FAQ: PEth Testing for Alcohol Use
What is PEth (Phosphatidylethanol)?
PEth (Phosphatidylethanol) is a very specific alcohol biomarker and provides the highest sensitivity for the detection of current, regular alcohol consumption. It is particularly effective for detecting chronic and heavy drinking where it is critical in settings such as the monitoring of individuals with known alcohol use issues, child protection cases and drink driving violations.
What are the advantages of PEth testing?
Phosphatidylethanol (PEth) only forms in the presence of Ethanol, meaning it is a direct marker for alcohol intake. This makes it a more sensitive indicator than existing blood markers of CDT, LFT and FBC.
Is a PEth test better than a hair alcohol (EtG) test?
PEth is eliminated from the body in about 30 days, meaning the window of detection is often given as one month.
Collection of both a hair and blood sample can complement each other to show comparisons or differences between recent and long-term alcohol use.
What sample is used for PEth testing?
A sample of blood is collected via a finger prick using a compact device supplied by Cansford Laboratories. The collected sample is converted to a dried blood spot – a convenient technique for collection, transport, and storage.
A number of blood drops need to be collected in the specially designed collection kit.
Is DBS PEth quantitative? Yes!
PEth 16:0/18:1 <20 ng/mL:
Abstinence or irregular low alcohol consumption in the approximate month prior to the sample collection.
PEth 16:0/18:1 between 20 – 200 ng/mL:
Consistent with alcohol consumption, but not at an excessive level, in the approximate month prior to the sample collection.
PEth 16:0/18:1 >200 ng/mL:
Excessive alcohol consumption in the approximate month prior to the sample collection.
