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."

Human olfactory psychophysics

This is a mainstream research paper about the sense of smell and is probably the current viewpoint of the mainstream on the olfactory system. It mentions concepts such as 'specific anosmia', 'threshold', and 'adaptation'. 'Specific anosmia' is the genetic inability to smell specific smells. Fecal body odor sufferers (or other bowel smells or other odd smells) often say they cannot smell themselves. This also seems to be the general rule for people with external body odor. However, those with fecal body odor can smell feces odor from other sources (not through human skin, it seems), so specific anosmia doesn't seem to be the reason. The same seems true for trimethylaminuria and probably other metabolic body odors, although Dr John Cashman believes that perhaps 8% cannot smell trimethylamine, although it's not known if he means only from humans or from any source. for example, most people seem to be able to smell fish. Another theory for this is 'adaptation' and desensitivity to the smell. This seems more likely than specific anosmia, however, perhaps sufferers have been in situations where a group of strangers complain of a smell but one stranger says they can't smell anything (for instance in school). Adaptation and desensitivity do not seem to account for this. At the moment it is a mystery. the most likely guess is that there is some genetic aspect, as of yet unknown.

That aside, the article is seemingly the 'latest' (2004) in olfactory perception and worth a read
