About Chaseville Road Labs
A Jacksonville-based, CLIA-certified molecular pathology laboratory built around clinical action.
Our Mission
Chaseville Road Labs exists to give referring clinicians the diagnostic data they need to act — quickly, clearly, and with confidence. Our menu spans three disciplines under one roof: validated multiplex PCR for infectious disease, LC-MS/MS toxicology for medication monitoring and substance use, and a full clinical chemistry and hematology service for routine blood work.
On the molecular side, we run validated PCR panels covering the conditions providers see most — respiratory, gastrointestinal, urinary, sexually transmitted, wound, vaginitis, and fungal infections — each reported as clear Detected / Not Detected calls per target. Our toxicology program pairs immunoassay screening with LC-MS/MS confirmation and quantitation across opiates, benzodiazepines, stimulants, and prescription classes, with analyte-level cutoffs designed for clinical decision-making. Our chemistry and blood service covers metabolic and lipid panels, hematology, thyroid and hormone testing, cardiac and inflammatory markers, and immunology — with specimen requirements and turnaround times built around the way clinicians actually order.
Every assay is designed and validated against the question a clinician actually needs answered at the point of care. We are an independent laboratory — not affiliated with a single health system — which lets us serve referring providers across Florida from a focused, modern diagnostic operation.
Behind the Name
Our name pays tribute to a piece of Jacksonville's history. The stretch of road now known as University Boulevard South traces back to the Arlington area, where its intersection with Arlington Road once served as a hub for the region's early wagon routes. Until 1959, that same roadway carried a different name — Chaseville Road — and we've carried it forward as a nod to the community we call home.
Our Laboratory
All testing is performed in-house on the Bio-Rad CFX384 real-time PCR system, a 384-well thermocycler optimized for high-throughput multiplex qPCR. Our panels are Laboratory Developed Tests (LDTs) validated under CLIA 42 CFR §493.1253, with ongoing quality control, calibration, and proficiency testing.
