2017-09-07 · CrCl = [(140 - age) x IBW] / (Scr x 72) (x 0.85 for females) Note: if the ABW (actual body weight) is less than the IBW use the actual body weight for calculating the CRCL. Estimate Ideal body weight in (kg) 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.
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?
The results you receive from this tool are for informational purposes only and should not be the basis of your medical decision making. 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. 12 Existing guidance from the BNF advises prescribers to use calculated CrCl rather than eGFR when initiating or adjusting dose in people taking nephrotoxic drugs, elderly patients, and patients at The MHRA, in line with the British National Formulary (BNF), has suggested that calculated CrCl (using the Cockcroft-Gault formula) should be considered for people taking nephrotoxic drugs (eg, amphotericin B and vancomycin), older people (aged ≥75 years) and those at extremes of muscle mass (body mass index <18 or >40 kg/m 2).1 2 In addition, CrCl should be considered for adjusting the dose of medicines that are substantially renally excreted and have a narrow therapeutic index (eg Further, this formula does not correct for race. It is known that African Americans have a higher muscle mass than Caucasians; hence, African Americans will have a higher serum creatinine level at any level of creatinine clearance.
4) Do not use estimated glomerular filtration rate (eGFR) which may overestimate renal clearance, especially in elderly patients with low body weight/ body mass index. Chromium chloride (CrCl4), (T-4)- | CrCl4 or Cl4Cr | CID 177612 - structure, chemical names, physical and chemical properties, classification, patents, literature CRCL is calculated on the basis of a properly defined equation called the Cockcroft-Gault Equation. To calculate CRCL, you need to use a dependable calculator designed for this purpose. CRCL is calculated on the basis of multiple input parameters including sex, weight, age and creatinine. The British National Formulary (BNF) is a United Kingdom (UK) pharmaceutical reference book that contains a wide spectrum of information and advice on prescribing and pharmacology, along with specific facts and details about many medicines available on the UK National Health Service (NHS).
