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."

MeBO-Biolab gut dysbiosis study : Tester 11 results

Tester 11
Male, early 30's
Odor problem:
Body odor and halitosis problem. Smells include body odor, fish, sometimes garbage. Had problem for around 15 years. Negative TMAU urine test. Cannot make a connection between diet and smelling, but does with sexual activity
Gut problems
Other problems
No obvious problem
TrimethylaminuriaNegative urine test

Results :
Tester 11
Gut FermentationEthanol normal.
Raised for 2,3 butylene glycol
Tester comments it shows probable BACTERIAL dysbiosis
Gut permeabilityRaised between 242 and 550 (leaky gut)
body odor gut permeability test 11

D-lactate503 (normal is below 60)
Vitamin B2
1.11 (normal is below 1.20)

Tester 11 results are back and this is an interesting case both in what he feels provokes the symptoms, and also the pattern of the results themselves. The tester, a male in his early 30's who had had the problem for around 15 years, cannot make a connection between diet and odor occurrences, but makes a certain connection with sexual activity. There are too many speculative reasons why this would be, including possibly something to do with hormones and other chemicals released in the bloodstream.

As for the results, the tester was fine for ethanol (implying yeast gut infection) which has been quite a common trend in our study. Instead his gut fermentation test came back as 'probably bacterial dysbiosis'. This seems to be mainly due to the 2,3 butylene glycol result. This is the first 'bacterial dysbiosis' gut fermentation result we have had, although others have had alcohols higher than normal but the lab did not seem to think them significant enough.

The indicans test is positive, which is generally thought to imply an overgrowth of putrefactive bacteria, and the d-lactate was extremely high. D-lactate is regarded as being produced by lactic-acid producing bacteria from carbohydrate fermentation. This is only the 2nd person to have a high d-lactate result. We were planning on discontinuing this test, but will keep it as an option now.

Gut permeability was also increased (meaning 'leaky gut'); the 7th of our testers that has raised permeability at some stage in the graph.

B2 was normal. Only 4 other people have tested for B2, with 3 being deficient. 2 of them also had raised ethanol.

Overall, this testers results do seem to indicate a bacteria overgrowth issue in the gut of some kind, but not a yeast issue.

About the MeBO-Biolab gut dysbiosis study

The MeBO-Biolab gut dysbiosis study is a sufferer-led project under the guidance and supervision of Dr. Irene Gabashvili, started by MeBO Research with the help of Biolab Medical Unit in London to use a number of tests from Biolab that specifically test for biomarkers of gut dysbiosis, including yeast overgrowth, certain bacteria overgrowth, and 'leaky gut'. Each volunteer needs to pay for their own tests. The criteria for the tests were total cost, and the tests on offer. Although the study is intended as an example of what health-problem communities could achieve with the internet nowadays; it also hopeful the tests in themselves will be useful, although no direct co-relation can be made with the results and your odor problem. To be included in the study, please fill in the survey and you will be contacted by email.
