fulcrumgavel...did you read more than the abstract because the test you cite is not that accurate in sensitivity or specificity as it seems?
The study you cite is a very nice paper published in 2009, from a french group. This was a large study in which over 900 patients were enrolled. The test did show a very high degree of specificity and sensitivity, for a certain portion of the tests. If you read more than the abstract, you would have seen that the real data is actually very different. Out of 968 patients enrolled, more than 10% were "not available." this was due to things like mucous being present (which is present in a lot of these samples), or user error. So what the authors did, was to omit these results from analysis.

UTHSC Houston chose to include samples which did not give exactly what they wanted, for the purpose of being candid and accurate. (They were under the impression that users would presumably want to know how the test truly performs, ie, it's accuracy, as well as its sensitivity and specificity.)

I believe the accuracy/credibility of the study you cite is in question.
