While the FDA issued the first emergency use authorization (aka, not fully approved) for at-home COVID-19 sample-collecting kits in April, the agency has now approved emergency use of a rapid COVID-19 test done entirely at home — no need to mail your tests out to a lab. The Lucira COVID-19 All-In-One Test Kit consists of a nasal swab and is described as "a molecular (real-time loop mediated amplification reaction)" test by the FDA. It's approved for people 14 years and older who are suspected to have the virus and requires a prescription from a doctor. Results show up in 30 minutes or less.
Here's how it works: you swab your nose (as you do in other nasal COVID-19 tests), stir the swab into the provided vial, then place it in the battery-powered testing unit which provides results using a display that lights up either positive or negative. After the test is completed, put it and all of the materials in a plastic bag to throw away.
The FDA says to report your results to your doctor. If the results are positive, the agency advises self-isolation and encourages you to seek additional care. As for those who test negative but still experience symptoms, you should follow up with your doctor.
According to The New York Times, the loop-mediated isothermal amplification reaction (LAMP) of the test detects COVID-19 by repeatedly copying the genetic material found in the virus. LAMP is reportedly faster than a similar lab technique used for many nasal swab COVID-19 tests called polymerase chain reaction (PCR), but LAMP is said to be less accurate (PCR tests are generally accurate).
The Lucira Health website notes that, compared with an FDA-authorized test (that The New York Times reports was a PCR test), the Lucira test was able to accurately detect 94.1 percent of the infections. Note: the test has not been evaluated in people who are asymptomatic.
This at-home COVID-19 test is also allowed to be used in healthcare settings, and the FDA says that it must be administered by a healthcare provider when children younger than 14 are being tested. According to the test's website, it will cost up to $50.
It's important to note that this doesn't mean you can call your doctor ASAP for a test. A press release states that Lucira's test will be available to patients in two places initially: Sutter Health in Northern California and Cleveland Clinic Florida in the Miami metropolitan area. It is expected to be widely available by next spring. Learn more about Lucira's home COVID-19 test on its website.
