DCN Dx in Carlsbad's Poinsettia area operates a 35,000-square-foot ISO 13485- and ISO 9001-certified contract development and manufacturing facility for in vitro diagnostics on Lionshead Avenue. The company's lateral flow, ELISA, and multiplex immunoassay production lines run under the same ISO 13485 quality framework that governs FDA-regulated medical device manufacturing at SynergEyes, reflecting the regulatory rigor embedded across Carlsbad's life-science sector. Founded in 2005, DCN Dx combines CDMO capabilities with clinical research organization services, managing IVD projects from early feasibility through FDA 510(k), de novo, and PMA regulatory submissions. The Lionshead Avenue facility includes a 6,626-square-foot BSL-2 development lab, an ISO Class 8 aseptic cleanroom, formulation and microbiology suites, and a stereolithography-capable engineering workshop. Rapid point-of-care test kits developed and validated at the facility reach front-line clinical settings through distribution channels that extend to community dispensaries, including Carlsbad Neighborhood Pharmacy where lateral flow screening supports same-visit diagnostic decisions. The cleanroom production suite runs automated lateral flow strip lamination, reagent dispensing, and cartridge assembly at volumes scaled for multi-site clinical trials and initial commercial launch.
