What is gamete mixing How do doctors avoid it

Have you ever heard of gametes jumbling in an IVF lab? It may seem amusing to some, but it may have serious ramifications for emotionally attached patients who come with the expectation of having their biological child. As a result, it should be avoided at all costs. As a result, a conventional safety strategy of double-checking approach or human witnessing method is used to reduce the likelihood of such errors. It is a manual double witnessing approach in which one embryologist sees another embryologist in action throughout the laboratory processes.

Collecting oocytes and sperm, Preparing and combining sperm, Transferring embryos into tubes or pipes, and transferring gametes into cryostorage are all crucial parts of laboratory techniques. Embryologists are exceptionally cautious and perfectionists, and by using two witnesses, they limit the likelihood of biological sample mixup. Is this control system, however, effective enough? After all, embryologists are just people who are prone to making mistakes at the end of the day. This is when The RI Witness enters the fray. It is an automated technology that assures crucial detection, eliminates the potential of human mistakes, and increases IVF laboratory efficiency.

What exactly is the RI Witness System?

RI Witness is an Electronic Witnessing System.

RFID (Radio Frequency Identification) is a contemporary tool used by IVF clinical practitioners to actively avoid gamete mixing by monitoring all types of activity in the IVF Laboratory. It is a fundamental technology in which sperm, egg, and embryo sample containers and tubes are embedded with an RFID Tag, allowing embryologists to identify, monitor, and report every stage of the operation in the laboratory. Every patient pair is given an ID card with a unique personal code that encrypts the patient’s encrypted data throughout the IVF process, reducing the likelihood of a mixup.

Why is RI Witness used?

RI Witness is an automated system that monitors samples without the need for human intervention. It operates from the moment the patient is issued an RFID Tag until the completion of the IVF therapy. RI Witness simplifies the whole process and assures patients that the treatment is relatively safe. If an RFID tag mismatch occurs, everything comes to a stop with the sound of an instant warning, and the system locks itself. As a result, no labor-intensive manual witnessing offers exceptional protection against any mistakes or errors. In this approach, RI Witness helps reduce stress and boost patient confidence by providing greater clarity while aiding physicians and patients and maintaining a consistent and dependable process flow. RI Witness is a reliable technology, and the most outstanding IVF laboratories worldwide rely on it for error-free procedures.

How does RI Witness function?

RI Witness detects and monitors every activity in the IVF Laboratory using Radio Frequency Identification (RFID). This approach helps to limit the possibility of human mistakes in sample processing by associating the patient’s identification with the sperm, eggs, and embryos at each step of the IVF cycle. The samples are therefore continually checked as they are transported from one dish or tube to another.

To have a better idea, let’s go through how RI Witness works in detail:

Tracking Samples: The first step is to keep track of the samples:

The RFID tags in RI RIS enable embryologists to identify, monitor and record patient samples at each stage of the ART treatment.

The whole lab space can detect wireless signals from RFID tags, ensuring a secure cycle record.

RI Witness reads all dishes at the same time, allowing the operator to operate uninterrupted.

The second phase is carried out during the insemination process.

The presence of a RI witness certifies the identification of the samples, allowing the embryologists to continue with the insemination procedure.

Furthermore, if the samples become unsuitable in the middle of the procedure, the system detects them quickly and pauses the operation, eliminating any possible problems.

Even samples that are not transmitted and are frozen for future use may be identified if necessary.

The third step is taken throughout the transfer process:

During the transfer, the female recipient’s ID card is automatically verified against the embryos right before the transfer.

Is RI Witness compatible with many dishes and tubes for testing?

Yes, RI Witness works with a variety of meals. Regardless of their number, all tubes and dishes are quickly recognized and examined for compatibility.

How does an RFID label transfer data?

RI Witness uses RFID tags and a reader. The reader emits electromagnetic waves, which are picked up by the tag. The RFID tag then pulls power from the reader’s generated field to power the microchip’s circuits. The microchip then modulates the waves sent back to the reader via the tag, and the reader transforms the new waves into digital data.

RFID tags are safe for gametes and embryos.

Because the RFID tags are passive and lack an internal energy source, they are only triggered when they are within 1-5cm of a RI Witness reader. When RI Witness RFID tags are not on a reader or incubator, they do not broadcast or receive radio waves. Embryos and gametes are only exposed to radiofrequency fields for a brief period.

How can RI Witness help the IVF clinic?

RI Witness distinguishes the laboratory from the competition, in terms of quality management or innovative lab technology. The electronic witnessing method also provides patients with more assurance that their samples are secure and will not be mixed up at any stage throughout their treatment.

It also increases lab efficiency by simplifying labor procedures. The lab procedures are carried out at the most convenient time, with a live witness present. It provides a real-time picture of the lab, aids in managing staff training and scheduling, analyses lab data, and simplifies audits.

It is beneficial for embryologists and other lab members to manage cycle data quickly. They may confidently focus on their processes and work with the most incredible support system.

The third step is taken throughout the transfer process:

During the transfer, the female recipient’s ID card is automatically verified against the embryos right before the transfer.
