540 healthy employees were examined by a clinicochemical analyzer "PA-1000, Technicon", enzyme methods and calculated ratio. With the help of a non-parametric method the reference ranges (0.025 and 0.975 fractiles) and their 90% confidence intervals were determined for serum triglycerides (0.49-0.60 and 2.60-2.79), total cholesterol (3.18-3.49 and 6.92-7.43), high density lipoprotein cholesterol (0.68-0.78 and 2.00-2.20), low density lipoprotein cholesterol (1.56-1.71 and 4.83-5.31)-im mmol/l and the ratio total cholesterol: high density lipoprotein cholesterol (2.21-2.48 and 6.56-7.15). 0.25, 0.50 and 0.75 fractiles are also pointed out and the analytical control, the time of the test, sex and age differences as well as the risk degree of atherosclerosis are discussed.
