Reference value for cord blood lipid and lipoprotein concentrations. Acta Paediatr Scand, 63: 431, 1974.–Cord blood lipid and lipoprotein concentrations in 120 newborns, 60 boys and 60 girls, have been determined in order to evaluate reference values for these components. The lipoprotein analyses were performed with an electrophoretic technique, which enables correction for the difference in lipid composition of the lipoproteins in the quantitation procedure. The lipid analyses revealed a small, but statistically significant higher phospholipid concentration in girls than in boys ( p <0.05). A similar difference in cholesterol concentration was not statistically significant ( p >0.05). No sex difference was found in lipoprotein concentrations. Our results were generally found in accordance with the few other previous studies on lipoproteins in cord blood. The results were also directly comparable to those in a recent study on the LDL‐cholesterol concentration in cord blood (12). This supports the assumption that the lipoprotein composition in newborns is similar to that found in adults. The distribution of the cord blood lipid and lipoprotein concentrations in the sample are given, and by use of non‐parametric statistics the contidence intervals for the true percentiles in the population were calculated.
