What Is an ETG Test?

An ethyl glucuronide (ETG) alcohol test is a laboratory test that detects the presence of ETG in your urine or through a hair sample. ETG is a metabolite of alcohol, or a byproduct of the process your body uses to metabolize alcohol after you ingest it. The test is used to monitor alcohol abstinence in people who are in treatment programs or under court supervision, or to detect or investigate alcohol consumption for people who are suspected of DWI. A urine test can be conducted up to 80 hours after consumption, and a hair test can be conducted up to 90 days after consumption.

How an ETG Alcohol Blood Level Calculator Works

An ETG calculator is a device or program that estimates how long it will take for your body to be rid of the metabolites present after consuming alcohol. The accuracy of the calculator depends upon the accuracy of the information provided, including:

  • Weight
  • Age
  • Gender
  • Amount of alcohol consumed
  • Time since last drink

The program then uses formulas that are based on average physiological data. The goal is to provide you with a prediction or estimate as to when your body’s ETG levels will be below detectable thresholds. It is very important to be aware of the fact that this calculator provides an estimate, not a guarantee. Individual factors like your physiology and biology, age, food consumption, and lifestyle can play a huge role in how accurate the results are. The best way to protect yourself from a DWI charge is to not drink and drive.

Understanding Your Blood Alcohol Content (BAC) Level

Blood alcohol content (BAC) is a measurement of the amount of alcohol in your bloodstream. It is indicated as a percentage that conveys the level of impairment and potential danger associated with alcohol consumption. The legal limit for driving in New York is a BAC of 0.08%; however, lower BACs can still cause impairment of driving ability, vision, judgment, reaction time, and coordination. Your BAC is influenced by your weight, gender, biology and physiology, age, food intake, and speed of drinking. BAC is measured using a breathalyzer or a blood sample.

How a Blood Alcohol Calculator Works

An alcohol blood content calculator is a tool that provides an estimate of your blood alcohol content. It uses formulas and self-reported data to determine what your BAC might be based on standards; however, it is not an exact measurement. Some factors that influence the accuracy of a BAC calculator include your individual biology, body fat percentage, metabolism, weight, age, and health. While a BAC calculator can give you a rough estimate, it should not be relied upon as a tool to determine if it is safe to drive. You can still be charged with DWI if you drive with a BAC over 0.08%, even if a BAC calculator told you that your BAC was lower.

FAQs About ETG and BAC Calculators

A laboratory ETG test is influenced by your liver function, hydration, genetics, and other factors that cannot be accounted for by a simplified online calculator. It is not precise enough for legal or medical use as it uses average rates, user-reported data, and assumptions.

BAC is typically calculated using the Widmark formula, wherein your BAC is equal to (grams of alcohol/ (body weight in grams * r)) * 100; with r being a gender-specific constant of 0.68 for men and 0.55 for women, and grams of alcohol consumed is calculated by multiplying the number of standard drinks consumed by 14 grams.

Your liver metabolizes alcohol and converts a small amount of it into ethyl glucuronide (ETG) during the metabolization process. The peak ETG level in urine is roughly correlated to the BAC level in your blood or as calculated by a breathalyzer test. ETG is eliminated from your body at about 100-200 ng/mL every hour after the level peaks.

You will need to input accurate data regarding the number of standard drinks you have consumed, your body weight, your gender, and the time that has elapsed (in hours) since your last drink.
