Cigarette smoking histories were compared to carboxyhemoglobin and serum thiocyanate concentrations obtained from 426 smokers and 191 non-smokers. The mean levels of both carboxyhemoglobin and serum thiocyanate wefe significantly higher among cigarette smokers and correlated with number of cigarettes smoked per day. The specificity of both procedures was 81 per cent, and serum thiocyanate had a higher sensitivity (93 per cent vs. 83 per cent), making it potentially more suitable for use as an index of cigarette smoking.
将426名吸烟者和191名非吸烟者的吸烟史与测得的碳氧血红蛋白及血清硫氰酸盐浓度进行了比较。吸烟者的碳氧血红蛋白和血清硫氰酸盐平均水平均显著较高,且与每日吸烟量相关。两种检测方法的特异性均为81%,血清硫氰酸盐具有更高的灵敏度(93%对83%),使其可能更适合用作吸烟指标。
