Why Employers Choose Our On-Site Team

HR and safety leaders often reach out to us after dealing with missed shifts, overtime, and frustrated employees caused by off-site appointments. Our mobile service is built to reduce that disruption. Our collection staff comes to your workplace, which helps you keep employees on the clock and close to their workstations.

Certified Collectors & Secure Sample Handling

Our team is trained in standard collection procedures for workplace drug and alcohol testing. We pay careful attention to chain-of-custody steps, labeling, and documentation so results are handled accurately and securely. Employees are treated with respect throughout the process, which supports morale and reduces tension around testing events.

Flexible Scheduling Around Your Operations

Whether you’re coordinating around production lines in an industrial park on the edge of Sioux Falls or managing office staff downtown, we work with you to find collection times and locations that fit your operations. We also talk through peak periods, shift patterns, and scheduling constraints. Communication stays clear from initial scheduling through final reporting.

On-Site Drug Testing in Sioux Falls

Many employers look for an on-site drug testing company in Sioux Falls because they want consistent screening without constant trips across town. We support a variety of drug testing needs so you can align your program with company policy, industry expectations, and safety goals.

We support common workplace testing situations:

• Pre-employment screens
• Random selection programs
• Reasonable suspicion testing
• Post-incident checks
• Follow-up schedules when required by your policies

Our team works with your designated contact to understand which employees should be tested and when, then structures the visit around that plan.

Types of Samples We Can Collect at Your Site

Depending on your program, we can collect urine, oral fluid, or hair samples. Each option differs in detection window, collection experience, and suitability for a particular employer policy. We explain these options in practical terms so you can select what fits best for your organization. Regardless of method, we focus on consistent procedures and clear documentation for every collection.

After collection, we handle samples according to your testing program and send results securely to the contacts you identify, such as HR or safety management. You can then apply those results within your existing policies and processes.

On-Site Alcohol Testing for Workplaces

Some situations require immediate clarity about alcohol use on the job. On-site alcohol testing services cover post-incident checks, reasonable suspicion situations, and return-to-duty evaluations in safety-sensitive roles. In these moments, timely information supports safer decisions for everyone involved.

Our team conducts workplace alcohol testing using breath alcohol testing devices suited to employment screening. Testing typically takes place in a private, designated area at your facility, so employees aren’t placed on display during a sensitive situation. We explain each step of the process to the employee in clear terms to help keep the interaction calm and professional.

Because these events can be stressful for supervisors and employees, we move efficiently while following appropriate procedures. Results are shared with your authorized contact so you can act according to your policies and any applicable guidelines. For employers who already have a drug testing program in place, on-site alcohol checks can often be coordinated within the same visit when appropriate.

How Our Mobile Testing Process Works

Call to Schedule
When you first contact Fastest Labs of Sioux Falls, we discuss your workplace, the number of employees you plan to test, and the type of testing program you have in place. For local visits in Sioux Falls, we work with you to identify preferred dates, times, and any shift patterns that affect scheduling. This planning step helps minimize disruption once we arrive.

Our Team Arrives at Your Workplace
On the day of testing, our team arrives with the supplies and equipment needed for the scheduled collections. We typically set up in a restroom or other private space that you designate, making sure there is enough room for employees to move through testing in an organized way. Supervisors and HR contacts stay informed about progress so they can coordinate work coverage as needed.

Organized Sample Collections, Analysis, & Results
During each collection, our staff explains basic steps to the employee, completes required forms, and maintains chain-of-custody procedures. Once collections are complete, samples and documentation are handled according to your established program. Result timing depends on the type of testing you use and any laboratory involvement, and we communicate expected timeframes so you know when to look for updates.
