Hi - I'm not in Australia, but am across "The Ditch" in New Zealand. I went to a doctor and gave them info on TMAU as I've had a distinctive fish odour pretty much since I reached puberty. She ordered a trimethylamine urine test and I presume the sample must have been sent to the only lab in NZ that tests for it, in the South Island. It took about 8 weeks to get my results back and they were negative, so I'm really bummed about that and not sure what to do next. It's such an incredibly frustrating condition.
