Phosphatidylethanol (PEth)

Phosphatidylethanol in Blood (PEth) is used for detecting chronic excessive drinking behaviour with a regular daily alcohol intake.

Phosphatidylethanol in Blood (PEth) is a stable, highly specific and sensitive marker for detecting chronic excessive drinking behaviour with a regular daily alcohol intake.

  • PEth is found to be detectable in blood up to 28 days without alcohol.
  • Sex, age, gender and body mass do not influence the normalisation rate of PEth.
  • In comparison to serum CDT, PEth appears more sensitive.
  • CDT is an indirect marker, PEth is a DIRECT marker.
  • 99% clinical specificity when differentiating between abstainer and non-abstainer.
