# For children, the best estimate is obtained from the cystatin C-based estimating equation alone6. Calculating robust estimates of relative GFR. The level of cystatin

The Cockcroft and Gault formula (1973) C Cr ={((l 40–age) x weight)/(72xS Cr)}x 0.85 (if female) Abbreviations/ Units. C Cr (creatinine clearance) = mL/minute. Age = years. Weight = kg. SCr (serum creatinine) = mg/dL. Why is the Cockcroft-Gault formula provided on this website?

Estimate Ideal body weight in (kg) The C-G formula is dependent on age as its main predictor for CrCl. Below is the formula: eCCr = (140 – Age) x Mass (kg) x [0.85 if female] / 72 x [Serum Creatinine (mg/dL)] CKD-EPI Equation 13: Cr in (mg/dL): eGFR = 141 x min (SCr/κ, 1) α x max (SCr /κ, 1) -1.209 x 0.993 Age x 1.018 [if female] x 1.159 [if Black] κ = 0.7 (females) or 0.9 (males); α = -0.329 (females) or -0.411 (males) min = indicates minimum of SCr/κ or 1; max = indicates maximum of SCr/κ or 1. GFR = [UCr x V] / SCr This formula is called the creatinine clearance and tends to exceed the true GFR by 10 to 20 percent or more depending upon the proportion of urinary creatinine that is derived from tubular secretion [ 4 ]. Historically, this error was balanced by an error of almost equal magnitude in the measurement of the serum creatinine.

In case the serum creatinine is given in mg/dL, the conversion from mg/dL to µmol/L is: 1 mg/dL = 88.4 µmol/L. CrCl normal values are around 97-137 ml/min in men and 88-128 mL/min in women. Creatinine Calculator Formula: CRCL = (140 - A) * W * r /(72 * C) Where: A: Age, in years W: Body weight, in pounds (lbs) C: Serum Creatinine Level, in mg/dL r: Sex difference ratio, 0.85 for woman, and 1 for man CrCl or GFR: Most appropriate method for drug dosing: 30 mL/min The Cockcroft-Gault equation is the gold standard for estimating renal function for the purposes of drug dosing. Because this patient is obese (BMI ≥ 30 m 2 or > 25% ideal body weight), the Cockcroft-Gault (with 40% adjustment) method should be used.

CrCl =.

## The normal range of GFR, adjusted for body surface area, is 100–130 average 125 (mL/min)/(1.73 m2) in men and 90–120 (mL/min)/(1.73 m2) in women younger than the age of 40. In children, GFR measured by inulin clearance is 110 (mL/min)/(1.73 m2) until 2 years of age in both sexes, and then it progressively decreases.

Cl 67.2%. Cr 32.8%. Definitions. Chemical Formula: is a way of presenting information about the chemical Where: Gender value is 0 for men and 1 for women; BSA DuBois’s formula = 0.007184 x (Height in cm) 725 x (Weight in kg) 0.425.

### One of the limitations of the Cockcroft-Gault formula is that it overestimates creatinine clearance at low levels of renal function, particularly in nursing home
