Measurement of urine for the ratio of trimethylamine to trimethylamine oxide is the standard screening test. A blood test is available to provide genetic analysis. The prominent enzyme responsible for TMA N-oxygenation is coded by the FMO3 gene. False positives can occur in the following conditions, where elevated TMA can be present in the urine without any underlying<unk> : * Urinary tract infection * Bacterial vaginosis * Cervical cancer * Advanced liver or kidney disease A similar foul-smelling odor of the urine has also been associated with colonization of the urinary tract with a bacterium called Aerococcus urinae, especially in children.
