Reference intervals for serum lipids, lipoproteins, and apoproteins in the elderly.

We measured total cholesterol, high-density-lipoprotein cholesterol, low-density-lipoprotein cholesterol, triglycerides, apoprotein A, and apoprotein B in serum. The subjects were a volunteer group of 145 white people (50 men and 95 women) ranging in age between 65 and 95 years, who were not receiving medical treatment and had no disease that could influence lipid metabolism. Before further categorization, we saw no significant sex-related difference in any of these lipid constituents.
