Quickly, in terms of individuals, they're not interested in reporting; they're interested in finding out what it means to them.
Going back to the question about reporting positive results, I'd be quite concerned about that. If you're reporting negative results, it indicates that further testing is required. Reporting of positive results becomes anecdotal type of information, and I see potential for great misuse of that anecdotal type of information. I'd approach that extremely cautiously.
