How Long Does Alcohol Stay in Your System? – Depending on the body system and test used, alcohol detection times may vary. Alcohol can stay in your system between 6-72 hours in most cases depending on the detection test used. Alcohol detection tests can measure alcohol in the blood for up to 6 hours, on the breath for 12 to 24 hours, urine for 12 to 24 hours (72 or more hours with more advanced detection methods), saliva for 12 to 24 hours, and hair for up to 90 days.
|Body System||Time in System|
|Blood||Up to 6 Hours|
|Urine||12-24 Hours; 72 Hours or more for newer test methods|
|Hair||Up to 90 Days|
Can urine test detect long term alcohol use?
EtG can be detected in the blood for up to 36 hours and in the urine for up to 5 days after heavy alcohol use. In addition to blood and urine, EtG is detectable in other body fluids, hair, and body tissues (Wurst et al.
When do EtG levels peak?
Subjects and assessment – This study reports the retrospective analysis of routinely collected clinical and biochemical data from the Centre for Addiction Medicine, National Institute of Mental Health and Neurosciences, Bangalore. We reviewed the records of 210 participants with a diagnosis of alcohol dependence syndrome (ADS) according to the International Classification of Diseases-10.
- Patients using any substance other than nicotine were excluded from the study.
- Peak serum EtG and EtS levels are expected after 4-5 hours of alcohol consumption.
- Eeping this in mind we excluded patients who had consumed alcohol in the 5 hours preceding recruitment and collection of sample.
- We excluded patients using beer, wine, or country liquor due to two reasons.
First, wine and beer have a high content of polyphenols and flavonoids that affect EtG and EtS metabolism. Second, all hard drinks allowed by government regulations (whiskey, rum, vodka, or gin) have a content of 42.8% alcohol by volume. This allowed us to quantify a standard drink (30 mL) which is equivalent to approximately 14 g of ethanol.
In addition, patients who presented to the clinic under the obligation of law enforcement agencies or employer were also excluded from the study as these factors are known to cause misreporting. After these exclusions, we had a sample of 152 participants. For this study, we focused on data regarding last alcohol consumption.
These data were collected using a calendar method, similar to the alcohol timeline follow back. Self-reported time since last alcohol consumption in hours is recorded as a continuous integer. A number of standard drinks consumed at the most recent drinking episode is also assessed as a continuous integer.
Patients with a diagnosis of ADS attending our outpatient clinic are routinely evaluated for biomarkers of alcohol use including CDT, GGT, serum EtG, and serum EtS. We have used serum EtG and EtS data for this study. Blood samples are collected under aseptic precautions, and separated serum is used for EtG and EtS quantification.
Samples were transported immediately to the laboratory, stored at − 20°C, and analyzed within a week of collection. The Institute Ethics Committee has approved this study involving analysis of routinely collected clinical and biochemical data.
How much EtG is in a drink?
Typically a single drink (or 4oz glass of wine) causes a peek level at about 2-4 hours of somewhere around 400ng/ml of EtG. By 24 hours the level of EtG is usually going to be much lower, at about 100ng/ml.
What should I drink before a urinalysis?
– Before your test, make sure to drink plenty of water so you can give an adequate urine sample. However, drinking excessive amounts of water may cause inaccurate results. One or two extra glasses of fluid, which can include juice or milk if your diet allows, is all you need the day of the test.

Some other drugs can affect your results as well. Tell your doctor about any substances you use before doing a urinalysis.
How long does it take for EtG to leave your system calculator?
One of these byproducts, ethyl glucuronide (EtG), can be detected in urine for up to three days after a person’s last drink.
How far back can EtG test for alcohol?
Alcohol EtG Testing – Urine or Hair – Particular for court ordered alcohol testing, EtG is the popular test for alcohol. Ethyl Glucuronide (EtG) is a direct metabolite of beverage alcohol (ethanol). Its presence in urine may be used to detect recent alcohol consumption, even after ethanol is no longer measurable.
The presence of EtG in urine is a definitive indicator that alcohol was ingested. With urine EtG alcohol testing there is about an 80 hour lookback period, with hair follicle EtG alcohol testing detection is up to 90 days. EtG tests are commonly used for individuals on court ordered probation, child custody proceedings and persons in a substance abuse treatment program.
EtG test results can be sent to the donor or other authorized party such as an attorney, probation officer or the court. The EtG test, properly known as Ethyl Glucuronide is a metabolite produced from drinking alcohol and is used to detect alcohol levels in urine.
It is being used by courts and probation departments as a way of testing if people are drinking. EtG is a reliable indicator of alcohol consumption as the metabolite can be found in urine for up to 80 hours after drinking. EtG testing can be a very effective tool in monitoring individual abstinence when used in conjunction with other monitoring techniques such as increased surveillance, case manager contact and interviews with family members or employers, if appropriate, to determine if relapse has occurred.
EtG alcohol testing is available for court ordered programs, probation, legal cases, divorce, child custody and other alcohol monitoring program. e7 Health works with many attorneys for EtG alcohol testing with urine or with hair. Early recognition of problem drinking or relapse for court-related purposes such as criminal justice or child welfare is important to help assure effective treatment and to protect at-risk populations.
- The EtG test is a urine sample test that detects the presence of ethyl glucuronide when someone has consumed alcohol.
- The urine tests are usually given to people who have been court-ordered not to drink alcohol or by employers who randomly tests employees to determine if they have been drinking on the job.
The EtG test is sensitive to even very low levels of alcohol and can detect alcohol in a person’s system several days after their last drink. The test is so sensitive, however, that it has been known to give positive results when someone has merely come in contact with alcohol through the use of common household products.
