Detection of Nicotine and Nicotine Metabolites in Units of Banked Blood

Abstract

Abstract Objectives To determine the concentrations of nicotine and nicotine metabolites in RBC units as a means to estimate the point prevalence of exposure within the healthy donor pool. Methods Segments from 105 RBC units were tested for the presence of nicotine, cotinine, or trans-3ʹ-hydroxycotinine by liquid chromatography–tandem mass spectrometry. Results Of the 20 (19%) units that contained detectable concentrations of nicotine, cotinine, or trans-3ʹ-hydroxycotinine, 19 (18.1%) contained concentrations consistent with the use of a nicotine-containing product within 48 hours of specimen collection. One RBC unit contained nicotine concentrations consistent with passive exposure. Conclusions Chemicals from nicotine-containing products are detectable within the US RBC supply. Further investigation is needed to determine the risks of transfusion-associated exposure to nicotine and other tobacco-associated chemicals among vulnerable patient populations such as neonates.
