Yeah, based on the Cochrane paper I’d interpret “one positive result and one negative result” as an overall update towards having COVID. In general, both rapid antigen tests and NAATs are more sensitive than they are specific (more likely to return false negatives than false positives.)
Though also see the “Caveats about infectiousness” section, which suggests that NAATs have a much higher false positive rate for detecting infectiousness than they do for detecting illness. I don’t have numbers for this, unfortunately, so I’m not sure if 1 positive NAAT + 1 negative NAAT is overall an update in favor or away from infectiousness.
