The test that is right for you will depend on why you are taking the test and how soon you need to get results. While antigen tests deliver results in about 15 minutes, before the omicron variant emerged they were only 58% accurate for people who didn't have symptoms, or 72% accurate for those who did. The first test created to detect covid—and still the most widely used—is a molecular test called pcr (polymerase chain reaction), says sheldon campbell, md, phd, a yale medicine pathologist and microbiologist.

The performance results fall below the world health organization recommendation of 80% sensitivity and question using at in general population, especially when asymptomatic.

While you may not feel symptomatic when you take a rapid test, your immune system could be hard at work keeping symptoms from developing. This includes a minimum clinical sensitivity of at least 80% (for specimens collected within 7 days of symptom onset) and a minimum clinical specificity of at least 98%. In part one of the study, with the primary objective to.

Under those conditions, a rapid test produces correct results 80 to 90 per cent.

Pcr tests are generally considered more accurate than rapid tests, but rapid tests have benefits that pcr tests do not have—for example, they provide results faster and for a lower cost. Although they are not as good at detecting virus as a nucleic acid test. Rapid tests generally are not as accurate when you have no symptoms, but they.
