Antigen testing only takes 15 to 30 minutes to know if a person is a COVID-19 positive. Such is way faster than what molecular testing can do. It is also less expensive than RT-PCR testing that requires specialized laboratory techniques. Antigen test is effective in detecting COVID among high-congregate environments and high-risk groups.

Available antigen test kits have 80 percent sensitivity and 97 percent specificity. Those factors granted them emergency use authorization (EUA) from the World Health Organization (WHO).


Contrary to its advantages, antigen testing requires people to travel and go to testing areas, like hospitals, clinics, or pharmacies. Such increases their chances of getting infected along the way.

As reported by the US Food and Drug Administration (FDA), there are potential false positives issues. In a Cochrane systematic review of 22 antigen tests, the study found an average of 56.2 percent sensitivity. When samples do not have sufficient viral protein, the result will most likely fall to false negative as it cannot yield a positive test.

Antigen test is less sensitive and less accurate than molecular tests, proving their ineffectiveness in providing accurate interpretations. Thus, you must undergo a confirmatory RT-PCR test if your antigen testing tested negative.
