LC-MS sample prep for consistent phosphatidylethanol (PEth) analysis in whole blood

Phosphatidylethanol (PEth) is an atypical phospholipid that can be found in the cell membrane of red blood cells. Up to 50 different PEth homologues occur naturally. Each has different abundancies and half-life times. Explore the advantages of using PEth as a biomarker for alcohol intake, and learn more about Tecan’s LC-MS/MS solutions for the measurement of PEth in whole blood.
