Pre-Employment Drug Testing

Pre-employment drug testing is a screening process that checks job candidates for the presence of drugs or controlled substances before they begin work. Employers use it to reduce workplace accidents, lower liability exposure, improve productivity, and build a safer, more reliable team. Studies consistently show that a tested and monitored workforce leads to better safety outcomes, stronger morale, and improved profitability.

Lab24 is a COLA-accredited collection site and laboratory located in Redding, CA at 475 Knollcrest Dr. We provide pre-employment drug screening for employers throughout Northern California, including Redding, Anderson, Eureka, Mt. Shasta, Yreka, and surrounding communities. Specimens are collected and processed on-site, no shipping to an out-of-state lab.

Lab24's standard panels screen for the most commonly abused substances, including marijuana (THC), cocaine, opiates and opioids, amphetamines, methamphetamine, PCP (phencyclidine), benzodiazepines, barbiturates, ecstasy (MDMA), methadone, and propoxyphene. Custom panels are also available to match your specific industry requirements or internal drug policy.

Results are typically available quickly, with most tests processed within 48 hours of specimen collection. Because Lab24 collects and processes specimens on-site at our Redding laboratory, there are no delays from shipping specimens across the state. Fast turnaround means your hiring process keeps moving.

No appointment is needed. Once your business is enrolled in our system, employees and job candidates can walk in during regular business hours, Monday through Friday, 8am to 4:30pm. This is especially convenient for random testing programs where unannounced testing is part of the policy.

A random drug testing program involves the unannounced, periodic testing of employees selected at random from your workforce. It is one of the most effective tools for maintaining a drug-free workplace and ensuring ongoing policy compliance. Lab24 manages random testing programs for employers throughout Northern California. Enrolled employees can simply walk in, no scheduling required.

Lab24 offers a full range of non-DOT employer drug testing services, including pre-employment screening, random testing programs, post-accident testing, reasonable suspicion testing, and return-to-duty testing. Whether you need a one-time screen or an ongoing compliance program, we can build a solution that fits your business.

Non-DOT drug testing refers to workplace drug screening that follows a company's own internal drug policy rather than federal Department of Transportation (DOT) regulations. It is appropriate for the majority of private employers whose employees are not in federally regulated safety-sensitive roles. Lab24 specializes in non-DOT drug testing services for businesses of all sizes.
