So getting the values would give you some information. If your HSV1 is high and HSV2 is in that equivocal range there's a good chance it's a false positive.

Results are for the identification of SARS-CoV-2 nucleocapsid protein antigen. Antigen is generally detectable in anterior nasal (nares) swabs during the acute phase of infection.
