Lab-based molecular tests are the most accurate way to determine whether you have an active coronavirus infection. Several companies now offer at-home molecular tests, where you mail your own sample in for analysis. Antibody tests are notoriously unreliable. And even if you get an accurate antibody test, that won’t tell you for sure if you’re immune to the coronavirus. With few exceptions, the Infectious Disease Society of America does not recommend antibody tests for individuals, owing to low accuracy rates.
