Corporate Overview
On-site Screening, LLC (On-site), located in Broomfield, Colorado, is a premier provider of drug testing products and laboratory services nationwide.
Selling thousands of tests per month, On-site is one of the largest distributors in the nation of point-of-collection drug and alcohol tests. Each test is a lateral flow, chromatographic, immunoassay for the qualitative detection of drugs and their metabolites at specified cut-off concentrations. On-site’s test devices are able to detect drugs of abuse and alcohol in both urine and oral fluids. The immunoassays are based on the principle of competitive binding; drugs that may be present in the urine or oral fluid specimen compete against their respective drug conjugates for binding sites on their specific antibody.
Complementing its point-of-collection business, On-site also administrates corporate drug testing policies nationwide. As a third party administrator, On-site utilizes all the industry’s resources to build customized, comprehensive programs that meet individual business needs. Whether your agency requires accurate on-site devices, professional laboratory services, or both, On-site will tailor a program that is right for you. All of On-site’s programs are built on a foundation of solid customer support, competitive pricing, and adherence to industry standards.
On-site uses federally certified laboratories to deliver fast and accurate results. Urine, hair follicle, and oral fluid specimens are analyzed for drugs of abuse and alcohol by state of the art screening and confirmation methodologies, including: enzyme immunoassay (EIA), enzyme-linked immunosorbent assay (ELISA), radioimmunoassay (RIA), thin layer chromatography (TLC), gas chromatography (GC) and/or gas chromatography/mass spectrometry (GC/MS), liquid chromatography/mass spectrometry (LC/MS), and liquid chromatography/mass spectrometry/mass spectrometry (LC/MS/MS).
Servicing clients nationwide, On-site’s customers include: correctional, medical, and treatment facilities; probation and parole agencies; distribution, construction, and other private sector companies. On-site has the experience and resources to supply your agency with the highest quality products and services.
