Pre-Employment and Post-Employment Drug Testing Solutions

Pre-employment drug testing services from Global Verification Network help you comply with applicable regulations and avoid the adverse effects of hiring individuals who use drugs. For companies subject to regulation by the state and federal governments and for those administering their own drug-free programs, Global Verification Network offers certified third-party administrator (C/TPA) pre-placement drug test services.

 Urine, hair and oral fluids are the most common types of tests performed — with urine and saliva offering the fastest turnaround of approximately 48 hours. With any method you choose, the Medical Review Officers at Global Verification Network review the results to verify accuracy, provide you with detailed records, and help identify any allowed uses of tested drugs. In addition, our Medical Review Officers can answer questions and provide any required instruction.

Legal & Compliance Requirements for Workplace Drug Testing

Workplace drug testing is governed by a complex framework of federal, state and industry-specific regulations. For transportation employers, the U.S. Department of Transportation mandates drug and alcohol testing for an estimated 6-8 million safety-sensitive employees across aviation, trucking, rail, transit, pipelines and maritime operations. These DOT-regulated programs impose strict requirements around testing circumstances, specimen handling, result verification and record retention to ensure public safety and regulatory compliance. 

Beyond transportation, many employers must comply with the Drug-Free Workplace Act, which applies to certain federal contractors and grant recipients. This law requires organizations to maintain drug-free policies, implement testing where applicable, and take appropriate action when violations occur. In addition, state laws often dictate when testing may occur, including pre-employment, post-accident, reasonable suspicion or random drug testing, as well as the conditions under which employers may enforce their policies.

When employers rely on third-party testing reports for employment decisions, Fair Credit Reporting Act (FCRA) requirements may apply. This includes providing clear disclosures, obtaining written consent and following proper adverse action procedures if test results affect hiring or employment status. Failure to meet these obligations can expose organizations to legal risk, making compliance-driven program design essential. 

Many jurisdictions also require clear notification and, for job candidates, a conditional offer of employment before testing is conducted. Written consent remains a cornerstone of compliant programs. At the same time, Medical Review Officers (MROs) play a critical role in protecting employee privacy and result accuracy. MROs verify laboratory findings, assess legitimate explanations such as a lawful prescription drug and resolve potential false positives before results are reported to employers, ensuring fairness while safeguarding sensitive medical information.

Benefits & ROI of Drug Testing Programs

When implemented thoughtfully, workplace drug testing programs can deliver measurable safety and financial benefits. Research cited by the SHRM Foundation has shown that injury rates dropped from 14% to 6% after the introduction of testing programs, highlighting the impact testing can have in reducing workplace incidents, particularly in safety-sensitive roles.

Testing programs also serve as a deterrent to substance misuse. By discouraging drug abuse in the workplace, employers can reduce accidents, minimize absenteeism and promote a more stable and focused workforce. Employees in well-regulated environments often report improved morale, knowing that safety standards are applied consistently and fairly. 

From a cost perspective, effective testing programs can lead to meaningful savings. Fewer injuries translate into lower workers’ compensation claims, reduced lost-time incidents and decreased healthcare expenses tied to substance-related accidents. Over time, organizations also benefit from improved productivity and retention, as safer operations reduce disruptions and turnovers, limiting the need for repeated hiring or retraining. 

While academic research on testing effectiveness shows mixed results in some low-risk environments, evidence consistently suggests that targeted programs in high-risk positions produce stronger safety gains. The key lies in program design: aligning testing methods, frequency and oversight with actual workplace risk rather than applying a one-size-fits-all approach.

Our Drug Testing Services

As your trusted drug screening company, we provide random program notification, laboratory analysis, Medical Review Officer (MRO) services, chain-of-custody forms (paper or electronic) and collection site management on a nationwide basis. Urine (collection site or instant), hair and oral options are available. Online access to each program is available for reporting and random pool management.

Global Verification Network professional drug screening services include facilitation of sample collection at our partners’ multiple locations, shipment of the sample to the laboratory, MRO services (if applicable) and reporting of the drug test results.

  • Urine Drug Screen. This test determines if a candidate or employee is drug-free. We offer 5-, 7-, 9- or 10-panel urine drug testing through one of our partner labs. Requests for additional panels can be accommodated.

  • Hair Drug Screen. Hair drug testing offers the longest detection period for the most commonly tested drug types. It detects use between one week and three months from the date of drug use. Plus, this option prevents attempts at specimen substitution.

  • eCup/Instant Urine Drug Screen. This 5-panel option offers faster urine drug test results while eliminating the risk of human error. eCup is a “smart” cup that provides rapid screening without human intervention or interpretation. Negative sample results are available within an hour, which reduces testing turnaround time if no drugs are detected.

  • Oral Fluid Drug Test. This alternative allows donors to collect and cap their own samples on site in the presence of a monitor. This minimally invasive, easy-to-use method reduces tampering attempts and is particularly useful for detecting recent drug use or prolonged substance abuse. Because the results indicate if drugs are present at the time of collection, the oral test is especially suited for post-accident testing.
