Whether you hire a few people each month or manage a large intake, a clear collection process helps candidates complete the right test. Smart Labs Now supports employers, recruiters and staffing firms across Portland, Beaverton, Hillsboro, Gresham and the surrounding metro area through our two Portland locations and mobile collection by arrangement.
The panel number alone does not tell you everything included in a test. Before ordering, confirm the substance list, THC requirements, specimen type, screening method and any laboratory confirmation or medical review requirements. We match collection to the authorized order; your organization sets its hiring policy.
Need testing for a regulated driving position? See our DOT and commercial driver testing services. DOT drug tests use laboratory processing; instant drug screens are not a substitute.
Ask about on-site mobile collection for group hiring, seasonal recruitment or scheduled workforce testing. Tell us the site address, number of people, required tests and preferred date so we can confirm staffing, collection space and fees.
Do not rely on the panel count alone. We confirm the substances included in your specific order, including whether THC is included, before collection.
Walk-in collection is available for eligible services during business hours. Candidates should follow their employer’s authorization, location and deadline. Contact us first for group collections, observed tests or special requirements.
Request a quote based on your panel, method, monthly volume and collection location. We explain applicable collection, laboratory, confirmation and mobile-service charges before you proceed.
