Creatinine Clearance, Body Surface Area BSA, Dosing Weight Calculator

**IBW(male)** = 50 kg + 2.3 kg x (# inch over 5 ft) OR 50kg + 0.9 kg x (# cm over 150cm)
**IBW(female)** = 45.5 kg + 2.3 kg x (# inch over 5 ft) OR 45.5kg + 0.9 kg x (# cm over 150cm)
**Dosing Weight** = IBW + 0.4(actual weight - IBW) (calculated only if actual weight is > 20% more than IBW)
**CrCl** = (140-Age)x1.2xWeight (Kg)/Serum Cr(umol/L) (x 0.85 for female).
**Note:** when height is not available, actual body weight is used instead of IBW which will give less accurate estimation of CrCl. If only height is entered, IBW will be calculated.
**Body Surface Area (BSA) DuBois** = 0.20247 x Height(m)^0.725 x Weight(kg)^0.425(m²)
**BSA (Mosteller)** = ( [Height(cm) x Weight(kg) ]/ 3600 )^½
**BSA (Haycock)** = 0.024265 x Height(cm)^0.3964 x Weight(kg)^0.5378
**BSA (Gehan/George)** = 0.0235 x Height(cm)^0.42246 x Weight(kg)^0.51456
**BSA (Boyd)** = 0.0003207 x Height(cm)^0.3x Weight(grams)^{(0.7285 - (
0.0188 x LOG(grams) )}
