A growing concern: inability to diagnose vulvovaginal infections correctly.

The accurate diagnosis of vulvovaginitis should distinguish obstetrician-gynecologists from the vast majority of primary care physicians. Diagnostic accuracy is lost when physicians are unable to do a microscopic examination of vaginal secretions, as well as a "whiff" test and a pH determination. Structured instruction in the use of a microscope should be a required component of obstetrics and gynecology residency training. Physician compensation for this testing should be commensurate with the time and office expense required to provide this service.
