Estimation of normal ranges for various biochemical parameters.

Frequency distributions of ten biochemical parameters are reported for a sample (40000 events) of the populations of Milano. Average values and standard deviations have been calculated for the female and male populations, subdivided in four classes of age. The values of the parameters increase with age; generally, except in the case of the rate of sedimentation, the values for the female population are lower with respect to those for the male population.
