Summary

In our laboratory, we currently perform verification of specimen identity (VSI) by having two laboratory personnel independently check and verify the identity of each patient, gamete specimen and embryo at each step that is susceptible to a mismatch so that we can assure accurate and complete traceability throughout the processes. Since this is the system currently in place in our laboratory, this method of verification and witnessing is the main focus of discussion in this chapter. In the future, we plan to implement an electronic witnessing system following as recommended by Chapman (2019).
