RI Witness: The Highest Level of Security and Safety for Our Patients and Embryos Alike

Our laboratory at Medfem Fertility Clinic maintains an efficient and trusted system of patient sample identification, using multiple identifiers on sample labels with double witnessing of each critical step of treatment. To attain an even higher level of care, Medfem has now installed RI Witness, the most secure system available for IVF laboratories.

RI Witness uses Radiofrequency Identification technology (RFID) to monitor critical laboratory procedures, creating a complete record of each stage of a patient’s IVF cycle. The system tracks and records all activity and locks the patient’s identity to the sperm, eggs, and embryos at every stage of the treatment.  If a patient’s sample comes into proximity with those of other patients, the embryologist is alerted, and chart locked until the oversight is corrected.  RI Witness provides our staff and patients with the peace of mind that the most secure and best possible procedures are being employed to prevent any laboratory errors.


RI Witness works from the start of the IVF treatment when the patient is assigned an RI Witness ID card that has their identity assigned to it, to the freezing of sperm, eggs and embryos and finally to embryo transfer.

The RI Witness system also logs the time, date, person completing the procedure and the person double witnessing at the start and end of the cycle. These records are kept in each patient´s notes. The system is completely safe. Extensive tests have been carried out to ensure that there is no danger to any of the samples placed onto the witnessing system.

Medfem is the first infertility clinic in Africa to have installed RI Witness.
