To determine whether arterial and capillary values for bilirubin agree in neonates, we analyzed 35 simultaneously sampled capillary and arterial specimens from 13 infants. We found a high correlation between arterial and capillary bilirubin values (r = 0.993). We conclude that arterial bilirubin samples may be substituted for capillary samples in newborn infants.
