Pulmonary functional parameters and blood cotinine level in chronic obstructive pulmonary disease.

Conclusions: We observed once again with our study that cotinine is a reliable marker of tobacco exposure. The most obvious result is the negative correlation between FEF25-75% value and cotinine level and this result may be caused by the effect of smoking in the peripheral airways at early stages of COPD.
