Sumario:OBJECTIVE: The purpose of this study was to determine the levels of Cystatin C in healthy term newborns in the first month of life. INTRODUCTION: Cystatin C may be a suitable marker for determining the glomerular filtration rate because it is not affected by maternal renal function. METHODS: Cohort study. Inclusion: term newborns with appropriate weight; mother without renal failure or drugs that could affect fetal glomerular filtration rate. Exclusion: malformations; hypertension or any condition that could affect glomerular filtration rate. Cystatin C (mg/L)and creatinine (rng/dl) were determined in the mother (Mo) and in the newborn at birth (Day-0), 3rd (Day-3), 7th(Day-7) and 28t>h(Day-28) days. Statistics: one way ANOVA and Pearson's correlation tests. Sample size of 20 subjects for a = 5% and a power test = 80% (p
