Cross-Sectional Assessment of Laboratory Variables in a Healthy Male Population

Abstract

The statistical analysis of 29 laboratory variables with five decade age groups shows statistical differences between cigarette smokers and nonsmokers in serum alpha-2 and gamma globulin in fractions over multiple age groups, and hemoglobin, hematocrit, phosphorus, urine reaction, total bilirubin, and WBC in random age groups. Cholesterol level, although having a slightly lower mean and falling off at a later age in nonsmokers, is not statistically different from the smokers. It would appear that cigarette smoking has little effect on most laboratory tests in a large group of healthy males.
