The alphanumeric code or kit code needed for registration can be found on the tubes that preserve the saliva and on the instruction leaflet included in the kit.
It is important to keep the instructions so as not to lose the kit code, as well as to create an account and register the kit before sending the sample to the laboratory.
Once the account is created, you will be able to check your kit code in the upper right part of the screen in your private area.
