The RI Witness™ System is widely recognised as the gold standard in IVF laboratory safety, enhancing accuracy, efficiency, and security in Assisted Reproductive Technology (ART) procedures. Since its introduction in 2007, this advanced electronic witnessing system has been trusted by leading fertility clinics across six continents to safeguard every step of our processes, ensuring unmatched precision and consistency. At Sims IVF, we are proud to utilise this innovative technology to streamline treatment workflows, help to minimise human error, and provide our patients with peace of mind throughout their fertility journey.

Why the RI Witness™ System Matters?

Mitigating Human Error
IVF procedures are intricate, and even minor oversights can have profound consequences. Traditional methods, such as manual checks, rely on human memory and vigilance and are vulnerable to fatigue or lapses. The RI Witness™ System offers continuous electronic monitoring, detecting potential mismatches before they occur, and significantly reducing the risk of human error.

Building Trust with Patients

At Sims IVF, knowing our patients’ samples are consistently validated through a reliable system provides both patients and clinicians with peace of mind.

Dr. James Richards, Senior Embryologist at Sims IVF, states -

“As an embryologist, I can confidently say that the RI witnessing system is an essential part of our laboratory. It gives us complete peace of mind by ensuring that every step of the treatment process is triple-checked and accurately matched to each patient. This advanced technology virtually eliminates the risk of human errors, enhances traceability, and allows us to focus on what matters most- providing the best possible care and outcomes for our patients.”

How does it work?

RFID-Based Tagging
Each patient and their samples, whether sperm, eggs, or embryos, are tagged using RFID technology. These tags securely bind the identity of the samples to the patient and are automatically tracked throughout the process.

Automated Monitoring
RFID readers are strategically placed across all lab workstations and integrated into our laboratory benchtops and incubator plates, and remain active around the clock. The system continuously monitors the presence and identity of all tagged items, ensuring nothing goes unchecked.

Instant Alerts
If an unlinked or mismatched sample enters our workstation, the system immediately triggers an audible and visual alert, preventing further action and allowing for intervention.

Full Traceability
Every tagged item and each user action is time-stamped and recorded, creating an unalterable audit trail. This enhances traceability and simplifies compliance and operational audits.

In a field where precision matters more than anything, at Sims IVF, the RI Witness™ System stands as a critical safeguard for our IVF and ART laboratories. It combines:

  • Continuous electronic monitoring to reduce risk
  • Streamlined workflow to boost efficiency
  • Robust documentation for audits and quality control
  • Patient and staff peace of mind rooted in proven safety and accuracy

Graham Coull, Scientific Director of Sims IVF, states -

“As Scientific Director of three busy laboratories, I consider witnessing the most essential aspect of routine laboratory practice. RI Witness provides full traceability of all samples at every workstation and doesn’t just alert us to a problem; it’s an early warning system that automatically warns us to potential issues before they actually arise. In addition to our manual double-witnessing procedures, RI Witness provides the highest-level traceability and security for both staff and patients seeking treatment in Sims IVF.”

As fertility treatments at Sims IVF continue to evolve, technologies like RI Witness™ are vital in ensuring that we maintain excellence in patient care, operational reliability, and regulatory compliance.
