There are no scientific studies investigating this possibility. This, there is current;y no objective evidence to suggest that being in ketosis, whether via the ketogenic diet nor exogenous ketone supplements, could cause a “false positive” on a drug test. This question has been posed often in online forums by users consuming a ketogenic diet and concerned by such a possibility. Collectively, the responses to these questions include anecdotal reports of users who were in ketosis when drug tested and experience no such problems. This, it does not appear to be a matter of concern.
