An EtG calculator estimates the detection window for Ethyl Glucuronide, a metabolite produced when the body processes alcohol. EtG urine tests are used in substance abuse monitoring, workplace programs, and legal settings to detect recent alcohol consumption for 24 to 80 hours after drinking, even when BAC has returned to zero. The calculator estimates how long EtG may remain detectable based on the amount of alcohol consumed, the time of consumption, and the detection threshold of the specific test used. It is commonly used by individuals on abstinence-based probation or in alcohol treatment programs.
EtG calculators are for educational and informational purposes only and should not be used to attempt to cheat drug tests. Results are estimates based on general population data and individual metabolism varies significantly. Factors such as liver health, hydration, age, and kidney function all affect EtG excretion rates. Courts, employers, and treatment centers set specific EtG cutoff thresholds, typically between 100 and 500 ng per mL. People in recovery or under court supervision should always consult their program coordinator about testing expectations. The EtG test is used specifically because of its ability to detect alcohol use beyond the standard blood alcohol testing window, making it a stricter deterrent.
