Genetic testing is available to distinguish between primary genetic trimethylaminuria, which will result in severe symptoms, and secondary, non-genetic forms of the disorder. In mild cases, symptoms are relieved when foods containing choline and lecithin are restricted. The samples are analyzed to determine the amounts of TMA and trimethylamine N-oxide (TMAO) that are present to determine if the enzyme FMO3 is working properly.
