EtG/EtS Urine Alcohol Testing in San Antonio, TX

Fast, Certified 80-Hour Alcohol Testing on the Northwest Side

At Fastest Labs NW San Antonio, we provide professional EtG/EtS urine alcohol testing for individuals, employers, and legal professionals throughout San Antonio and Bexar County. EtS (ethyl sulfate) is a direct metabolite of alcohol that laboratories measure alongside EtG (ethyl glucuronide) in the same urine specimen, extending the detection window well beyond what a standard breathalyzer can achieve. Our facility delivers confidential, certified results, and our staff handles every collection with proper chain-of-custody procedures so your documentation can hold up with employers, courts, and probation programs alike.

What EtG/EtS Urine Testing Detects & Who It Serves

EtG/EtS urine alcohol testing detects alcohol use for up to 80 hours after consumption. Unlike a breathalyzer, it doesn’t measure current impairment. Instead, it confirms that alcohol entered the body within the detection window, which is why zero-tolerance programs and court systems in Texas rely on it. EtS urine testing is the standard for situations where documented proof of prior consumption matters, including abstinence monitoring, probation compliance, and custody or parole requirements. EtG testing is also available through saliva or EtG hair samples when a shorter or longer detection window better fits your needs.

Our testing services support a wide range of needs in San Antonio, including:

• Employment compliance for companies with drug- and alcohol-free workplace policies
• Legal and court-ordered testing with certified documentation
• Abstinence monitoring and probation compliance for court, parole, and custody requirements
• Personal or family testing for peace of mind

FAQs

How Long After Drinking Can EtG Testing Detect Alcohol in Urine?

EtG urine testing can detect alcohol use for up to about 80 hours, or roughly three to four days, after consumption. Exact timing varies based on personal factors like metabolism and the amount consumed.

Who Might Need an EtG Urine Test in San Antonio?

People seek EtG testing for many reasons: employer screening, court or probation requirements, abstinence monitoring programs, custody arrangements, or personal monitoring. Any situation that requires documented confirmation of alcohol use within the past several days is a candidate for EtG/EtS urine testing.

What Is EtS Testing, & Is It Different from EtG Testing?

EtS (ethyl sulfate) is a direct metabolite of alcohol, similar to EtG. Laboratories measure both metabolites in the same urine specimen, so when providers refer to EtS urine testing or EtG/EtS testing, they’re describing a single combined test. Testing for both can improve accuracy and is the standard approach for certified urine alcohol testing.

Will the Test Show False Positives from Mouthwash or Hand Sanitizer?

EtG/EtS testing targets only metabolites of consumed alcohol. Using typical personal care products as directed won’t normally trigger a positive result, though heavy or prolonged exposure to alcohol-containing products can sometimes affect outcomes.

How Quickly Will I Get My EtG Test Results?

Verified results are typically ready within 1 to 3 business days. We work to return results as quickly as possible without compromising accuracy.

Is My Personal Information Protected?

Yes. Our procedures safeguard your privacy and keep your information secure throughout testing and reporting. Results are shared only with authorized individuals.
