Drug Testing Types
Background Drug and Alcohol Check
This service immediately provides clients with an employee’s three-year history of previous drug test violations and also verifies if employees received proper education and/ or treatment for any positive results.
Conditional Employment (Pre-employment)
The applicant must pass a drug test prior to hire or as a condition of employment.
Post-Accident (24/7)
After an accident, all employees whose performance may have contributed to the accident must be tested according to company policy.
Reasonable Cause
An employee must submit to a drug test if two supervisors, at least one of which is trained in recognizing the signs and symptoms of drug abuse, observe performance and behavior which would indicate possible drug and/or alcohol use.
Random
A specified percentage of a company's covered workforce must be randomly tested each year for the presence of controlled substances or, in some cases, alcohol.
Follow-Up Testing
A reasonable program of unannounced drug testing can be implemented for an employee who has returned to duty after failing a previous drug test, or after refusing to submit to a drug test.
Periodic
The Department of Transportation requires some industries to test employees as part of a physical examination during the first calendar year of the implementation of the employer's anti-drug program.
