SAPP Drug Screening Lab is a mobile urine specimen collection service based in Cincinnati, Ohio. We specialize exclusively in DOT and Non-DOT urine specimen collections for employers and regulated workplaces. We are DOT-qualified urine specimen collectors committed to maintaining strict chain-of-custody procedures and professional documentation suitable for workplace audits.
We are not a laboratory. Laboratory analysis and Medical Review Officer (MRO) services are coordinated through certified laboratory partners and employer-designated TPAs to ensure fully compliant reporting.
Our mission is to support safer and more compliant workplaces by delivering reliable, mobile urine specimen collection services with professionalism and integrity.
Contact us to schedule a DOT or Non-DOT urine specimen collection at your workplace or designated location.
A DOT-qualified collector arrives on-site and performs the urine specimen collection following strict chain-of-custody procedures.
Specimens are securely prepared and transferred to certified laboratory partners for analysis and MRO review as required.
Results are reported through certified laboratories and employer-designated TPAs in full compliance with DOT and workplace regulations.
