I am excited by this technology. For early stage, it appears robust, and the numbers are very encouraging.
I have a concern that if there is a weakness, it may manifest in late stage cases. Conventional wisdom is that Bb tends to flee fluids like blood (or urine?), and has a tropism for tissue. Hopefully tests like this will belie or overcome that. Or, it may act similar to a PCR, in that, if you register a positive, it will be hard to dispute; but having a negative, for late stage cases, might prove little definitively. What are they quoting? 88%? Still very impressive.
