    Snippet: All nasopharyngeal swabs samples from healthy volunteers were submitted to the six considered SARS-CoV-2 assays to check the generation of unspecific response. We observed consistent falsepositive results for N and N2 (60 out of 60 samples for both). N3 assay generated false positive signal or inconclusive results in 13 out of 60 tested samples. N2, N3, and N assays were not considered for subsequent experiments due to the lack of analytical spec.....
