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."

The correlation of organoleptic and instrumental halitosis measurements

The correlation of organoleptic and instrumental halitosis measurements

This is a recent paper published on pubmed where the German-based investigators were comparing the ability of 3 halitosis measuring devices against that of someone smelling the patients' breath. They compared the halimeter, which has been mentioned on the blog before; the 'French Kiss', which is probably a cheap device by Tanita intended for the consumer market; and the 'halitox' test, which seems to be obsolete but was a way of checking saliva for sulfides or amines.

Not surprisingly, the outcome is that the halimeter is the most accurate of the 3 devices, given that it is a clinical device. Nowadays many dentists with an interest in resolving halitosis prefer the oralchroma.

The correlation of organoleptic and instrumental halitosis measurements.

Numerous detection systems are available for measuring halitosis. In order to examine their agreement, a study was conducted comparing four selected measuring methods in 100 subjects (52 females, 48 males; mean age: 25 years). Organoleptic halitosis measurement was carried out by an odor judge, and compared with instrumental halitosis measurement by sulfide monitoring using Halimeter, Fresh Kiss, and Halitox (halitosis linked toxin detection assay), with which both VSC (volatile sulphur compounds) and polyamines can be detected. The results show that the values recorded by the Halimeter correlated best with the organoleptic assessment and the least with the results of Fresh Kiss.
