1. Study Purpose

   The purpose of this study was to determine the effects of storing blood in Starstedt Monovette tubes on the quantification of ethylbenzene and xylene. Expired volatile-free hemolyzed blood-bank whole blood was used for all assays.

   Summary of Findings:

   Storage of blood at room temperature for 96 h in Monovette tubes resulted in measureable levels of o-xylene, ethylbenzene, and m-xylene. The magnitude of the increase was dependent on the age of the tubes with tubes furthest from expiration having the largest effect. The authors report that Starstedt Monovette serum gel tubes, and Becton Dickinson Vacutainer STT gel and clot activator tubes do not cause an increase in the concentration of volatiles.
