Cotinine was measured in the serum, saliva, and urine of nonsmokers, passive smokers, and active smokers. Serum and saliva could not discriminate between nonsmokers and passive smokers. Mean urine cotinine was higher in passive smokers than nonsmokers but there was a great deal of intersubject overlap. Cotinine in all body fluids could separate active smokers from the other two groups. Among smokers, light smokers had lower levels than heavier smokers.
对不吸烟者、被动吸烟者和主动吸烟者的血清、唾液和尿液中的可替宁进行了测量。血清和唾液无法区分不吸烟者和被动吸烟者。被动吸烟者尿液中可替宁的平均含量高于不吸烟者,但个体之间存在大量重叠。所有体液中的可替宁都能将主动吸烟者与其他两组区分开来。在吸烟者中,轻度吸烟者的可替宁水平低于重度吸烟者。
