RCDA Testing in Chula Vista provides drug, alcohol, and DNA testing services from its Palomar Street location in the Broadway Corridor, operating as a designated Quest Diagnostics Preferred collection site and Fieldprint biometric enrollment center. Specimen processing runs through a network of CLIA-certified reference laboratories including Quest Diagnostics, FormFox, Vault Health, USDTL, and Psychemedics, covering urine, hair, nail, blood, and oral-swab matrices for both DOT and non-DOT panels. Founded as a Latino-owned enterprise, the operation handles court-admissible legal paternity and maternity DNA testing listed on the San Diego Superior Court's provider resource directory, as well as non-legal peace-of-mind testing with chain-of-custody documentation. Employer random-testing programs, taxi and cab license renewal screenings forwarded to the San Diego County Sheriff's Department, and probation diversion drug panels position the lab alongside walk-in collection operations such as Fastest Labs of Chula Vista on H Street. The testing menu extends to prenatal paternity analysis beginning at the seventh week of gestation, infidelity detection panels, and DOT-approved Evidential Breath Alcohol Testing using BAT-certified instrumentation.
