Résumé

Objectives Determine 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. Method Retrospective 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 /µL to 2 10 6 gc/ µL of sample). Results The COVIDISC found 36 positives (out of 37 by IP4 RT-PCR protocols) and 63 negatives (out of 62 by RT-PCR). Conclusion The sensitivity of the COVIDISC, found in this 99-patient retrospective study, is 97% and the specificity 100%.
