The RPRI System: Same-Day Risk Scores. Faster Decisions.
Our Rapid Pathogen Risk Indicator (RPRI) technology combines molecular detection with proprietary risk scoring algorithms to give your QA team answers — not just data.
What Is the RPRI System?
The Rapid Pathogen Risk Indicator (RPRI) is Pure Food Labs' proprietary approach to combining real-time PCR detection with a quantitative risk scoring model. Rather than delivering a binary positive/negative result, RPRI gives your team a risk score that accounts for pathogen load, detection method sensitivity, and product-specific contamination thresholds.
The result: faster, smarter decisions — whether you're evaluating a hold/release call, responding to a potential recall situation, or monitoring an environmental monitoring program over time.

How RPRI Works
Sample Collection
Your sample arrives at our lab with a unique RPRI tracking ID. Chain-of-custody documentation begins immediately.
Molecular Detection
Real-time PCR and proprietary enrichment protocols detect target pathogens at ultra-low concentrations — below conventional method thresholds.
Risk Scoring & Report
Our algorithm calculates an RPRI score based on pathogen load, method performance, and product type. Results are delivered to your secure portal same day.
Where RPRI Makes the Difference
Hold / Release Decisions
When a batch is on hold, every hour costs money. RPRI same-day results let your QA team make release decisions based on data — not waiting.
Recall Risk Assessment
Early-stage contamination signals are often missed by conventional methods. RPRI higher sensitivity catches low-level contamination before it escalates.
Environmental Monitoring
Track pathogen risk across your facility zones over time. RPRI trending data identifies persistent harboring sites before they become product-affecting.
Supplier Qualification
Verify incoming raw materials before they enter your process. RPRI-scored supplier testing adds a quantitative dimension to your approved supplier program.
