Abstract
We disclose a method of tagging nutritional or drug compositions using chemical entities which are known to be safely consumed and which are detectable using known techniques, including near IR spectroscopy. The chemical entities used as tags may be detected in easily obtainable biological samples, including urine and feces. The biological sample may be deposited into a medical toilet which may analyze the biological sample using an analytical device associated with the medical toilet. The tag may be identified and quantified to then identify and quantify the nutritional or drug composition the subject consumed along with the tag. This system may be used to track the source of a food or drug, confirm compliance to a prescribed diet or drug treatment, confirm drug consumption in clinical trials, identify the source of contaminated food, and identify the food substances used to produce food products.
