RCDA Testing operates a walk-in drug, alcohol, and DNA testing laboratory in Allied Gardens, San Diego at 4410 Glacier Ave #101, 92120, on the commercial block between Waring Road and Fairmount Avenue. The San Diego facility is the second location for this independently owned company, which also runs a collection site at 319 Palomar St in Chula Vista and was featured on CBS 8 San Diego covering its expansion into the Allied Gardens corridor. Testing services cover DOT-mandated screenings under 49 CFR Part 40 for commercial drivers, non-DOT workplace panels for private employers, PUC drug and alcohol testing for taxi and rideshare license renewals with results transmitted to the San Diego County Sheriff's department, and court-ordered probation testing for county diversion programs. Specimen collection methods include urine, hair follicle, oral swab, nail, blood draw, and breath alcohol, spanning detection windows from 24-hour breath alcohol to 90-day hair follicle panels. RCDA holds Quest Diagnostics Preferred status and processes specimens through FormFox Marketplace, Vault Health, E-Screen, Psychemedics, USDTL, CRL, DDC, Drug Scan, and Abbott laboratory networks. Employers in the Allied Gardens and Grantville commercial corridors who need additional specimen-collection infrastructure coordinate with Labcorp on the Kaiser Permanente Vandever campus for supplemental laboratory services. DNA paternity testing is available in both legal court-admissible and non-legal formats, with legal tests following chain-of-custody protocols that meet San Diego Superior Court evidentiary standards. RCDA appears on the San Diego County Superior Court's official Program Resource List for both drug testing and paternity testing, a designation requiring court approval of collection and reporting procedures. The Glacier Avenue office provides bilingual English and Spanish services, wheelchair-accessible entry, and gender-neutral restrooms. Non-invasive prenatal paternity testing is available as early as the seventh week of pregnancy through a maternal blood draw. Mobile collection crews travel to San Diego County job sites for on-location employer testing, post-accident collections, and random program draws. Fieldprint fingerprinting and I-9 employment verification are also processed at this FMCSA-registered Identogo collection site, and PROVISION PHARMACY on Waring Road handles prescription verification documentation for MRO review in the 92120 corridor. Walk-in specimen collection closes 30 minutes before the posted end of business hours, with the last specimen accepted 15 minutes before close.
