About Us
Qualified collectors. Federal standards. No detour for your fleet.
AJ Signature & Screening Services, operated by Nectere Solutions LLC, was built around a simple premise: a required drug test shouldn't cost an employer a full shift of downtime. We bring qualified DOT specimen collectors to the vehicle, the yard, or the job site.
- Qualified DOT specimen collectors per 49 CFR Part 40
- Federal chain-of-custody documentation on every collection
- Direct observation and shy bladder procedures available
- Zero-downtime mobile dispatch model
Qualified Collector, AJ Signature & Screening Services
Compliance Standards
Every collection follows the same chain-of-custody discipline
Our collectors work to 49 CFR Part 40 guidelines for DOT specimen collection, with correct documentation, sealed transport, and a clear record from the moment a specimen is collected to the moment it reaches the lab. Non-DOT collections follow the same rigor, adapted to each employer's program.
This consistency is what allows us to operate on-site without compromising the integrity of a single specimen.
Why On-Site
Zero-downtime dispatch, built for commercial operations
No clinic wait
Drivers and operators stay with their equipment instead of sitting in a waiting room.
Scheduled around you
Collections are arranged around shift changes, dispatch windows, and route schedules.
Documentation you can trust
Every step is recorded to hold up to DOT and employer program scrutiny.
