3rd Degree Screening offers various types of non-DOT (Department of Transportation) and DOT alcohol testing. Our clinic network includes more than 20,000 locations across the country, including patient service centers, third-party collection sites, and mobile collectors.

There are many types of alcohol tests:


A breath alcohol test measures the amount of alcohol in the air you exhale to determine how much alcohol is in your blood.


Corroborative blood alcohol testing (such as a liver function test (LFT) or a carbohydrate deficient transferrin (CDT) test) provides additional support to a diagnosis of excessive alcohol use.

When used alongside hair alcohol marker testing, a fuller picture relating to evidence of chronic excessive alcohol use can be provided. No single biological marker can currently be relied upon in isolation of other tests to determine a chronic alcohol problem, so blood tests are strongly recommended to be used in conjunction with a hair alcohol marker test.


Our saliva alcohol test is CLIA-waived and DOT-approved on-site, rapid, low-cost alternative to breath or blood testing. Known as the Q.E.D. test, it is easy to administer and provides quantitative results comparable to a blood test. Q.E.D. is ideal for use in corporate programs, criminal justice, drug and alcohol treatment centers, and clinical setting screening programs.


The urine laboratory testing for ethanol (the alcohol found in all alcoholic drinks) indicates if a donor has ingested alcohol within the 24 hours prior to sample collection.


Our hair alcohol marker testing offers combined testing for ethyl glucuronide (EtG) and the fatty acid ethyl ester (FAEE) ethyl palmitate, which are the metabolites of alcohol present in hair after the consumption of alcohol. Using the combination of EtG and FAEE testing provides comprehensive information about chronic excessive alcohol use.

Hair testing for drug(s) of abuse testing can offer up to a 90-day window for detection of drug use prior to the test date. Hair testing requires a small sample of hair that is collected under direct supervision without any invasion of privacy.


Electronic chain of custody

E-Chains reduce costs and administrative duties by eliminating paper forms. Using our paperless system, clinics minimize collection errors, ensure consistency, and link all parts of the applicant-screening process.

Full program management

For a small fee, we offer the option of full program management to take over the time-consuming duties of scheduling and managing your drug and health screening services. When you place an order for a drug or occupational health screen, 3rd Degree Screening works with your employee to find an appropriate clinic and makes sure all the paperwork is ready at the clinic. All forms are provided to the employee and our staff is available to answer all their questions.

Convenient access

Since we have a collection network of over 20,000 national collection sites, we are able to find a site that is convenient for your applicants/employees.
