What Is EtG Alcohol Testing?
EtG testing detects ethyl glucuronide, a direct metabolite of alcohol that remains in the system much longer than alcohol itself. This advanced testing method provides:
- Detection of alcohol consumption up to 80 hours (3-4 days) after use
- A much longer detection window than breath tests (which only detect recent use)
- The ability to identify even relatively small amounts of alcohol consumption
- A more comprehensive alcohol monitoring solution
Standard EtG Urine Test
Our basic EtG urine test provides an 80-hour detection window for alcohol consumption. The test identifies the presence of the ethyl glucuronide metabolite at various cutoff levels.
EtG Legal Compliance Testing
For court-ordered monitoring, this test includes proper chain-of-custody documentation and result certification to ensure legal defensibility.
EtG with Drug Panel Combination
This comprehensive option pairs EtG alcohol testing with standard drug panels for complete substance screening in a single test.
Workplace EtG Testing
Extended alcohol screening for safety-sensitive positions requiring longer detection windows than standard breath testing provides.
Who Requires EtG Testing
Our EtG alcohol testing serves multiple purposes:
- Legal monitoring for courts, probation, and custody arrangements
- Workplace testing for safety-sensitive positions requiring alcohol abstinence
- Compliance verification for various monitoring programs
- Personal verification of alcohol abstinence
EtG Testing Technology
Our EtG testing utilizes advanced laboratory methods:
- Initial screening using enzyme immunoassay (EIA) technology
- Confirmation of positive screens using LC-MS/MS technology
- Multiple cutoff level options (100 ng/mL, 250 ng/mL, 500 ng/mL)
- Analysis performed at certified reference laboratories
Understanding EtG Testing Detection Windows
EtG testing offers significant advantages for alcohol monitoring:
- Traditional breath tests only detect alcohol for 12-24 hours
- Blood testing detection is limited to approximately 12 hours
- EtG urine testing extends detection window up to 80 hours
- Sensitivity allows detection of even small amounts of alcohol consumption
Test Smartly Labs offers this advanced testing at all five of our Kansas City locations. Our EtG alcohol testing provides a powerful tool for extended alcohol detection when longer monitoring periods are required.

Frequently Asked Questions
- Can EtG testing distinguish between alcoholic beverages and other alcohol sources?
EtG testing cannot definitively distinguish between different sources of alcohol. The test detects ethyl glucuronide, a metabolite formed when the body processes ethanol (alcohol) from any source. This means exposure to alcohol-containing products like certain foods (particularly fermented items), mouthwash, hand sanitizers, and some medications could potentially trigger positive results, especially at very low cutoff levels. This is why different cutoff thresholds are used depending on testing purposes -- higher cutoffs (500+ ng/mL) generally indicate beverage consumption while minimizing the chance of environmental exposure positives.
- What factors affect how long EtG remains detectable?
Several factors influence EtG detection times: amount of alcohol consumed (higher consumption typically leads to longer detection); individual metabolism and body composition; hydration levels (diluted urine can affect concentration); liver function (which processes alcohol); gender (women may metabolize alcohol differently than men); medication use; and general health factors. While the 80-hour window is a general guideline, actual detection times vary significantly between individuals. Heavy drinking may be detectable beyond 80 hours, while minimal consumption might clear the system more quickly.
- What's the difference between different EtG cutoff levels?
EtG tests are available with different cutoff thresholds: 100 ng/mL, 250 ng/mL, and 500 ng/mL are common. Lower cutoffs (100 ng/mL) provide maximum sensitivity but may detect incidental alcohol exposure from sources other than beverages. The 500 ng/mL cutoff is less likely to trigger positives from environmental exposure but still detects significant alcohol consumption. For legal monitoring, courts often specify which cutoff level to use. Test Smartly Labs can advise on appropriate cutoff levels based on your specific testing needs.
- Is EtG testing admissible in court?
Yes, EtG testing is widely accepted in legal proceedings when performed with proper chain-of-custody documentation. Courts regularly use EtG testing for monitoring alcohol abstinence in cases involving DUI/DWI probation, child custody arrangements, and other situations requiring alcohol monitoring. Test Smartly Labs follows strict protocols to ensure legal defensibility, including proper specimen collection, chain-of-custody documentation, testing at certified laboratories, and appropriate result certification. Always bring any court documentation regarding specific testing requirements to ensure we meet all mandated procedures.
- How does EtG testing compare to other alcohol testing methods?
Each alcohol testing method serves different purposes. Breath and blood testing measure current alcohol concentration (intoxication level) but have very short detection windows (hours). Hair testing can detect long-term patterns of heavy use over months but doesn't effectively identify recent or occasional use. EtG testing fills the middle ground -- it can't measure current intoxication levels but provides a much longer detection window (days instead of hours) compared to breath or blood testing. This makes EtG ideal for abstinence monitoring when you need to know if someone has consumed alcohol in the past few days rather than if they are currently intoxicated.

A lab-based ETG / ETS Urine Alcohol Test: The ethyl glucuronide (EtG) test is widely used to detect the presence of ethyl glucuronide, which is a metabolite of ethanol, the intoxicating agent in alcohol. EtS (ethyl sulfate) is another metabolite of ethanol. EtG can detect the usage of alcohol between 48-72 hours in most cases. Specimen Type: Urine

This Hair Follicle Alcohol Test is used to detect alcohol usage with a detection window of up to 90-days since ingestion. EtG alcohol tests are widely accepted and used to detect the presence of ethyl glucuronide (EtG), which is a direct metabolite of ethanol. Ethanol is the intoxicating chemical in alcohol. EtS (ethyl sulfate) is a secondary metabolite of ethanol and can also be detected by the hair follicle test. EtG in the Hair Follicle can detect the usage of alcohol up to 90 days since usage. This is a lab-based test and analysis. Specimen Type: Hair Follicle

This EtG (ethyl glucuronide) Nail Alcohol test is commonly used to detect the presence of ethyl glucuronide, which is a direct metabolite of ethanol. Ethanol is the intoxicating chemical in alcohol. EtS (ethyl sulfate) is also metabolite of ethanol which is also detectable in human nails. EtG and EtS in human fingernails or toenails can be detected the usage of alcohol up to 6 months which is significantly longer than Urine EtG (72 hours) or Hair Follicle EtG (90 days) testing. Specimen Type: Nails (Fingernails or Toenails)
