In a new study, Schwartz and colleagues have investigated the best way to estimate glomerular filtration rate (GFR) in children. Having already improved GFR estimation with the use of creatinine-based equations, the investigators now propose a more precise method for cystatin C measurement. The precision of a GFR equation will strongly depend on the analytical precision of the biological variables included.
