Height (cm): Typical creatinine clearance for healthy persons are
Weight (kg):
Age Male Female
(Years) (ml/min/1.73 m2) (ml/min/1.73 m2)
<10 70 - 140 70 - 140
10 - 49 85 - 160 75 - 156
50 - 59 77 - 144 68 - 140
60 - 69 69 - 130 61 - 126
>=70 62 - 120 55 - 114
Urine creatinine (µmol/l):
Urine volume (ml):
Urine collection time (hours):
Serum creatinine (µmol/l): (8.5 - 1300)
Body Surface Area ( m2 ) =
Creatinine clearance (ml / min/1.73 m2) =

A creatinine determination on both serum and a 24 hr collection of urine is required.
The laboratory will report urine creatinine in µmol / 24 hr.

A creatinine determination on both serum and a timed collection of urine is necessary.

BSA (m2) = 0.0235 x Height (cm)0.42246 x Weight (kg)0.51456 (The Gehan and George formula)
(The Gehan and Geogre formula is used in the calculation in the calculator above)
(ref: http://perso.club-internet.fr/alaffont/compute/bsa/gehan/gehan.htm)

Creatinine Clearance (ml / min) = (Urine Creatinine / Serum Creatinine) x (Urine Volume (ml) / [ time (hr) x 60 ] )* ( 1.73 / Body Surface Area)

Other body surface area formulas are:

The Lam and Leung formula:
BSA (m2) = 0.007184 x Height (cm) 0.725 x Weight (kg) 0.425
 
The Haycock formula:
BSA (m2) = 0.024265 x Height (cm)0.3964 x Weight (kg)0.5378
(ref: http://perso.club-internet.fr/alaffont/compute/bsa/haycock/haycock.htm)
The Mosteller formula:
BSA (m2) = [ Height(cm) x Weight (kg) / 3600] ½ or BSA (m2) = [ Height(inch) x Weight (pound) / 3131] ½
