Program is based on the following equations:

Schwartz equation:      CrCl (ml/min/1.73m2)=  [length (cm) x k] / Scr
(Patient population: infants over 1 week old through adolescence (18 years old))
k = 0.45 for infants 1 to 52 weeks old
k = 0.55 for children 1 to 13 years old
k = 0.55 for adolescent females 13-18 years old
k = 0.7 for adolescent males 13-18 years old
