News & Views on Systemic Body Odor and Halitosis such as trimethylaminuria TMAU. If you have fecal odors or bowel odors it may be metabolic/systemic

Fart Tracker sensor device

For systemic body odor/halitosis, a handy sensor is very much needed as most sufferers cannot smell their own malodor. Up until recently the technology has possibly not reached a stage to create such a device, but it seems the technology is getting close.

The 'first version' of the Fart Tracker (officially called CH4) may be something of use to the systemic malodor community, as the impression is most suffer from what is known on the forums as 'fecal body odor' ; so the same types of volatiles that cause fecal smells are likely to be of interest to the 'FBO' community.



The Fart Tracker seems to be a new project by a graduate student. It is not yet been produced for the consumer, but it is available to pay for a pre-device on Kickstarter ($120 ?).

I have not been able to see what it actually detects. If it just detects wind movement then it would be of no use for systemic malodors, but if it detects certain volatiles such as sulfides, then in theory it may be of some use.

The main thing is that detectors that may detect sulfides and amines that may make up most of the volatiles that people with what I call 'FMO3 malodors' now seem to be at an early stage but hopefully will be a thing of the future.

My suspicion is that a device for the metabolic malodor community would need to detect volatiles such as :
dimethylsulfide
hydrogen sulfide
thiols
and many more which I do not wish to rule out at this stage

So I guess the 'Fart Tracker' is unlikely to be of use to people with metabolic malodors yet, but it's on the right track.    

Things to keep in mind about this device (for metabolic malodor community) :
It depends what is it sensing (volatiles ?)
How sensitive and specific is it ?
It's a start-up project.

What the metabolic/systemic malodor community needs :
A test to detect all volatiles likely to cause metabolic malodor
A DNA test program, initially to test FMO3 gene
A trustworthy sensor device
A cure or at least therapies

Genos is back with it's EXOME test

Note :
Exome/Genome testing may be better option than single gene testing.

See this post : link

Note : Genos Exome Testing.

Exome testing is almost the same price now as single gene testing. Also Genos is consumer friendly, which standard DNA labs are not.

So the blog offer to test solely for FMO3 is almost obsolete, and so no longer offered.


Does Genos fully sequence FMO3 gene ?

At the moment it is not clear, but hoped this will become clear over the next few months

Note : possible 'wild west' way of testing FMO3
Use an ancestry dna site and rummage through the raw data
