Understanding PEth & ETG Detection
Phosphatidylethanol (PEth) and Ethyl Glucuronide (ETG) are direct biomarkers formed after alcohol consumption. PEth measures blood alcohol exposure over 2–4 weeks, while ETG detects alcohol in urine up to 5 days. This combined calculator helps users track alcohol metabolism, understand detection windows, and plan sobriety monitoring.
Factors Affecting PEth & ETG Detection
- Alcohol consumed (number of drinks, volume, and timing)
- Body weight and gender
- Metabolic rate and liver function
- Hydration and drinking frequency
- Test sensitivity/cutoff levels
Typical PEth & ETG Cutoff Levels
- ETG: 100 ng/mL (high), 200 ng/mL (moderate), 500 ng/mL (standard)
- PEth: 20 ng/mL (high), 50 ng/mL (moderate), 80 ng/mL (low)
How to Use the PEth & ETG Calculator
- Enter weekly drinks and body weight.
- Select ETG and PEth test sensitivity.
