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."

The Road to Ammonia

by Dr. Irene Gabashvili,
Scientific Director
MEBO Research


Why do I smell like Ammonia? This question, in thousands of variations, has been asked over and over again at every major question/answer site, especially teen, bodybuilding and athletic forums.

The Internet provides plenty of opinions.

Medical sites talk about diseases like chronic kidney failure, hepatic cirrhosis or H. pylori infection. Fitness sites recommend drinking more water, reevaluating protein sources and eating more carbohydrates.

What are these diet-odor links? And what's the Science? Ammonia may be formed during the alkaline hydrolysis and deamidation of proteins - by our own metabolism and the metabolism of microbes that call us home. If our kidneys can't handle the load of nitrogen, it's excreted as ammonia in sweat. Excretion increases 10 times as temperature goes from 70 to 100 Fahrenheit.
Preliminary correlations in the Aurametrix knowledge base show exactly what's expected: excess protein does lead to ammonia-like odor...Aurametrix, however, recognized that all these odors described by the user may be related to nitrogen-containing compounds.


Aurametrix is a breakthrough analysis tool that correlates users' actions and reactions based on what information they enter into the system. Preliminary correlations in the Aurametrix knowledge base show exactly what's expected: excess protein does lead to ammonia-like odor.

But wait a minute - does it say the same about excess fat?

An example provided by one of our users is very interesting. The user logged a few foods he thought were contributing to odor. These were different odors according to the user - ranging from "Ammonia-like" to "Fishy", sharp, cloying and stale. Aurametrix, however, recognized that all these odors described by the user may be related to nitrogen-containing compounds. When these three data points were analyzed along with four foods that the user did not associate with any odors, Aurametrix displayed only one result:




Based on your Aura entries, the following may be contributing to "Ammoniacal odor" in a 3 hour timeframe:

  • Hexadecanoic acid (when consumed more than 0.7 grams, up to 1.19)




Hexadecanoic acid - commonly known as Palmitic acid - is one of the most common saturated fatty acids in the Western diet. Palm oil and coconut oil contain especially high levels of this acid. What effect does this acid have on metabolism? It down-regulates glycose metabolism and protein metabolism, affecting Calcium or mRNA binding proteins [1]. So there may very well be a connection!
