Peres Foodsniffer available to buy now : Any use for systemic malodor volatiles ?

Will you be buying one ?

About : Peres Foodsniffer for consumers (note : you need a smartphone to read the data)

Context : Could it be used to detect volatiles emitted by people with metabolic/systemic malodor problems ? (such as dimethylsulfide ?)

My current view :  I guess it should be able to. It says it can detect 100 or more VOC's and I'm guessing that many 'food waste' volatiles will be the same volatiles emitted in 'FMO3 malodor syndrome'. But this is a guess

Conclusion :
It's $120 in the USA/EU. Consider buying it as a metabolic malodor detector as a total gamble and could be no use to us. But if it works it could act as a 'sniffer' for the metabolic malodor patient who normally cannot smell themselves (self-anosmia)

Peres Foodsniffer can be bought on their website : link
Cost (Feb 2015) : $120 EU/USA : $135 elsewhere

My initial comment :
At this stage in the understanding of metabolic malodors, which are caused by unmetabolized  volatiles circulating in the bloodstream/lymph etc, it is essential for the sufferer to have an electronic device that can detect the malodors (volatiles). Up until now there has seem to have been no device suitable for detecting volatiles in realtime for consumers. Hopefully this is about to change as the technology may finally be ready for this purposre.

I think a few companies are near to marketing such devices. The first I have heard of that's 'consumer-ready' is the Peres Foodsniffer which is due to ship in mid-March.

There are 2 things that are important about a sensor for metabolic malodor detection capabilities :
Sensitivity (how well it detect volatiles, i.e. at what levels)
Specifity (what volatiles it detects)

I have no idea about these 2 factors for the Peres. I couldn't find any data on their website

However I am hopeful it might be useful as a first generation step to a metabolic maldoor sensor device but I may be wrong

Final comment for the metabolic malodor community :
Might be worth buying (as a pioneer) but buy it thinking of it as money possibly written-off.

Update Aug 17 :
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
