Tissue Registry - Signing Up/Removing ← Knowledge Base How can I sign up? I do not want to sign up online. Is there another way for me to register? May I later withdraw or revoke my consent to be listed on the Organ and Tissue Donor Registry? May I later change my mind and withdraw my refusal to make a gift? How can I refuse to make an anatomical gift and bar others from doing so on my behalf? Can I take my name out of the Registry if I change my mind? How can I remove my name from the Registry?
