These tests are not as accurate as the Donald Trump miss Me yet shirtgold standard of PCR but come relatively close. This test looks for viral genetic material. PCR testing is slower (24 hours at a minimum), more expensive, and very accurate (if it is a good sample). The Lucira kit also detects genetic material, but instead of PCR, it uses a different amplification process called LAMP. LAMP is faster but slightly less accurate. Both Ellume and BinaxNOW are antigen or rapid tests, detecting a protein piece of the virus. Antigen tests are also faster but less accurate than PCR tests.
