PEth Blood Test
Highly accurate analysis detecting Phosphatidylethanol (PEth), a direct biomarker of alcohol consumption over 3-4 weeks.
PEth Blood Test
Phosphatidylethanol (PEth) is a particular alcohol biomarker and provides the highest sensitivity for the detection of current regular alcohol intake. PEth testing is particularly effective for detecting constant and heavy drinking where it is critical in settings such as the monitoring of doctors, child custody or drink driving violations.
At Noble Med Solutions, only a few drops of blood in the form of ‘dry blood spots’ that are taken for analysis at a laboratory is required. Known as PEth testing, it offers a modern, sensitive alternative to traditional methods of blood testing for alcohol.
PEth enables the discrimination of heavy versus moderate or occasional drinkers, and can monitor abstinence within the past month. Age, gender, health or previous alcohol issues do not impact on the results.
What is PEth?
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 markers of CDT, LFT and FBC. PEth can be detected for up to a month.
Collection Method
Via a finger prick using a compact device, a convenient technique for collection, transport, and storage. A number of blood drops need to be collected in a specially designed collection kit.
Advantages:
- PEth is more accurate, much easier to collect, and not costlier than the traditional blood tests.
Disadvantages:
- Alcohol testing a PEth blood sample provides a view of the last month of consumption. If for a longer period, a hair alcohol test can cover up to six months of consumption.
