.6)-1.209 × (0.993)Age |
What is 140 in Cockcroft-Gault formula?
The Cockcroft-Gault formula reads: GFR estimate = (140 − age (years) × weight (kg) × constant/serum creatinine(μmol/L)The published constants are 1.23 for males of any age, and 1.05 for females of any age[4].
What is normal GFR?
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.
How do you read GFR results?
How is ClCr calculated?
Creatinine Clearance (ClCr): Estimate using the Cockcroft-Gault equation: ClCr (mL/min) = 1.2 (140 – age) (weight in kg) Serum creatinine (µmol/L) For females, multiply result by 0.85.
What is modified Cockcroft-Gault?
A modified Cockcroft-Gault formula taking into account the body surface area gives a more accurate estimation of the glomerular filtration rate. J Nephrol.
What is a normal GFR level for one kidney?
An estimated glomerular filtration rate (eGFR) of 56 milliliters per minute per 1.73 meters squared is normal for a single kidney. The two kidney normal is between 90 and 120.
What is normal GFR for age?
The normal range of Kidney Glomerular Filtration Rate is 100 to 130 mL/min/1.73m2 in men and 90 to 120mL/min/1.73m2 in women below the age of 40. GFR decreases progressively after the age of 40 years….GFR Number by Age.
| Estimated GFR Number by Age Group | |
|---|---|
| Age | Mean Estimated GFR (mL/min/1.73 m2) |
| 20-29 | 116 |
| 30-39 | 107 |
| 40-49 | 99 |
What weight should I use for Cockcroft-Gault?
Cockcroft and Gault equation utilizing the ibw (Ideal body weight) to calculate an estimated creatinine clearance. actual body weight for calculating the CRCL. Males: IBW = 50 kg + 2.3 kg for each inch over 5 feet. Females: IBW = 45.5 kg + 2.3 kg for each inch over 5 feet.
What is GFR CKD EPI?
CKD-EPI GFR. The CKD-EPI GFR is an estimate of the glomerular filtration rate (GFR) using serum creatinine and demographic factors. It is a relatively new equation proposed to be superior to the MDRD GFR equation.
What is GFR MDRD?
The MDRD GFR is an estimate of the glomerular filtration rate (GFR) using serum creatinine and demographic factors. It has not been studied extensively in populations that are not white or black. It relies on a stable creatinine and may be less accurate for GFR values above 60.
What is GFR non African American?
eGFR for African American & non-African American. GFR (glomerular filtration rate) is equal to the total of the filtration rates of the functioning nephrons in the kidney , it is usually accepted as the best overall index of kidney function.
Is GFR creatinine clearance?
Creatinine clearance and GFR are different, but often (incorrectly) used interchangeably. Technically, creatinine clearance is a surrogate for GFR (glomerular filtration rate), but creatinine clearance slightly overestimates GFR.
