Three surveys were organized in the Rotterdam area with respect to the determination of total bilirubin in neonatal sera. Fifteen hospital laboratories participated. The coefficients of variation dropped from about 15% (survey 1) to about 8% (survey 3). This improvement was reached by discussing the techniques used, and in some cases by changing them.
