Denver TMAU Test Lab survey click here
click to Read more/less

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."

Graph of TMAU results from Sheffield 1997-2012

Sheffield TMAU results : 1997 - 2012
Graph of TMAU urine test results tested at Sheffield Children's Hospital 1997-2012

Kindly given to MEBO Research by the tester ; Nigel Manning : Principal Clinical Scientist, Dept of Clinical Chemistry, Sheffield Children's Hospital, Sheffield.

Nigel Manning has kindly given MEBO Research a graph of all the TMAU biochemical test results done by his lab at Sheffield Children's Hospital since his lab started testing in 1997 up until the end of the 2012. This is an updated graph of one given to MEBO Research in a previous year.

Sheffield Children's Hospital TMAU urine test reference range :
The lab tests the trimethylamine and trimethylamine oxide levels in urine samples. The reference ranges used by the lab are (for a normal person):
That the TMA level should be lower than 11 umols/mmol creatinine
That the TMA/TMAO ratio should be lower than 0.21 (this as a % works out at >79% TMAO)

So from the graph it can be seen that those in the small square in the bottom left are 'normal'. Those above the horizontal red line have TMAU2 (too much trimethylamine), and those to the right of the vertical red line have genetic TMAU (TMA/TMAO ratio too high). In total, 1731 samples have been tested in the graph.
