As testing for COVID-19 has become commonplace so have questions of tests accuracy. False-positive tests have generally attracted more attention than false-negative tests but both are important in successful management of local disease epidemics. The increasing number of at-home testing kits for COVID-19 makes it convenient to test for COVID-19 plus considerably safer than risking exposure by going for testing at a public location.

Widespread testing of asymptomatic people known as screening or surveillance testing leads to high numbers of false positives even with accurate tests. However because they are less accurate than PCR tests the results need.
This means that it works by detecting genetic material from SARS-CoV-2 the virus that causes COVID-19. These tests have false positive rates of around 2 which means that if you keep using them youll eventually test positive even though you. False positives and negatives are common in medicine which for all the efforts of doctors and pathologists can never be 100 percent accurate all the time.
