DOT and NON-DOT Reasons for Testing

Pre-employment testing • Random testing • Reasonable/suspicion testing • Post-accident testing • Return to work testing • Follow-up testing and much more.

Pre-Employment Testing – required prior to hiring an individual or prior to an individual being placed in or returned to a safety-sensitive position.  Pre-employment testing is also needed prior to employee being placed into a random pool. NON-DOT companies may also choose to require Pre-employment testing.


Random Testing – Employers who are subject to DOT regulations must randomly select and test a fixed percentage of their covered work force each year.  NON-DOT companies may also choose to require Random testing.


Reasonable Suspicion/For Cause Testing – If an employee is in a covered position and is suspected by his/her employer of using a prohibited drug, the employee may be required to submit to testing.  NON-DOT companies may also choose to require Reasonable Suspicion/For Cause testing.


Post Accident Testing – A covered employee may be required to submit for testing if the employee’s performance either contributed to or cannot be discounted as a contributing factor to an accident.  NON-DOT companies may also choose to require Post Accident testing.


Return To Duty Testing – If a covered employee refuses to provide a specimen or tests positive on a previous test, he/she must submit a specimen for testing before he/she may return to duty in a safety sensitive position.  NON-DOT companies may also choose to require Return to Duty testing.


Follow-Up Testing – An employee, who has returned to duty in a covered position after a negative return-to-duty test, may be required to submit to a series of unannounced tests.  NON-DOT companies may also choose to require Follow-Up testing.

le. Our national on-site team provides post accident, reasonable suspicion, random and return to duty drug and alcohol testing.

Urinalysis Testing

Sequential is a premier testing provider of urine drug and alcohol testing services. Urine testing, one of the most common testing methods, is an accurate and reliable way to detect casual or chronic drug use that may occure with in the past 24 to 72 hours. Our parent SAMHSA-certified laboratories administer urine drug analyses in accordance with DHHS and D.O.T. requirements. Our standard urine drug testing panels range from 5 drugs to 11 drugs with an in-depth test  to determine possible adulteration.

Sequential 6- Drug Lab Panel (AMP/THC/COC/PCP/OPI/CREATININE)


(Available in Rapid Test)


(Available in Rapid Test)

*An in-depth test for creatinine is performed on every specimen to determine possible adulteration. The THC/Creatinine ratio is provided on every final result.

 ETG Testing –Alcohol Consumption test

Ethyl Glucuronide (EtG) Testing – Detectable up to 80 hours after consumption!
Sequential tests urine to detect the consumption of alcohol.


The EtG test is a biomarker test that detects the presence of ethyl glucuronide in urine samples. Usually, testing is used to monitor alcohol consumption in individuals who are legally prohibited from drinking alcohol.

The EtG test is just one of many biomarker tests available to confirm the presence of alcohol in urine samples. Sequential method of testing is used to document abstinence and detect relapse, but it can also be used in clinical settings to screen for drinking problems, evaluate interventions for alcohol problems and motivate changes in drinking behavior.




Steroid Drug Testing Panel

Anabolic-androgenic steroids are manmade substances related to male sex hormones. “Anabolic” refers to muscle building and “and androgenic” refers to increased masculine characteristics. “Steroids” refers to the class of drugs.

Sequential offers anabolic steroid testing is to law enforcement, athletic programs and professional sports organizations. Our steroid testing is ideal for professional sports organizations, law enforcement and every day employees who may be exposed to using. Parents can also use this service if they believe their child may be using steroids. Sequential offers the same high quality test results for steroids, diuretics and stimulants as we do for DNA, urine, oral fluid and hair drug testing


Oral Fluid Drug Testing
 Sequential oral fluid drug test is a simple oral buccal swab of the mouth. It’s a simple method of saliva sample collected and tested. Test results are read within three to five minutes. The oral fluid collection is directly observed, making it less susceptible to specimen adulteration.
Due to the oral fluid specimens require much lower screening levels than urine, Sequential performs the initial screening test by enzyme-linked immunosorbent assay (ELISA) microplate technology. We also offer confirmation of presumptive positive screens using GC/MS. Sequential’ oral fluid drug test profile includes:

•Cannabinoid (THC)
•Opiates (codeine, morphine)
•Phencyclidine (PCP)
Sequential operates in one of the largest networks of patient service centers throughout the US with personnel trained in chain-of-custody protocol. Our extensive clinical support network provides employers and individual’s convenient access to patient services centers.

Ecstacy Drug Testing

Ecstasy (3, 4-methylendedioxymethamphetamine, or MDMA) is a party drug predominantly utilized at raves. In recent research the drug Ecstasy is moving beyond the club sceene and into everyday work environments. The adverse effects of MDMA include confusion, depression, anxiety, sleeplessness, nausea, sweating, dry mouth and blurred vision.

Sequential screens for MDMA like other workplace drug tests. Negative or positive results are reported within 24 to 72 hours of specimen collection. MDMA can be added as additional panel to your current 5 or 10 panel drug test. (available in rapid test)


Hair Test

A Sequential Medical Examiner cuts approximately 50-100 strands from the crown of an individual head or may cut from other areas of the body.  Our Laboratory provides a thorough analysis of the hair.
