Tricyclic antidepressant sample stability and the vacutainer effect.
The authors studied the effects of different sample handling techniques on 17 tricyclic plasma samples. They found that the samples were stable at room temperature for up to 3 days when kept in a glass tube sealed with Parafilm, but the samples were not stable when stored in a Vacutainer tube with the stopper in contact with the plasma.
