Is there a diagnostic test, for example, genetic testing, that will let one know if they are gay, lesbian, transsexual or heterosexual?

No. there is no genetic test that can be administered to tell anyone what their sexuality is. That can only be done by honest self examination. Transsexualism, which has nothing to do with sexual preference, is different. We can't do a genetic test, but we can administer cross-sex hormones and see if the individual responds positively or negatively to them. That procedure is routinely done after the individual has had an extensive period of psychotherapy and is fully aware of the consequences. A negative reaction would result in extreme anxiety and discomfort. A positive reaction is one where the individual reports a calming affect. Often described as a feeling of well-being.
