The detection method—such as antigen detection or molecular amplification—determines the sensitivity and specificity of the test. Antigen tests are prized for speed and simplicity, ideal for at-home use, while molecular (PCR) methods are more sensitive but require lab analysis. The iHealth Covid 19 Antigen Rapid Test and FlowFlex Covid At-Home Test both use antigen detection, providing reliable and quick results for everyday situations. With both antigen and molecular options available, you can choose the right balance of speed and accuracy for your circumstances.
