How Electronic Witnessing Strengthens Identity Control in the Ivf Laboratory

Managing Risk Across the Specimen Journey | Part 1 of 5

Fertility centers are managing growing cycle volumes alongside increasingly complex laboratory workflows.

For laboratories, the priority is consistent identity verification supported by robust documentation that can be reviewed following any protocol deviation and used to confirm adherence to a clinic's standard operating procedures.

Identity Verification Must Scale with the Workflow

IVF laboratory teams perform identity checks across collection, fertilization, embryo culture, biopsy, cryopreservation, warming, and transfer. As the volume and complexity of these activities increase, so too do the opportunities for error, placing greater importance on the need for robust patient identity verification.

Matt Pettit, Chief Scientific Officer at Matcher, describes the challenge:

“As cycle volumes increase and workflows become more complex, fertility centres face the challenge of maintaining continuous identity verification across patients, reproductive specimens, consumable products, and procedural handoffs whilst fulfilling their responsibility to ensure safe and traceable laboratory practices.”

An effective system should help teams verify identity before the transfer of material occurs, capture the event in real time, and accurately record and retain data and information for compliance, audit readiness, and quality assurance.

Electronic Witnessing Adds a Digital Identity Control

Electronic witnessing uses digital identifiers to help confirm that the correct patient, specimen, and labware are matched at every step in the critical patient pathway.

Barcode-based verification reduces reliance on memory, handwritten records, and manual transcription. When these machine-readable identifiers do not match, the witnessing system provides a clear audiovisual alert, requiring the user to stop, record the reason for the mismatch, and repeat the verification procedure before proceeding with the workflow.

The resulting digital record can help establish:

Who performed the procedure
Who the patient was
What products and specimens were used
Where and when the activity occurred
The result of the match
Whether a near miss or protocol deviation occurred

This combination of verification and documentation provides quality managers and laboratory leaders with an auditable record of witness activity.

How Matcher Helps Reduce Risk

Matcher, part of Reprotech, is a barcode-based electronic witnessing, labelling, workflow scheduling, traceability, and insights system developed for fertility centres and donor banks. Matcher is available worldwide.

The system helps IVF professionals confirm patient and specimen identity before material is transferred through:

Barcode-based identity verification
Immediate visual and audible mismatch alerts
Time- and date-stamped photographic records
Configurable workflow process maps

Auditable records, including time- and date-stamped photographic evidence, document the who, what, where, and when of every witness step, while process maps can guide users through configured workflows and retain a record of overrides, skipped steps, or deviations.

Matcher also supports unique barcode identifiers down to the individual embryo, well, or microdroplet level, enabling centers to label, identify, select, and match the same correspondingly numbered embryos, biopsies and vitrification devices within a procedure.

Matcher Insights™ organizes captured information into dashboards and reports that can support auditing, workflow review, root-cause analysis, and continuous improvement.

Matt Pettit explains the operational value:

“Together, these controls help teams verify that the correct patient, specimen, procedure, and labware are matched throughout every workflow step, without any gaps, whilst at the same time creating an auditable record of witnessed activities.”

These capabilities support trained laboratory teams in reducing the risk of errors and adhering to established standard operating procedures. They do not replace professional judgement, clinic governance, or the laboratory’s quality-management responsibilities.

Professional Guidance Reinforces the Role of Traceability

The need for robust identification and witnessing is reflected in current professional guidance.

The 2026 ASRM committee opinion identifies multiple misidentification risk points during IVF cycles. It states that patient samples should remain identifiable and traceable, and it provides guidance on witnessing procedures, protocol-deviation reporting, and risk mitigation.

The 2026 ESHRE recommendations similarly address patient identification, reproductive-cell traceability, quality management, embryo biopsy, cryopreservation, and laboratory safety.

These organizations do not endorse or require a particular commercial platform. Their guidance provides an independent framework for evaluating identification, witnessing, documentation, traceability, and quality oversight.

Matcher supports these priorities by translating electronic witnessing into practical workflow controls.

Matcher’s Role Within Reprotech

Matcher supports the laboratory witnessing and traceability stage within the end-to-end digital chain of custody provided by Reprotech's broader specimen-management portfolio.

Once specimens enter onsite cryostorage, operational responsibility expands to digital specimen identity, inventory location, storage activity, and retrieval. That next stage is supported by TMRW Digital Specimen Management.

Each capability addresses a distinct stage of the specimen journey. Greater continuity across these stages remains part of Reprotech’s developing product vision and may require additional integration work.
