Metabonomics is concerned with the metabolic profiling of people, animals or other organisms in order understand the impact of environmental changes, genetic changes, disease, clinical interventions, dietary changes or exercise.

Pharmacometabonomics is a new branch of metabonomics that is concerned with the prediction of the effects of drugs on a person or animal, based on an analysis of their pre-dose metabolic profile. It is predicted to have much future importance for personalised medicine.
