Calculates an estimate of glomerularfiltrationrate from patient's age and serum creatinineconcentration.Calculated using the Cockcroft and Gault formula: (140 − Age)×Weight × Constant/ Serum creatinine.Male constant = 1.23, Female constant = 1.04.Tested against the BNF online calculator.
Calculate a patient's body surface areausingthe Dubois formula:Body Surface area (m^2) = 0.007184 × (patient height incm)^0.725× (patient weight in kg)^0.425.Tested against the BNF online calculator.
