In comparison, a correctly done PCR test can return lab-approved results with 98% accuracy, according to the same study based on pre-Omicron data. Luckily, tireless research in the field has produced some promising results, including some vitamins and minerals that can potentially help prevent cases from becoming severe. "False positive results will happen in a fraction of a per cent of occasions, but false negatives (a negative result when in fact you do have Covid-19) are more common.

In theory a Neti pot or saline spray could do that, but it is unlikely. The likelihood of a false-negative result depends on both the timing of sample collection and the type of specimen collected (in the case of the molecular test). Different assays use antigens from different parts of SARS-CoV-2, and some combine IgM and IgG, and so different levels of cross-reactivity with other coronavirus antibodies are possible.
