FAQs
How long is Phosphatidylethanol detectable?
Phosphatidylethanol is detectable in blood for up to 28 days without alcohol.
What can affect Phosphatidylethanol results?
Sex, age, gender and body mass do not influence the normalisation rate of Phosphatidylethanol (PEth). In comparison to serum CDT, PEth appears more sensitive. CDT is an indirect marker, and PEth is a direct marker.
