Witness System
Traceability and control
The Witness systmen is a tool used in Vida Fertility’s assisted reproduction laboratories that allows traceability and control of all the biological material of each patient (eggs, sperm and embryos).
The implementation of this objective and safe system allows us to prevent the possible confusion that may occur during the manipulation of them.
Who is for?
All our patients benefit from this system, since it is used whenever a sample arrives to our laboratories to detect and control all activities we perform.
At Vida Fertility we are comitted to safety and to transmitting confidence to our patients, the Witness system helps us to have all the necessary transparency.
How is the Witness system process?
The system allows gamete and embryo samples to be monitored and identified by radio frequency. All work areas in the laboratory and the clinic rooms where these sample may go through are equiped with radiofrequency readers.
At the beginning of the treatment, each patient is provided with an identification card. This will be the starting point of all processes. This card will be introduced into the readers and used to progress to the next stages. In addition, every time a sample comes into contact with a laboratory work area, the wireless receivers will automatically check its identity. This way, we know exactly who, when, how and where these biological samples were handled.
Safety and control in embryo transfers
In the event of an error in the allocation of gametes, the Witness System emits an acoustic signal alerting us of a miss-matching that paralyses the process until it is resolved.
For example, for her egg retrieval and then her embryo transfer, the patient would introduce her identification card in the reader located in the operating room, avoiding any doubt or mistake in the lab before the procedures.
FAQs about the Witness System
The Witness System is a radiofrequency identification (RFID) technology that ensures each sample of eggs, sperm or embryos is perfectly identified and exclusively linked to the correct patient at every stage of treatment.
At Vida Fertility, we use this system throughout the entire IVF process to eliminate any risk of human error during sample handling and to guarantee the highest levels of traceability and safety.
Yes. At Vida Fertility, we adhere to the highest safety standards. Thanks to the Witness System, every test tube, dish or container carries a unique chip electronically linked to your identity.
Before any procedure — fertilisation, culture, vitrification or embryo transfer — the system checks that the samples match your profile, blocking any action if there’s a mismatch.
This gives you the peace of mind that your samples are 100% controlled, traceable and secure.
Traceability in a fertility lab means being able to follow and record every step taken with biological samples (eggs, sperm, and embryos).
It includes who handled them, when, under what conditions, and using which techniques. This level of oversight is essential for treatment safety, quality, and reliability — and allows any issues to be identified and decisions made based on concrete data.
The security of the Witness System lies in its automated operation, leaving no room for human error. RFID chips and sensors are installed in key laboratory areas to ensure each step is validated before proceeding, so embryologists only ever work with the correct samples.
At Vida Fertility, we complement this with dual manual checks, internal review protocols, and continuous quality control — guaranteeing complete, transparent traceability.
Laboratories Fully Equipped with Witness Systems
“In the lab, there’s no room for error. Every cell, every embryo, every step must be 100% under control.”
I ’m Beatriz Lozano, Laboratory Director at Vida Fertility, and one of our top priorities is the safety of your samples. That’s why we use the Witness System in all of our procedures — a radiofrequency traceability technology that guarantees every sample is correctly identified, tracked, and protected from the very first moment.
Thanks to this system, you can begin your treatment with the reassurance that everything we do in the lab is designed to protect what matters most: your trust and your future pregnancy.
Experiences of our patients
It is incredible how, from absolute resignation, these doctors have lifted my spirits. They got me pregnant and gave me my life back. They live up to their name.
I had to find a way to become a mother if I wanted to pursue my career and not settle for just any partner. I made the right choice.
From the very first moment I felt I was being listened to, understood, and above all, I felt that my treatment was finally going in the right direction.
Hello dear Mrs Ortega,
you and the whole team of Vida fertility make us so happy. Finally a relief that we can be helped! Many thanks to you and all the others for the great care and exceptional quality work. This high quality means a lot to us. We hope that in 2024 we can take a healthy baby full of love into our arms.❤️
Thanks to Dr. Kathi’s support and by following all her advice, the best moment of the treatment came: I got pregnant.
I didn’t know if I would ever be able to get pregnant and now I’m in my 5th month of pregnancy.
It hasn’t been an easy journey. After the second attempt, I am happy to say that in two months I will be meeting my little girl.
Being able to experience this shared motherhood has been a gift for the two of us.
THANK YOU to this great team for everything!
We highly recommend Vida Fertility to anyone who has already given up hope and wants to give it one last try.
A huge thank you to the entire Vida Fertility team, especially to Sophie and Dr. Spies, who helped us achieve the wonderful project of expanding our family. We met a very competent team who perfectly guided and advised us on the medical choices to make at each stage of our journey. 🫶
I recommend Vida Fertility for their professionalism, humanism, and availability.
Our wonderful baby is the proof that the results are there!
Thank you!
Thanks to Vida fertility, we are now mums. Mums!!
It’s the greatest gift of all, we’re so happy!
The good feeling will certainly have contributed to the success of the treatment.
When we first contacted the clinic, I didn’t expect to become a mum so quickly, and now I even have hope that we might be able to create a sibling for our son with the remaining blastocysts.
Thank you!
I chose Vida Fertility because it’s a clinic that offers human support from the very beginning. I’m convinced that my state of mind, so influenced by the unconditional support they gave me, was key to the success of my treatment.
At the first consultation, I felt heard, understood, and full of hope again. The final transfer, our last chance, took place in February 2024… and it worked. Our little girl has brought immense joy to our whole family.
Being a single parent brings challenges, but I’d recommend anyone thinking about it to go for it. Vida Fertility made my dream come true with my first IVF.
