some reading, page-13

Vintage im pretty sure Oraline's figures are from the same reports in the past. Yet some other devices seem to be more recent studies.

It did point out to further testing in Queensland for roadside testing, as this was the one area all devices struggled with. Results of these tests are obviously yet to be released.

In relation to Oraline im almost certain the results are from the same Rosita 2 study, yet contradicts itself when saying no significant improvements have been made since this Rosita study. So how does one weigh up whether theres been improvement unless they do another study.

Anyway i been out all day in London and just placed it on Hotcopper for people to have a gander at.

Theres 3 or 4 articles on oral fluid testing on that site, for people who have time to research.
