ObjectivesDetermine the sensitivity and specificity of a Point-Of-Care test ( COVIDISC) for SARS-COV2. The novelty of the test is to integrate, on the same (low-cost) compact plastic/paper device, solid phase RNA extraction and RT-LAMP amplification, all reagents being freeze-dried on it. MethodRetrospective study with a cohort of 99 patients characterized by real-time RT-PCR. The 37 positive naso-pharyngeal samples cover a broad range of viral loads (from 5 gc /{micro}L to 2 106 gc/ {micro}L of sample). ResultsThe COVIDISC found 36 positives (out of 37 by IP4 RT-PCR protocols) and 63 negatives (out of 62 by RT-PCR). ConclusionThe sensitivity of the COVIDISC, found in this 99-patient retrospective study, is 97% and the specificity 100%.

"Similar papers" are the closest papers from that journal in the model's embedding space. They show what the match is built on, but the ranking comes mostly from a classifier over the whole training set, not from these examples alone.
