Denver TMAU Test Lab survey click here

USA survey for anyone who wants to improve Denver TMAU test

begun : Dec22
end : no ending for now

A trainee genetic counselor is working at the Denver TMAU test lab. Probably as part of her training. As a project she wishes feedback on any aspect of the Denver TMAU test and process. You can fill in the survey and/or email her (email address is in survey). It's meant for USA people, but perhaps others can give their view too (as we have so few opportunities).

quote from her rareconnect post

"Hello all! I wanted to make you aware of a research study being conducted to better understand the experience and needs of individuals with trimethylaminuria with a goal of being able to create improved patient and healthcare provider education materials. Any participation is completely voluntary and all responses remain confidential. Feel free to use the contact information within the link with any questions or share the survey with others with TMAU."

Differences between Trimethylaminuria urine testing at Arkansas CH and UC Denver

Arkansas Children's Hospital
is no longer performing the test for TMA, as per the
Supervisor, Clinical La/Metabolic Genetics, AKC
September 2013

Currently the only known Trimethylaminuria urine testing labs in the USA are :
Arkansas Children's Hospital, Metabolic Genetics Laboratory
University of Colorado Denver, Biochemical Genetics Lab
At this stage in the evolution of TMAU testing, there seems to be no agreed standard, and each testing lab sets their own testing procedures and reference range. This post attempts to clarify the differences between the 2 labs known to be TMAU testing in the USA.

The main differences seem to be :

Arkansas only tests for Trimethylamine levels, and is much cheaper (around $130)
Denver tests for trimethylamine and trimethylamine-oxide, but is dearer (around $250)

Since TMA-oxide is the final metabolized product of normal FMO3 function, it would seem best to test for TMA-oxide as well as a defining test. TMA-oxide gives you an idea of how well your FMO3 enzyme dealt with the TMA load, and therefore gives an indication as to the % function of the enzyme. It is not possible to get an idea if you have a genetically poor functioning FMO3 enzyme without testing TMA-oxide levels.

Apparently, The 2 labs also use different equipment for the TMAU urine test, although probably both are reliable.

Probably a best idea would be to use the Denver lab as a first choice, and perhaps use the Arkansas lab for monitoring TMA levels if price is a factor.
