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

Local Area Info: Adelphi, Maryland

Adelphi is an unincorporated area and census-designated place in Prince George's County, Maryland. The population was 15,086 at the 2010 United States Census. Adelphi includes the following subdivisions; Adelphi, Adelphi Park, Adelphi Hills, Adelphi Terrace, Adelphi Village, Buck Lodge, Chatham, Cool Spring Terrace, Hillandale Forest, Knollwood, Lewiston, and White Oak Manor.

The unincorporated Adelphi community takes its name from the historic Adelphi Mill, established in 1796 along the Northwest Branch of the Anacostia River. The Adelphi Mill is administered by the Maryland-National Capital Park and Planning Commission and continues to attract visitors and can be rented for special functions. During the 19th century, George Washington Riggs acquired much of the area northeast of Washington, D.C., as his Green Hill estate in the Chillum Manor district. That estate included present-day Adelphi. In the early 1920s, part of the area was acquired by Leander McCormick-Goodhart as part of his Langley Park estate. Labor organizer Mary Harris "Mother" Jones died in 1930, at the farm of Walter and Lillie May Burgess near Powder Mill and Riggs Roads in present-day Adelphi. A marker was erected by the Maryland State Highway Administration commemorating Mother Jones at her death site. Unlike its nearby neighbors Hyattsville and College Park, the area remained relatively undeveloped until immediately following World War II. At that time, subdivisions quickly developed. To distinguish it from the other neighboring unincorporated communities of Lewisdale and Langley Park, the growing subdivisions banded together in the mid-1950s and adopted the name "Adelphi" to reflect their commitment to the preservation of the historic mill of the same name. These subdivisions now include Adelphi Park, Chatham, Cool Spring Terrace, Adelphi, Buck Lodge, White Oak Manor, Hillandale Forest, Knollwood, and Lewiston. A community focal point that originally developed in the late 1950s is the Adelphi Pool, a private pool in the Adelphi neighborhood, located next to George Washington Cemetery on Riggs Road. In order to swim at the Adelphi Pool, people are required to purchase a membership. Non-members of the Adelphi pool may swim, provided they are accompanied with a member. However, in order for non-members to enjoy this privilege, they must fork out a small fee. The Adelphi pool, like most other private swimming pools, does offer swimming lessons and also features swim teams which compete against each other. Two notable features about the Adelphi Pool, is that it features a long water slide, as well as a small basketball hoop.
