When environmental contamination compromised PCR accuracy and threatened a total diagnostic shutdown, the ROZOR Disinfection Robot provided a clinically validated, chemical-free intervention—restoring biosafety and operational continuity in just two hours.
Diagnostic Accuracy at Risk
A high-volume tertiary hospital in Istanbul faced a critical breach in environmental controls within its third-floor molecular pathology and microbiology laboratories.
- The Problem: Persistent aerosolized and surface-bound contaminants led to a spike in “false positive” PCR results, rendering testing unreliable.
- The Impact: Potential misdiagnosis and a looming threat to the hospital’s clinical accreditation. The Infection Control and Microbiology teams required a “Day 0” solution to prevent a full facility closure.
- The Barrier: Traditional procurement for high-end medical equipment typically involves lengthy tender cycles. To bypass this, the hospital utilized ROZOR’s Robot-as-a-Service (RAAS) commercial model, allowing for immediate deployment as an operational service rather than a delayed capital purchase.
Clinical Decision: Why ROZOR UVC Over Hydrogen Peroxide Vapor (HPV)?
The hospital’s technical committee, including Microbiology and Procurement Leads, evaluated Hydrogen Peroxide Vapor (HPV)—the traditional “gold standard”—but ultimately selected the ROZOR Disinfection Robot for three clinical and operational reasons:
| Feature | Hydrogen Peroxide Vapor (HPV) | ROZOR Disinfection Robot (UVC) |
| Turnaround Time | 6–10 hours (Sealing, gassing, aeration). | ~60 minutes (Immediate room re-entry). |
| Material Safety | Oxidizing agent; can degrade sensitive optics. | Non-corrosive; safe for high-end PCR & NGS machines. |
| Residue | Leaves chemical “film” requiring manual wipe-down. | Zero residue; lab-ready immediately after cycle. |
| Workflow | Requires HVAC isolation and room sealing. | Autonomous navigation; no specialized room prep needed. |
Microbiology Insight: While HPV is an effective sporicide, its long aeration times would have paralyzed the diagnostic workflow. ROZOR’s UVC technology provided the high-log reduction needed for PCR-contaminating nucleic acids without the toxic chemical footprint or the risk of damaging expensive sequencing equipment.
The Solution: Autonomous UVC Eradication
The ROZOR robot was deployed to the third floor to execute a targeted decontamination protocol. By moving autonomously through the space, it ensured high-intensity UVC light (254nm) reached every corner, eliminating the “shadowing” effect common with fixed UVC lamps.
Technical Highlights:
- Vision & LiDAR Mapping: The robot mapped the complex laboratory layout in minutes, ensuring 360-degree coverage around delicate centrifuges and workstations.
- Validated Cycles: Pre-programmed protocols calibrated specifically for DNA/RNA amplicon decontamination and multi-drug resistant organisms (MDROs).
- Digital Audit Trail: The system generated instant “Certificates of Disinfection,” providing the Infection Control Committee with the empirical data required to authorize the tracking and reopening.
The Outcome: Precision and Safety Restored
Within two hours of arrival, the ROZOR system completed its protocols.
- Zero Downtime: Laboratory operations resumed the same afternoon; a projected 48-hour manual deep-clean and gassing shutdown was avoided.
- Validation: Post-disinfection environmental swabbing confirmed the elimination of the contaminant, restoring 100% confidence in PCR results.
- Financial Impact: The hospital avoided the significant revenue loss and logistical burden of redirecting thousands of samples to external laboratories.
Expert Testimony
“Significant air and surface contamination affected the accuracy of PCR test results, leading to the temporary closure of the third floor. By utilizing ROZOR’s autonomous UVC technology, we achieved a level of decontamination that manual cleaning simply couldn’t reach. We eliminated the threat in two hours and secured our diagnostic integrity.”
— Infection Control Lead, Tertiary Hospital, Istanbul
The ROZOR robot isn’t just a tool; it’s a bridge between clinical safety and operational efficiency. By utilizing a service-based commercial model, the hospital obtained:
- Immediate Access: No waiting for capital budget approval during an active crisis.
- Operational Excellence: Reduced labor costs associated with manual terminal cleaning.
- Future-Proofing: Access to the latest autonomous navigation and UVC dosage software.
