Serum cholesterol levels from birth to maturity.

Normal values for serum levels of total cholesterol, and of low-density and high-density lipoprotein cholesterol from a longitudinal study of children from birth to two years of age, and from cross-sectional studies of four-year-old children, schoolchildren aged from eight to 18 years, and the young adult parents of the two-year-old children are reported. These data will provide a reference range for the normal Australian youth population, and cut-off points in the identification of hypercholesterolaemia.
