How to Use the Calculator
Follow these simple steps to estimate your PEth levels:
- Average Standard Drinks Per Day: Enter your average number of standard drinks consumed per day. A standard drink typically contains about 14 grams of pure alcohol, equivalent to 12 oz of regular beer, 5 oz of wine, or 1.5 oz of distilled spirits.
- Number of Days Drinking in Last 30 Days: Input the total number of days you consumed alcohol in the past 30 days.
- Drinking Pattern: Select whether your drinking days were consecutive or spaced out. This affects how PEth accumulates and decays in your body.
- Age: Provide your age in years.
- Weight (kg): Enter your body weight in kilograms. (1 kg = 2.20462 lbs)
- Gender: Select your gender as it influences alcohol metabolism rates.
- Click on the “Calculate PEth Level” button to see your estimated PEth level.
The results will display your estimated PEth level in nanograms per milliliter (ng/mL), along with an interpretation of what this level indicates regarding your alcohol consumption.

Frequently Asked Questions (FAQ)
What is PEth?
Phosphatidylethanol (PEth) is a direct biomarker formed in the body only in the presence of ethanol (alcohol). It accumulates in red blood cell membranes and can be detected for up to 2-4 weeks after alcohol consumption, making it a reliable indicator of recent alcohol intake.
How accurate is the PEth Alcohol Calculator?
The calculator provides an estimation based on general models of PEth accumulation and elimination. Individual variations in metabolism, health conditions, and other factors can affect actual PEth levels. For precise measurements, laboratory testing is recommended.
Can PEth levels be influenced by factors other than alcohol?
PEth is only formed in the presence of ethanol, so it’s highly specific to alcohol consumption. However, factors like liver function, metabolic rate, and red blood cell lifespan can influence PEth levels.
How long does it take for PEth levels to return to zero after abstaining?
PEth has an average half-life of approximately 4 days. It may take about 2-4 weeks for PEth levels to become undetectable after stopping alcohol consumption, depending on initial levels and individual factors.
Is this calculator suitable for medical or legal purposes?
No, this calculator is intended for educational and informational purposes only. It should not be used as a substitute for professional medical advice or for legal determinations. Always consult a healthcare professional for concerns about alcohol use.
