Functional pathology testing is a method of specialty investigation that may be used in conjunction with other naturopathic diagnostic techniques to assist in gathering information to make informed clinical diagnoses. Unlike routine pathology tests, functional pathology testing may provide a detailed assessment of an individual's biochemical, hormonal, nutritional and metabolic status.

These methods are generally employed by naturopathic clinicians for early detection and intervention of potential underlying pathological processes otherwise not identified via previous medical investigations. Functional pathology testing can also be useful in determining baseline measures, so that the efficacy of treatment interventions, such as dietary, nutritional and herbal medicine, may be assessed.
