Re: Australian people - have any of you been tested?

One problem with TMAU testing is that so few labs test for it that they each set their own reference range. This means one lab can say % of TMA oxidized is <85% is 'positive', whereas another will say <80%, and another <90%.

Some don't even test for TMAO and just have a TMA cut off point. Again this varies lab to lab.

I would say whichever lab is the most 'liberal' (i.e. their % is around <90% or more for TMAO%) is most likely to be closest to accurate. I think most labs are still too conservative (that seems to be the way medical thinking works) Tweet
