That sort of issue crops up all the time in medicine. Screening for conditions will always produce some false positives, and the ramifications can vary from scaring the shit out of someone for a few weeks before you determine they don't have cancer after all to them dying as a result of further testing/treatment that wouldn't have happened without that initial screening. That and the potential adverse outcomes of the screening itself (and its costs) always has to be weighed against the value of the true positives.
