How the Lucira Test Kit works
Set up the test kit.
The kit arrives with a test device, sample vial, swab, batteries and simple instructions. Insert the enclosed AA batteries in the device and place the sample vial in the test unit to set up the test.
Collect a sample.
Open the test swab packet and rotate the swab in each nostril five times. Then stir the swab in the liquid in the sample vial, and seal and press the vial down in the test unit.
Wait 30 minutes for results.
The “ready” light will blink until a “positive” or “negative” green light is illuminated within 30 minutes.

Molecular vs. Antigen Tests
Molecular tests, including PCR tests completed in a lab and the PCR-quality Lucira Home Test Kits, detect the genetic material of the virus that causes COVID-19, while antigen tests detect proteins on the surface of the virus. Molecular tests have high accuracy for both symptomatic and asymptomatic people. With antigen tests a positive result is usually highly accurate but a negative result may have missed an infection, especially in the presymptomatic phase.
