Tests (PCR vs. Antibody)
Sensitivity and specificity can be easy to mix up. In the most general terms, sensitivity is finding a positive test in a person that really is sick. Specificity is finding a negative result in someone who is not infected. A good test will do both. No test is perfect, but a RT-PCR/molecular test is considered to be more accurate than a rapid antigen test.
Antibody tests check if you have been exposed to Covid in the past, so they don’t necessarily tell you if you are currently infected.
