• Tests should be dated within 3 days of the first conference event you plan to attend. For example, if the first event you plan to attend is the opening session on Sunday, then your test should be dated Thursday or later.
• PCR or rapid antigen test is acceptable.
• Test must be administered by a clinician (no self-administered/over the counter tests will be accepted).
• Each attendee must have a unique email address. If you are bringing a guest, the guest must be registered for the conference and they must submit their results separately using a different email address.
• Please do not attempt to submit a result more than 3 days in advance. Your result will be rejected and you may be unable to resubmit via the portal. You will have to contact Vital Circle directly.
• If your result is rejected, you will receive an email with the reasons and you will need to work directly with Vital Circle on a resolution. ACC staff will not have access to your submission or the reason for the rejection. The only details that ACC staff will have is whether or not you have been cleared to attend the conference.
