Has anyone had any success accessing tests not approved for clinical diagnosis in the US? If so, what was your approach? As an example, consider the Virochip assay. The UCSF Viral Diagnostics and Discovery Center website states the following: Note that the UCSF Viral Diagnostics and Discovery Center is a research laboratory and cannot perform individual patient testing due to federal regulations. We are unable to perform clinical diagnostic testing, and only recommend that patients see their personal physician to discuss available clinical test options. Yet, there must be exceptions. For example, Joe DeRisi in his TED talk, "Solving medical mysteries", discusses how his group diagnosed a patient with Parainfluenza-4 when the hospital couldn't figure out what was wrong after a bunch of testing. The Virochip assay was used for this case and as stated above, it is not approved for clinical diagnosis.
