Your sample will not be processed until registration is completed. When your unregistered sample is received at the lab, an email titled "Action Required" will be sent to the email address provided when the order was placed. This email will contain your sample's barcode (see example below), which you can use to register online.
Keep in mind that if you received your kit as a gift, the purchaser will receive this email if their email address was provided when placing the order. You may need to contact them directly for your kit’s barcode.
