Yes. EK‑DNA LLC provides mobile and on-site testing for employers, organizations, and individuals. We generally serve locations within 50 miles of Nashville, with extended mobile response available up to 100 miles when scheduling and service requirements permit.

Appointments are strongly recommended to confirm availability, testing requirements, pricing, and specimen-collection instructions. Mobile, after-hours, weekend, and post-accident services must be coordinated directly with our team.

We provide DOT and Non-DOT urine testing, instant drug testing, oral-fluid testing, hair testing, nail testing, alcohol testing, and specialized testing based on employer or individual requirements.

DOT testing follows federal regulations for employees working in safety-sensitive transportation positions. Non-DOT testing is governed by an employer’s workplace policy, applicable state law, and the testing program selected by the employer.

EK‑DNA LLC helps clients identify the appropriate collection process, but employers remain responsible for maintaining legally compliant workplace policies.

Yes. We provide mobile post-accident and reasonable-suspicion testing, including drug and breath-alcohol collections when required. Employers should contact EK‑DNA LLC as soon as possible so testing timeframes, location, documentation, and collector availability can be evaluated.

Yes. We provide DOT return-to-duty and follow-up urine collections. These collections are directly observed as required by federal regulations and must be supported by the proper employer, consortium, or testing-authority documentation.

The employee should bring:

• A valid government-issued photo ID
• Employer or testing-authority paperwork
• An electronic registration or donor pass, if provided
• Any additional documentation requested when the appointment is scheduled

The employee should not overconsume water before a urine collection because excessive fluid intake may result in a diluted specimen.

A standard collection may take approximately 15–30 minutes when identification, paperwork, and specimen requirements are completed without complications. Shy-bladder procedures, observed collections, documentation issues, or other special circumstances may require additional time.

Turnaround times depend on the test type, laboratory, shipping schedule, specimen validity, medical review, and whether confirmation testing is required. Instant-test results may be available shortly after collection, while laboratory-based testing generally requires additional processing time.

EK‑DNA LLC cannot guarantee a specific completion date unless it has been confirmed for the selected service.

Yes. EK‑DNA LLC assists employers with DOT and Non-DOT random-testing coordination. Program requirements depend on the employer’s industry, regulatory authority, workforce size, and written testing policy.

Our DNA-testing services include paternity, sibling, grandparentage, avuncular, twin-zygosity, ancestry, lineage, prenatal-paternity, immigration, forensic, and other relationship-testing options.

Legal DNA testing follows documented chain-of-custody procedures, identity verification, witnessed specimen collection, and laboratory requirements. Results may be suitable for court, child support, immigration, custody, or other official purposes.

Non-legal testing is intended for personal knowledge and generally cannot be used as legal evidence.

Yes. DNA-testing appointments and records are handled through controlled procedures designed to protect client privacy. Results are released only to properly authorized individuals according to the testing arrangement and laboratory requirements.

Turnaround times depend on the type of DNA test, laboratory processing, specimen quality, shipping schedule, and whether additional participants or documentation are required. Estimated turnaround times will be discussed when the test is scheduled.

Contact EK‑DNA LLC with the service needed, number of individuals, requested date and time, testing location, and whether the service is for an employer, legal matter, government requirement, or personal purpose.

Additional fees may apply for mobile response, extended travel, after-hours service, weekends, holidays, urgent requests, observed collections, shy-bladder procedures, or other specialized requirements. Pricing will be confirmed before service whenever circumstances permit.

Available payment options and payment deadlines will be included with the appointment confirmation or invoice. Employer-account arrangements may be available for approved business clients.
