Abstract
Serum creatinine concentrations were studied in 52 healthy, full-term infants (29 males and 23 females) during the first five days of life. At birth, mean serum creatinine concentration was 0.76 ± 0.13 mg/dL. At 6 hours of life, values increased to 0.97 ± 0.11 mg/dL (P < 0.001) and remained elevated for 24 hours. Values then returned to baseline so that serum creatinine concentrations were 0.81 ± 0.15 mg/dL at 48 hours and 0.6l ± 0.15 mg/dL at 3 to 5 days of age. At birth, serum creatinine concentrations were higher in males than in females (0.80 ± 0.13 versus 0.71 ± 0.11 mg/dL, respectively; P < 0.009). However, the increases in serum creatinine concentration observed after birth were similar in both sexes. This is the first report of a prospective longitudinal study of serum creatinine concentrations between birth and 3 to 5 days of age in a Hispanic population. In addition, data were analyzed by sex. The results are a useful reference for normal serum creatinine concentrations in early life.
