RI Witness™ is a traceability and control system for all biological samples used in the IVF laboratory. It operates through wireless receptors installed within the work cabinets, which automatically verify the identity of all samples, whether they are sperm, oocytes, or embryos. The materials containing the samples are previously labeled with a unique microchip for each patient. This system helps prevent possible errors and ensures the traceability of gametes and embryos.
