Mark, if you're asking the person whose profile is Lytz-26 to add his/her DNA test, I'm afraid it's not going to work.
That person is living. Because of WikiTree's privacy protections, living persons who are not WikiTree members are assigned "unlisted" privacy level, which means that only members on the trusted list can see anything about the person. Everyone else can only see the last name and the decade of the person's birth.
Another restriction to protect privacy is that DNA test results for a living person can only be added to WikiTree by that person. So Lytz-26 would have to join WikiTree and add his/her test result, after which he/she could make you his/her profile manager and not have to ever do anything else here if he/she doesn't want to.
