Yes. If your healthcare provider shared your email address with us, then you should have received an email invitation, which contains a special link to register your additional test(s).
Alternatively, when you are logged into your patient portal account, click “Register a Test” in the menu at the top of the screen. This will take you to a page where you will be prompted to enter the confirmation code from your patient card and your date of birth. If you don’t have the patient card, but you know your requisition number, this can also be used as your confirmation code.
