What Makes Brentwood Testing Different
An office-heavy market
Brentwood has a large concentration of corporate offices, especially around Maryland Farms. Office employers often need pre-employment screening and background checks more than on-site collection. Online ordering handles both without a visit from a collector.
Healthcare administration
Healthcare companies based in Brentwood may require expanded panels, background checks, or specific documentation for certain roles. Confirm the policy before choosing a panel.
Formal programs for growing companies
As a company grows, a written drug-free workplace policy helps set consistent rules for pre-employment, random, reasonable-suspicion, and post-accident testing. ReliaLab Test employer accounts can support each of those testing reasons.
The Brentwood testing advantage
- Employer accounts for ongoing programs
- Quest Diagnostics and Labcorp collection options
- Drug testing plus background checks
