This is a real operating theatre. Every surface was cleaned to standard. Under BioTorch™ 445nm forensic detection — this is what was missed.

The Reveal

What Your Audit
Is Not Measuring.

A surgical equipment handle from a US operating theatre. Under normal light it appeared clean. Under BioTorch™ 445nm forensic illumination — it was not.

Detect. Investigate. Decide. Fluorescence indicates organic residue. BioTorch™ shows you where to look — your team decides what to do next. This is not a cleanliness detector. It is a forensic tool.

Real Evidence · Operating Theatre Environment

Every Surface.
Every Contact Point.

Six images. One operating theatre. Cleaned to standard. Under BioTorch™ 445nm — this is the evidence your current audit process cannot produce.

The DICE Protocol

D01

DETECT

BioTorch forensic illumination combined with ATP testing. Pinpoint critical contamination sites. Enhance cleaning precision with instrument-grade evidence.

I02

IDENTIFY

Rapid molecular diagnostics. Lateral flow and LAMP devices. Detect specific infectious agents beyond what fluorescence alone can confirm.

C03

CLEAN

Data-informed decontamination. Focused intervention based on what DETECT and IDENTIFY found — not assumption. Targeted. Verifiable. Defensible.

E04

EXAMINE

Ongoing verification through forensic illumination, ATP, and protein testing. Continuous improvement loop. Compliance evidence at every step.
