for calculating the CCr from the serum creatinine Cr is that put forth by Cockcroft and Gault (Nephron 1976, 16: 31–41): male CCr = (body weight [kg] ∞ (140-age)) divided by (72 ∞?Cr [mg/100 ml]); female CCr = 0.85 ∞ above; → see also clearance, glomerular filtration ...
you may be asked to collect your urine over a 24-hour period in a container provided by your health care team for a creatinine clearance test. This method is inconvenient and not commonly used anymore, but it may still be
(a) Using the Cockcroft-Gault formula (Eqn(1)) which predicts thecreatinine clearancefromserum creatinine. In this method, the age of the patient is considered to be fixed as 73 for male and 85 for females (which is substituted for “A” in equation(1)). ...
The routine laboratory findings were within the normal limits. It should be underlined that serum creatinine was on average below 1.5mg/dl, while the value of the calculatedcreatinine clearancewas almost 30ml/min, using the Cockcroft-Gault formula. The levels of creatinine clearance found incentenari...

clearance was a "simple" resident research project designed by Dr. Henry Gault, my mentor at the time. We set out to evaluate the accuracy of a creatinine clearance nomogram bySiersbaek-Nielsen (1971). Our data, almost identical to that used to create the nomogram, resulted in our formula...
The creatinine clearance can be measured in two ways: It can be calculated (estimated) by a formula using serum (blood) creatinine level, patient's weight, and age. The formula is 140 minus the patient's age in years times their weight in kilograms (times 0.85 for women), divided by 72...
In addition, creatinine clearance was calculated by use of the Cockcroft–Gault formula. Serum creatinine levels were lower in patients with CF than in 19 age-matched healthy controls, but serum cystatin C level and iothalamate-measured GFR were both similar in the two groups. Cystatin C-...
Body surface area indexed (BSA-indexed) eGFR-Cr and eGFR-Cys were calculated based on the following formula: eGFR-Cr (mL/min/1.73 m2) = 194 × (serum Cr)−1.094 × (age)−0.287(× 0.739, when female)16, and eGFR-CysC (mL/min/1.73 m2) = 104 × (ser...
This most likely reflects the low population prevalence of CKD in these age groups, as the validation data were obtained from consecutive referrals for clearance measurements. Still, the 493 children with mGFR <60 ml/min per 1.73 m2 in the present study is far more than the 168 children ...
