Comparison of analyte concentrations across multiple pre-analytical conditions was conducted, specifically focusing on the ethanolamides and structurally isomeric HETEs. The results indicated that the ethanolamides were similarly influenced by pre-analytical conditions across the whole group; however, the HETE analytes displayed much more diverse changes.
