This online form is the first step to requesting your zygosity results. Because sharing zygosity results means we are also sharing information about your twin with you and vise versa, we must ask you to complete a formal consent form. Both you and your twin must complete the consent to release zygosity results; otherwise, we cannot release the results to either twin.

The information on this form is collected using a survey application, called REDCap (REDCap Info), which has been developed for collecting information confidentially. Please complete this online form and click the "Submit" button at the end to request your zygosity consent documents. You can also request your zygosity consent form by email ( or by calling our toll-free number (1-800-URA-TWIN) and leaving us a message.

Thank you!
