ETG Test Strips – 80 Hour Alcohol Detection
Test for alcohol in record time with these ETG Urine Test Strips. Accurate and easy to use, these test strips detect ethyl glucuronide (ETG) a direct metabolite of ethanol for up to 80 hours after alcohol consumption. Buy in bulk and stock your practice with high-quality, fast-acting drug tests today.
What is ETG and How Does It Work
Ethyl-glucuronide or ETG is a metabolite formed in the body through glucuronidation once a person has been exposed to ethanol usually in the form of drinking alcohol. When someone consumes alcohol even in relatively small amounts the liver converts ethanol into ETG via enzymatic processes.
Unlike ethanol which is eliminated within hours ETG remains detectable in urine for extended periods making it a superior biomarker for monitoring alcohol abstinence. As such a urine test can be administered to detect the substance within the body. For rapid results test strips such as these are the easiest way to collect samples and get results within minutes. ETG is water-soluble stable and non-volatile characteristics that make it highly effective for routine alcohol consumption testing compared to traditional blood or breath alcohol tests.
ETG Detection Windows by Cut-off Level
Research from the National Institute on Alcohol Abuse and Alcoholism (NIAAA) and published in peer-reviewed journals demonstrates that ETG detection varies significantly by cut-off level and drinking pattern. Our ETG test strips are available in two clinical configurations to meet different testing needs.
300 ng/ml Cut-off
The 300 ng/ml cut-off level provides enhanced sensitivity for detecting light to moderate drinking. At this threshold ETG can be detected for up to 80 hours or 3.3 days after heavy alcohol consumption and approximately 24 to 48 hours after light drinking. This cut-off is ideal for treatment programs requiring maximum detection capability and monitoring abstinence in recovery settings.
500 ng/ml Cut-off
The 500 ng/ml cut-off level is the SAMHSA-recommended standard for forensic applications. Clinical studies show that 500 ng/ml detects heavy drinking from the previous day with 78% accuracy and maintains detection for 24 to 72 hours depending on alcohol quantity consumed. This higher threshold minimizes false positives from incidental alcohol exposure while maintaining reliability for recent heavy drinking detection.
100 ng/ml vs 500 ng/ml Comparison
Studies published in PMC demonstrate that 100 ng/ml cut-offs detect 79% of heavy drinking over five days but carry higher false positive rates from environmental exposure. Conversely 500 ng/ml cut-offs reduce false positives to approximately 3% but may miss light drinking beyond 24 hours. Selecting the appropriate cut-off depends on your specific clinical or forensic requirements.
False Positive Prevention and Interference
While ETG test strips are highly specific, certain environmental and product exposures can cause false positive results, particularly at lower cut-off levels. Understanding these sources is essential for accurate result interpretation.
Common Sources of False Positives
Personal Care Products
- Hand sanitizers (60%+ ethanol)
- Mouthwashes (e.g., Listerine)
- Cosmetics (aftershave, hair dye)
- Antiperspirants
Medications & Food
- Cough syrups and elixirs
- Foods (liqueur desserts, wine sauces)
- Fermented products
Household Products
- Cleaning products containing ethanol
Prevention Recommendations
To minimize false positives, donors should avoid alcohol-containing products for 24 hours before testing. For forensic applications, the 500 ng/ml cut-off is recommended to eliminate incidental exposure results.
Reliable Sobriety Testing with Advanced ETG Strips
Our ETG strips are engineered for individuals and organizations that require a “zero-tolerance” monitoring solution. Unlike standard alcohol tests that only detect ethanol for a few hours, these strips identify the presence of Ethyl Glucuronide (EtG), a biomarker that remains in the urine for up to 3.3 days after consumption. This makes ETG strips the gold standard for verifying long-term sobriety and compliance.

How to use Drug Test Strip
FORENSIC USE PRODUCT
This is a Forensic Use Only device and is intended for use only in drugs of abuse testing for law enforcement purposes.
Appropriate users of such devices include, for example, court systems, police departments, probation/parole offices, juvenile detention centers, prisons, jails, correction centers, and other similar law enforcement entities, or laboratories or other establishments performing forensic testing for these entities.
Some drug test kits that test for Fentanyl, and specialty tests, like the K2/Spice, Alcohol (ALC), Cotinine (COT), Ethyl-Glucuronide(ETG), Fentanyl(FEN), Synthetic Marijuana (K2), Ketamine (KET), Lysergic Acid Diethylamide (LSD), Methaqualone (MQL), Bath Salts (MDPV), Kratom (Krat), Tianeptine (ZAZA), Xylazine Psilocybin(Mushrooms) drug test, fall under the category of Forensic Use Only.
These designations are clearly marked on the product’s page. Some saliva/oral-based drug detection devices are for forensic use only. However, if you have any doubts about the intended use and setting for any rapid screening device, it’s advisable to contact claire@buytestcup.com.
Frequently Asked Questions
How do ETG strips differ from a breathalyzer?
A breathalyzer only detects alcohol currently in your breath (usually within 12-24 hours). ETG strips detect the metabolite left behind after the alcohol has been processed by your liver, allowing for a detection window of up to 80 hours.
What is the most common cut-off for ETG strips?
The 500 ng/mL cut-off is the industry standard for forensic and clinical use. It is high enough to avoid false positives from incidental exposure (like fermented foods) but sensitive enough to catch recent drinking.
Are these strips suitable for court-ordered testing?
These strips provide a “Preliminary Analytical Result.” For legal or court cases, a positive result should always be confirmed by a certified laboratory using LC/MS or GC/MS methods.
What is the difference between 300 ng/ml and 500 ng/ml cut-offs?
The 300 ng/ml cut-off provides enhanced sensitivity detecting lighter alcohol use for longer periods but may have slightly higher false positive rates from environmental exposure. The 500 ng/ml cut-off is the forensic standard minimizing false positives while reliably detecting recent heavy drinking.
Can ETG tests detect one beer?
Yes ETG tests can detect even small amounts of alcohol consumption including one standard drink. Detection depends on timing cut-off level and individual metabolism. At 300 ng/ml sensitivity single drink detection is possible for 24 to 48 hours.
Do ETG test strips show current intoxication?
No ETG test strips detect historical alcohol use not current impairment. ETG remains in the body long after alcohol is metabolized and intoxication effects have ended. For current impairment breathalyzers or blood alcohol tests are required.
