The full Schwartz pediatric eGFR calculation requires height, serum creatinine, cystatin C, blood urea nitrogen and gender.
The original Schwartz eGFR formula was devised in the mid-1970s to estimate GFR in children. This model was felt to overestimates GFR, likely a result of a change in methods used to measure creatinine.
In 2009, Schwartz et al developed a revised estimated GFR formula using data from cohort of children in the Chronic Kidney Disease in Children (CKiD) study.
This model is appropriate for children between the ages of 1 to 16 yr.
The linear regression analyses generated a model that included the following:
The full equation is as follows:
Given the complexity of this formula, a "bedside" version requiring only height and creatinine was developed:
eGFR = 0.413 X (height/serum creatinine),
where height is in cm, and
creatinine is in mg/dL
