Why Employers Use Pre-Employment Drug Tests

Pre-employment drug testing helps reduce risk, support a drug-free workplace culture, and improve safety—especially in roles involving vehicles, heavy equipment, patient care, public interaction, or sensitive data. Testing is typically performed after a conditional offer and before the first day of work, consistent with common hiring best practices and applicable laws.

Common Test Types for Pre-Employment Screening

Urine Drug Testing
A widely used option for workplace screening with flexible panel choices (e.g., 5-panel, 10-panel).
Hair Follicle Testing
Longer detection window that can help identify patterns of use over time.
Oral Fluid (Saliva) Testing
Convenient collection method with options for rapid screening or lab testing.

How the Process Works

1) Order & Schedule
Choose your test, then select a local collection site or request mobile testing at your workplace.
2) Secure Collection
Identity verification and controlled collection procedures help protect integrity and confidentiality.
3) Lab Testing (When Selected)
Specimens are processed by certified laboratories based on the program requirements and your order.
4) Results Reporting
Results are reported securely. For lab-based workplace testing, an MRO review option may be used to verify results.

Compliance Notes (Important)

  • Laws can vary by state and locality. Your written policy should define who is tested, when testing occurs, what substances are included, and how results are handled.
  • Many employers conduct drug testing after a conditional offer and apply the process consistently for the same job category.
  • Marijuana rules and disability accommodation considerations may apply depending on jurisdiction and role. If you need help aligning a program to your locations and workforce, we can assist.

Pre-Employment Drug Testing FAQs

What is a pre-employment drug test?

A pre-employment drug test is a screening ordered by an employer to help evaluate whether an applicant has recently used certain drugs before starting work. Employers typically apply testing consistently under a written policy.

When should an employer test an applicant?

Many employers test after making a conditional offer and before the employee's first day, while applying the same process for applicants in the same job category and following applicable state/local laws.

Which test is best for pre-employment screening?

It depends on your goals. Urine testing is common and cost-effective, hair testing can provide a longer detection window, and oral fluid testing can be convenient for on-site programs. We can help you choose based on role risk and policy.

How fast can I schedule a test?

Same-day appointments are often available depending on your location and the collection site schedule. Online ordering is available 24/7.
