Abstract:
PURPOSE: Bilirubin values may vary depending on the site of sampling. The purpose of this study is to compare simultaneously obtained capillary and venous serum bilirubin to assess neonatal jaundice. METHODS: The subjects for the study included 135 healthy inborn as well as outborn full-term infants admitted to Dong-Eui Medical Center for evaluation of jaundice from May 1997 to February 1999. A paired capillary and venous sample was simultaneously drawn from each neonate, and their serum bilirubins were measured by direct spectrophotometric method. RESULTS: A high correlation between capillary and venous serum bilirubin(correlation coefficient(r) =0.949, P<0.05) was observed. No significant difference between mean capillary and venous bilirubin was detected when capillary bilirubin was less than 10 mg/dL(P>0.05), however, the mean venous bilirubin was significantly higher than the mean capillary bilirubin(mean difference;0.65+/-1.04 mg/dL, P<0.0001) when the capillary bilirubin was greater or equal to 10 g/dL(P>0.05). CONCLUSION: There was a trend toward venous bilirubin being higher than capillary bilirubin at higher serum bilirubin levels. However, further studies are needed to ascer-tain the relationship between the site of the sampling and methodology in measurement of bilirubin.
