Please note from 13 Feb 2017 new reference ranges and tests reported for TMA profile. TMA/TMA-n-oxide result has been replaced by % N-oxidation.  Dimethylamine is no longer routinely analysed as part of the TMA profile - if it is required it should be requested separately.

 

PLEASE NOTE FROM JANUARY 2018 TOTAL TMA/CREATININE RATIO WILL NO LONGER BE REPORTED.  The parameter is not directly required for diagnosis and is an assessment of the amount of dietary choline going through the pathway, which aids in the interpretation of results.  The parameter will still be measured but not reported, rather a comment will be added if the value is low indicating insufficient stressing of the pathway which could lead to a false negative.
