Our local DOT drug and alcohol testing centers are located in Leaf MS and the surrounding areas providing DOT drug testing, DOT alcohol testing and DOT physicals for all DOT modes regulated by Part 40. Same day service is available at our Leaf MS DOT drug testing facilities and most of our DOT drug testing locations are within minutes of your home or office.
What type of DOT Testing is required?
Coastal Drug Testing provides DOT pre-employment, random, post-accident, reasonable suspicion and return to duty testing at our Leaf MS DOT drug testing centers.
If you hold a CDL license, a large, medium or a small trucking company, Coastal Drug Testing has a complete DOT compliance package which includes all the requirements to comply with CFR 49 part 40.
All Coastal Drug Testing DOT drug testing centers utilize SAMHSA Certified laboratories and a licensed Medical Review Officer as required by DOT part 40 regulations.
The U.S Department of Transportation (DOT) requires that all DOT regulated "safety sensitive" employees have a negative DOT pre-employment drug test result on file and be actively enrolled in a DOT approved random drug and alcohol random testing pool (consortium).
In addition, if a DOT regulated company has more than one "safety sensitive" employee, the employer must also have a written DOT drug and alcohol policy along with an on-site supervisor that must have completed a reasonable suspicion supervisor training program.
On the road and need a DOT Drug or Alcohol test? No Worries!
To be compliant with DOT regulations, a company's DOT drug and alcohol testing program must have the following components:
- Employee Drug Testing
- Written Drug and Alcohol Policy
- Supervisor Training
- Substance Abuse Referral
- Employee Education
- Random Selection Program
- Post Accident Testing
- Designated Employer Representative
- Federal Chain of Custody Forms
- Part 40 Regulations on File
The Department of Transportation (DOT) has specific drug and alcohol testing requirements for the all transportation modes all DOT agencies.
Our modes included are:
- Federal Motor Carrier Safety Administration (FMCSA)
- Federal Aviation Administration (FAA)
- Federal Transit Administration (FTA)
- United States Coast Guard (USCG)
- Pipeline and Hazardous Materials Safety Administration (PHMSA)
- Federal Railroad Administration (FRA)
Are You Enrolled in a DOT Consortium?
Individuals who are employed in a position designated as "safety sensitive" must be actively enrolled in a random drug and alcohol testing program. Oftentimes, covered employees will join a group of other DOT regulated employees in a random testing program and this is referred to as a DOT Consortium. Generally, an employer who has less than fifty employees or single operators will join the consortium which will comply with the random drug and alcohol testing requirements of 49 CFR Part 40. Employers that have over 50 employees who are regulated by Part 40 may elect to be enrolled in a "stand alone" random testing pool.
The DOT consortium is cost effective and complies with all requirements of 49 CFR Part 40 which mandates that all "safety sensitive" employees be enrolled in a random drug and alcohol testing program.
The Department of Transportation (DOT) has strict regulations requiring regulated companies and independent operators (CDL License Holders) to be an active member of a DOT drug and alcohol Consortium and failure to comply with these regulations can result in significant fines and other DOT sanctions.
We are fully versed in the DOT procedures for pre-employment drug testing, random drug testing, reasonable suspicion drug testing, post-accident drug testing, return to duty drug testing and follow up drug testing.
DOT regulated companies with multiple safety sensitive employees must also have an employee within the company who is assigned as the "designated employer representative" (DER). This is the person responsible for removing any DOT "safety sensitive" employee who is covered by 49 CFR Part 40 from performing a DOT safety sensitive position when a positive drug or alcohol test result has occurred or an employee has refused to take a required DOT test.
If you have recently become a DOT regulated company, within the next 18 months the Department of Transportation (DOT) will conduct a "new entrant" inspection to ensure that you are in compliance with all DOT regulations including the drug and alcohol testing requirements. If you are currently a DOT regulated company, you are subject to regular inspections to ensure compliance.
Avoid DOT fines, penalties and be complaint with all DOT drug and alcohol testing regulations! Coastal Drug Testing can assist small, medium and large DOT companies in complying with all requirements of 49 CFR Part 40.

Local Area Info: Liquid chromatography–mass spectrometry
Liquid chromatography–mass spectrometry (LC-MS) is an analytical chemistry technique that combines the physical separation capabilities of liquid chromatography (or HPLC) with the mass analysis capabilities of mass spectrometry (MS). Coupled chromatography - MS systems are popular in chemical analysis because the individual capabilities of each technique are enhanced synergistically. While liquid chromatography separates mixtures with multiple components, mass spectrometry provides structural identity of the individual components with high molecular specificity and detection sensitivity. This tandem technique can be used to analyze biochemical, organic, and inorganic compounds commonly found in complex samples of environmental and biological origin. Therefore, LC-MS may be applied in a wide range of sectors including biotechnology, environment monitoring, food processing, and pharmaceutical, agrochemical, and cosmetic industries.
In addition to the liquid chromatography and mass spectrometry devices, an LC-MS system contains an interface that efficiently transfers the separated components from the LC column into the MS ion source. The interface is necessary because the LC and MS devices are fundamentally incompatible. While the mobile phase in a LC system is a pressurized liquid, the MS analyzers commonly operate under vacuum (around 10?6 torr). Thus, it is not possible to directly pump the eluate from the LC column into the MS source. Overall, the interface is a mechanically simple part of the LC-MS system that transfers the maximum amount of analyte, removes a significant portion of the mobile phase used in LC and preserves the chemical identity of the chromatography products (chemically inert). As a requirement, the interface should not interfere with the ionizing efficiency and vacuum conditions of the MS system. Nowadays, most extensively applied LC-MS interfaces are based on atmospheric pressure ionization (API) strategies like electrospray ionization (ESI), atmospheric pressure chemical ionization (APCI), and atmospheric pressure photo-ionization (APPI).These interfaces became available in the 1990s after a two decade long research and development process.
The coupling of chromatography with MS is a well developed chemical analysis strategy dating back from the 1950s. Gas chromatography (GC) - MS was originally introduced in 1952, when A.T. James and A.J.P Martin were trying to develop tandem separation - mass analysis techniques. In GC, the analytes are eluted from the separation column as a gas and the connection with electron ionization (EI) or chemical ionization (CI) ion sources in the MS system was a technically simpler challenge. Because of this, the development of GC-MS systems was faster than LC-MS and such systems were first commercialized in the 1970s. The development of LC-MS systems took longer than GC-MS and was directly related to the development of proper interfaces. V.L. Tal'roze and collaborators started the development of LC-MS in the early 1970s, when they first used capillaries to connect LC columns and MS ion sources. A similar strategy was investigated by McLafferty and collaborators in 1973. This was the first and most obvious way of coupling LC with MS, and was known as the capillary inlet interface. This pioneer interface for LC-MS had the same analysis capabilities of GC-MS and was limited to rather volatile analytes and non-polar compounds with low molecular mass (below 400 Da). In the capillary inlet interface, the evaporation of the mobile phase inside the capillary was one of the main issues. Within the first years of development of LC-MS, on-line and off-line alternatives were proposed as coupling alternatives. In general, off-line coupling involved fraction collection, evaporation of solvent, and transfer of analytes to the MS using probes. Off-line analyte treatment process was time consuming and there was an inherent risk of sample contamination. Rapidly, it was realized that the analysis of complex mixtures would require the development of a fully automated on-line coupling solution in LC-MS.
