A high-complexity, CLIA-certified and CAP-accredited laboratory dedicated to your study.
The lab
A lab team dedicated to your study.
RDI's laboratory handles clinical and research specimens under the same quality system and with the urgency diagnostic studies require. It also serves as the central biobank and logistics hub for our sites and sponsors — assembling kits, receiving and accessioning specimens, completing required testing, and storing samples according to protocol. Our laboratory staff works alongside the clinical team, taking work off the sites and making it easier for them to participate in the study.
Dr. Michael Samoszuk
Chief Scientific Officer & Medical Director
MD, pathologist
Owns the science and testing — a pathologist directs specimen handling and assay work, not a project manager.
Lara Flores
Chief Operating Officer
Owns execution across every active study — the operational lead from kit-out to database lock.
Kits assembled to the protocol and distributed by site.
Every specimen checked, accessioned, and tracked on arrival.
Testing and storage managed under the same quality system.

What we manage
What we manage here.
Reference testing
RDI provides high-complexity reference testing for physicians and sponsors through its own test menu. When specialized testing sits outside our menu, we coordinate send-outs through qualified national and specialty reference laboratories.
Laboratory site for analytical and clinical validation studies
Sponsors can place instruments in our laboratory and use RDI as an assay validation site. Our medical director can serve as the site principal investigator, and our technologists can be trained on the sponsor's system, assay, and protocol.
Study logistics and storage
Our laboratory team is the operating center for RDI's prospective collections. They assemble and distribute collection kits, receive and accession specimens, complete quality checks and required testing, and prepare samples for storage or shipment. They work in lockstep with the clinical team so the right sites have the right kits at the right time.
Remnant sample sourcing
Through RDI's own testing and qualified partner laboratories, we have access to over 2 million leftover specimens and can match the study's matrix, analyte range, positivity, volume, stability, and documentation requirements.
Relevant proof
Proof from the bench.
Time-critical specimen logistics
Four hours from vein to instrument.
A multi-analyte stability program required specimens to be collected, transported, processed, and tested inside a four-hour window and then tested over two years. RDI built the collection workflow around that deadline and ran the work on three sponsor-placed analyzers in Van Nuys.
186,300 timepoints · 3 analyzers · 4-hour window
Critical central-lab for time-sensitive study
Twenty-seven sites. One lab. One results stream.
For a national PSA study, RDI became the single specimen-and-results hub for 27 urology practices across the US — the team ensured samples were tested and entered into the EDC in real time, as the value was critical for study inclusion criteria. Few labs are equipped with a full lab team and research-aware coordinators.
