Alcohol consumption marker

Phosphatidylethanol (PEth)

PEth (phosphatidylethanol) is a metabolite of alcohol in the form of a membrane-bound phospholipid, which acts as a direct and specific marker of alcohol intake during the last days and weeks.

What is PEth (phosphatidylethanol)?

PEth is only formed in the presence of ethanol and can be used as a marker of alcohol intake in clinical tests. The PEth concentration gives indications of the extent of alcohol intake.

A single occasion of intoxication does not produce measurable levels of PEth. The half-life is about 4 days. Depending on the starting value, PEth can be detected up to 4 weeks after the end of alcohol intake.

Reference range - high and low PEth value

  • <0.05 µmol/L indicates no or only sporadic alcohol consumption.
  • Values of 0.05-0.30 µmol/L indicate moderate alcohol intake.
  • <0.30 µmol/L indicates extensive and/or regular alcohol intake.

PEth half-life

The half-life of PEth, which is the time it takes for half of an initial amount of PEth to be broken down in the body, is about 4 days. This means that if a person has drunk alcohol and formed PEth, half the amount of PEth will have been broken down after 4 days, and after another 4 days another half will have been broken down.

Knowing the half-life of PEth is important when interpreting PEth results, as it can affect how long a person's alcohol consumption can be detected using PEth.

Information

Medical comment included

With us, you will always receive a doctor’s opinion from a licensed physician when you order a medical check-up that includes a medical opinion. The doctor’s opinion includes an overall assessment of your results from laboratory analysis. The opinion is individual and may vary depending on the specific tests your medical check-up includes.

What can I expect in the medical report?

The medical opinion will summarize the results of your test results to give you an assessment of your health including any abnormalities outside the reference ranges. In case of abnormalities or need, your doctor may also contact you for a free conversation to explain and talk about your results. Remember that a health check always includes specific test results based on your health and your personal circumstances. Values outside the reference range should therefore always be discussed with a doctor before any decisions regarding possible treatment are made.

What does the doctor look at during a health check?

When assessing a blood test or health check, your doctor will look at several different parameters to evaluate your health and identify any abnormalities. Below are some common aspects your doctor may examine:

Blood counts: Your doctor will check red, white and platelet counts to identify any signs of anaemia, infection or bleeding.

Nutrients and biochemical markers: Includes, for example, analysis and monitoring of blood sugar (glucose) levels, electrolyte levels (e.g. sodium, potassium), liver function tests (e.g. liver enzymes), kidney function tests (e.g. creatinine, urea) and lipid profile (e.g. cholesterol, triglycerides). The results of the tests give your doctor a better idea of your organ function, blood sugar level, cholesterol conditions and other important health aspects.

Inflammatory markers: Your doctor may measure health markers such as C-reactive protein (CRP) or red blood cell decrease rate (SR) to evaluate inflammatory conditions or confirm an active infection.

Hormone levels: Your doctor may monitor your hormone levels to assess hormonal imbalances or diseases, such as thyroid hormones (TSH, T3, T4), sex hormones or other specific hormones such as testosterone levels.

Specific tests: Depending on your goal of your health check or medical history, your doctor may look into specific tests to investigate conditions or diseases, such as diabetes, vitamin deficiency or autoimmune diseases.

In conclusion, the doctor weighs all test results based on the health check to assess your overall health, detect any abnormalities and identify possible underlying medical conditions.

What happens if I have abnormal test results?

If your blood count is abnormal, this will be addressed in your personal medical opinion. Depending on the nature and extent of the abnormality, your doctor may also contact you directly through the test result service for further guidance. Various measures and advice will be provided based on the specific abnormalities observed along with your medical history.
