Protecting You

With RFID technology, every ID is totally unique and cannot be misread, making the RI Witness system both a reliable replacement to manual double witnessing as well as a solution for reducing staff distractions.

RI Witness readers and touch screens are installed at every work area, both inside and outside the lab, where patients or patient samples are treated.

Self-adhesive RFID tags are available to fit containers such as Petri dishes or test tubes that contain patient samples.  These tags enable the readers to register the containers in the work area and monitor a patient’s identity at every stage of the treatment.

The RI Witness RFID technology has been proven safe in mouse embryo tests continued up to the second generation and each batch of RFID tags is MEA tested.

RI Witness has been installed in over 86 labs worldwide and has been operating constantly since 2007 (24 hours, 7 days a week) with over a million embryos safely guarded.

The RI Witness system monitors every instance when gametes or embryos are transferred from one container to the next and ensures that only one patient can be worked on, at one workstation, at  one time, safeguarding sample identity.

In addition to the critical detection and prevention of human errors, RI Witness allows assessment of staffing levels, time keeping, productivity, competency, training and consumable traceability.  It can reduce staff distractions and stress, increasing staff efficiency, SOP compliance and auditing.  RI Witness is your indispensable ART management tool.


If at any time, samples from incompatible patients are introduced into the same work area, RI Witness warns the lab personnel both visually and audibly.

Monitoring is constant, so an identity check can never be overlooked.  It can even sound a warning if tagged containers are left inadvertently on a workstation.

RI Witness takes away the uncertainty, giving you increased confidence in all that you do.  It protects both you and your lab.


RI Witness will help you navigate through the wealth of information it collects in easy to read reports.

It can collate details of who has worked on a sample, when and at which workstation. It records sample images and procedural films, can audit the consumables or media used in a cycle, and it allows you to make considered decisions on how to improve your lab management.

It can even tell you where tagged patient notes were last located.


With the Imaging feature, you are able to capture images and videos from every microscope in the laboratory, at every stage of the patient cycle, in real time.  All the latest information on a cycle can be accessed immediately from any networked PC.

This imaging software is designed for visual assessment using digital zoom functions and for recording footage of laboratory procedures using sophisticated reporting functions. It is suitable for both patient records and research applications.

Giving Confidence

A picture of the embryo and the patient identity can be displayed in the transfer room giving the patient 100% confidence and reassurance.



Most labs record cycle information on paper forms which then need to be separately transcribed into a computer database.

The Data Capture feature enables you and your colleagues to enter data into patient records using small touch screen displays or a keyboard and mouse interface installed at work areas.

By inputting directly, transcription errors are minimised and multiple data handling is avoided. Data can be accessed and analysed immediately from anywhere on the system.

RI Witness™ makes the paperless laboratory a reality.

Prompting And Guiding

To aid a smooth workflow, many labs have installed the live cycle overview display board to show the cycle type and the last or next procedures performed or scheduled for that day.

Positioned on the lab wall and on the Lab Manager’s PC, the entire lab team gains an overview of the work for the day and how it is progressing throughout the day.


With its Cryo feature, RI Witness extends its reach to cryo storage allowing patient samples to be tracked as they enter and leave cryo, creating a complete record of a patient’s cycle.  The Cryo feature moves samples from the RI Witness RFID to cryo-suitable barcode identification using durable, lab proven Brady® labels to identify the vials or vitrification straws used.

The barcode labels are designed for visual assessment and have a proven record of durability and stability to extreme temperatures.  Cryo allows you to record the entry and exit of a sample from the cryopreservation process increasing your recording and reporting capabilities within RI Witness.


riwitness_64_traceabilityThe Traceability feature can help a clinic to keep a full record of consumables used in the laboratory, often a requirement of regulatory authorities.

Tailored to your lab protocols, this feature logs which products are used for specific processes or cycle types. Traceability records can be sorted or filtered in various ways to cross-reference patient cycles and batches of material.

As consumables are delivered to the clinic, they are entered into the Traceability database with details such as the relevant batch numbers and expiration dates, by scanning a barcode or manually inputting the details. Once registered, you simply tell the system when your lab starts using that batch and when you change to the next batch. When a batch is nearing its expiry date, you can set when you want Traceability to warn you, eliminating unnecessary waste or possible issues.

The quick and easy manipulation of the Traceability data means that the information can potentially be used to identify if any batches had a positive or negative effect on results. All records can also be exported to any spreadsheet software for further analysis and archiving.

Q: What is RFID?
A. RFID (Radio Frequency Identification) is a generic term for technologies that use radio waves to automatically identify objects. Labels with tiny microchips embedded into them are attached to all plasticware such culture dishes, test tubes, patient identity cards etc before being assigned to a patient. These microchips are read by the RI Witness™ sensors. There is no need to directly scan the labels, the whole process is automatic and many tags can be read simultaneously.

Q: How does the RFID label transmit the information?
A: RI Witness™ uses RFID tags and a reader. The reader sends out electromagnetic waves and the tag receives these waves. The RFID tag draws power from the field created by the reader and uses it to power the microchip’s circuits. The microchip then modulates the waves that the tag sends back to the reader and the reader converts the new waves into digital data.

Q: Are there any health risks associated with RFID and radio waves?
A: RI Witness™ uses a radio frequency similar to the signals received by your car radio. RI has organised exhaustive independant Mouse Embryo Assay (MEA) studies to demonstrate that RI Witness™ RFID does not have any detrimental effect on the development of embryos. These tests used radio waves which are 700 times stronger than those used by the actual product.

Q: Why is RFID better than using bar codes?
A: The most significant difference is that barcodes use line-of-sight technology . That is, a scanner has to “see” the barcode to read it, which means it is necessary to orientate the barcode towards a scanner for it to be read. Barcode systems therefore rely on the user remembering to make some kind of check to confirm patients’ sperm, oocytes and embryos match. This can be prone to human error, and if not done correctly, can give a false record.

Radio Frequency Identification, by contrast, doesn’t require line of sight. RFID tags can be read as long as they are within range of a reader. In addition, multiple RFID tags can be read at the same time, meaning that a whole collection of items can be identified together. RI Witness™ uses this ability to automatically check everything that is brought into the working area.

RFID technology provides a level of security that can eliminate human identification errors. RFID technology monitors everything in every work area, every second of every day. RFID offers an extremely large number of unique identities (UID). This means that each sample container can have its own UID and that procedures can be tracked in detail. The system knows exactly what has happened to the samples and which containers were used. Lastly, the communication between tag and reader is very secure.
