Urine Trimethylamine And TMAO Test

Hawaii rates for HCPCS 0256U

Measures two related chemicals in urine — trimethylamine and its oxidized form, trimethylamine N-oxide — and reports them together as a paired profile. Trimethylamine is produced when gut bacteria break down certain foods, and the body normally converts it into trimethylamine N-oxide.
