Yes I did get tested for TMAU and it came back negative. I ate a lot of foods the days leading up to the test that should have set it off so Im convinced I dont have TMAU.
The transport conditions varied a bit between what the specialist said I should do with the urine and what the lab says about how they transport it. But I have been tested before a couple of years ago too and it came back negative as well.
I am about to post a new topic in a moment about how Im going with the faecal body odour and some suggestions if you wanted to check that out :)
