Alcohol Detection Periods
Breath Alcohol Current / Immediate | ETG - Urine 80 Hours | Standard Urine 1 - 2 Days |
Whether you want to detect current alcohol impairment, recent alcohol consumption, or alcohol usage within the past 3 days, Accredited Drug Testing offers the testing services that fit your needs.
Alcohol tests are administered for a variety of different reasons and greatly differ from drug tests. Drug tests (those that analyze samples of hair and urine) attempt to detect usage of illegal drugs over a lengthy time period, generally ranging from a week to several months. However, alcohol tests are aimed at detecting consumption of a legal - though regulated - substance within a much shorter timeframe. Rather than testing for past usage, an alcohol drug test will register only the immediate presence of alcohol in the human body.
Breath Alcohol Drug Test
Otherwise known as a breathalyzer, Breath Alcohol Test (BATs) make frequent appearances in sitcoms and crime shows. That is because they are quite commonly used given that the test is easy to administer and provides nearly instantaneous results. Police officers rely on breathalyzer exams to detect when drivers are on the road and above the legal alcohol limit. Because BATs provide only a current-moment snapshot of the body's blood alcohol content, they should only be administered when someone is required to be sober at the current time. Such cases would include driving a vehicle or operating heavy machinery.
Accredited Drug Testing centers are dedicated to providing accurate results every time. For that reason, our certified staff only administers DOT-approved Evidential Breath Testing devices (EBTs). Procedures are meticulously controlled to ensure that all results are admissible in a court of law.
DOT only permits a breath alcohol test. Urine alcohol tests are not permitted by the Department of Transportation. Therefore, a DOT regulated employee would take a 5 panel DOT urine test but only a breath alcohol test if required.
Urine Alcohol Drug Test Finally, for rare cases an EtG exam will be administered to determine if alcohol has been consumed over a 5 day period. EtGs are typically reserved for individuals undergoing a court-ordered sobriety or alcohol rehabilitation program.
Saliva / Oral Fluid Alcohol Test
Accredited Drug Testing also offers a saliva specimen alcohol test in addition, to breath and urine testing. Oral fluid alcohol test can provide immediate results or if requested can be sent to certified laboratory for analysis
Confidential alcohol drug tests can be conducted at any location utilizing the Accredited Drug Testing mobile on-site program service.

AI Overview
Alcohol Testing
Alcohol testing is a procedure used to measure an individual's blood alcohol content (BAC) or detect the presence of alcohol in the body. This testing is crucial in various contexts, including law enforcement, workplace safety, and medical screening. For consumers, understanding the available methods and their specific uses can help in making informed decisions about alcohol testing.
Methods of Alcohol Testing
- Breathalyzer Tests: These are the most common form of alcohol testing, especially used by law enforcement. They measure the alcohol content in the breath, which correlates with blood alcohol levels.
- Blood Tests: Considered the most accurate method, blood tests directly measure the alcohol concentration in the bloodstream. However, they require professional medical personnel to collect the blood sample.
- Urine Tests: Urine tests are less commonly used for alcohol because of their less accurate representation of current blood alcohol levels but can detect alcohol consumption up to 24 hours after intake.
- Saliva Tests: These tests are less invasive and can detect the presence of alcohol in the saliva, which is a good approximation of BAC.
Applications of Alcohol Testing
Alcohol testing is used in several key areas:
- Law Enforcement: To enforce drinking and driving laws and ensure public safety.
- Workplace Safety: In industries where operating heavy machinery or driving is involved, employers use alcohol testing to ensure a safe work environment.
- Health Monitoring: Medical professionals may require alcohol testing for patients undergoing treatment for alcohol use disorder or monitoring those with specific health conditions.
Advantages of Alcohol Testing
Alcohol testing offers several benefits:
- Prevention of Accidents: It helps in reducing the risk of accidents associated with alcohol consumption, especially in driving and workplace scenarios.
- Health and Safety Compliance: It ensures compliance with health and safety regulations, particularly in work environments.
- Support for Recovery Programs: Regular testing can support individuals in recovery programs by holding them accountable and encouraging sobriety.
Limitations of Alcohol Testing
Despite its benefits, alcohol testing has limitations:
- Variability in Accuracy: Some methods, like breathalyzers, can sometimes give false positives due to factors like diet, medical conditions, or even certain medications.
- Invasiveness: Some methods, particularly blood tests, are invasive and require professional handling.
- Privacy Concerns: The necessity to disclose personal consumption habits can raise privacy issues, especially in employment contexts.
In conclusion, alcohol testing plays a critical role in law enforcement, workplace safety, and health care. While it offers numerous benefits in promoting safety and health standards, awareness of its limitations and appropriate use is essential for achieving accurate and reliable results.

Local Area Info: Oak Forest, Illinois
Human habitation in Oak Forest began during the early Holocene. This is made evident by the remains of hunting camps on what would become the grounds of the city's hospital. Several millennia later, the final known indigenous settlement in Oak Forest, a Potawatomi longhouse village, was established nearby. However, it was abandoned by the 1620s.
The origins of present-day Oak Forest begins with a railroad whistle stop on the Chicago, Rock Island and Pacific Railroad 1 block south of the intersection of 167th street and Central Avenue which primarily served area dairy farmers. This stop was located in a largely forested area of what was previously known as the Cooper's Grove Stand of Timber. By the 1880s this particular area of timber was being referred to as the "Oak Forest" due to its abundance of oak trees. A section of the former "Cooper's Grove Road" paralleling the railroad track from 66th Court to 167th Street in Tinley Park became known as "Oak Forest Avenue," because it was the road from the Village of Bremen/New Bremen (now Tinley Park) that lead to this "Oak Forest."
In 1907, Cook County approved construction of a second county poor farm and infirmary on a site generally at the southeast corner of 159th Street and Cicero Avenue to address overcrowding conditions at the County Poor Farm in Dunning on the northwest side of Chicago. This location was very near the Rock Island railroad and a new railroad station was constructed northwest of the present day intersection of 159th Street (US Route 6) and Cicero Avenue (Illinois Route 50), which provided convenient rail access to the facility. A railroad spur off of the Rock Island railroad line was also constructed onto the Oak Forest Hospital site that was used for both delivery of materials during its construction and delivery of coal for its heating plant and other goods used at the facility for many years. The Oak Forest Infirmary opened in 1910. Shortly after its opening, the facility accommodated close to 2,000 people suffering from poverty, mental illness, alcoholism, and other problems. The residents of the Infirmary helped maintain farmlands at and around the facility. By 1932, the Infirmary was serving more than 4,000 patients, including over 500 with tuberculosis.
