Pottel et al reported a model for estimate the glomerular filtrate rate (eGFR) over a full range of ages. The authors are from multiple authors from Europe, America and Brazil.
Parameters:
(1) age in years
(2) sex
(3) serum creatinine in µmol/L
estimated GFR in mL per min per 1.73 square meters =
= (107.3 / ((serum creatinine) / Q)) * (age factor) =
= (107.3 * Q * (age factor)) / (serum creatinine)
