It’s worth noting that we previously listed Ellume as a ‘home Covid test to avoid’ because it was recalled due to ‘more than acceptable false positive test results’ for Covid-19 in October and November 2021. In December, security researchers found they could fabricate positive or negative test results using Ellume’s Bluetooth-enabled test device. However, an Ellume spokesman says all affected tests have since been pulled from shelves and online retailers. Ellume tests currently available for purchase are safe to use and are not affected by the recall – the connected app will not let you proceed with the test if it is the recalled version. As for the hack, Ellume says it fixed the problem.
Warning: This test requires an app, so you should do it Check if your phone is compatible. You will receive a “Test Failed” result if the test is damaged, including from exposure to extremes of temperature or humidity.
The Clinitest Rapid Covid-19 comes with five tests per pack. For each test you will receive a sterile swab, a test cassette, a pre-filled extraction tube and a dropper tip. Swab each nostril five times, mix the swab with the solution, add four drops to the cassette and wait 15 minutes. If the test is positive, you will see two pink lines – one on the “C” line (control line) and another on the “T” line (test line). If it’s negative, you’ll only see a line next to the “C” on the cassette. I used this test and it is easy to do and understand.
In addition to home rapid antigen tests, you can also opt for a home molecular test. Antigenic tests (rapid tests) detect proteins on the surface of the virus, while molecular tests (usually known as PCR tests) detect the genetic material of the virus, usually making it more accurate. However, because PCR tests require a lab and a few days to get results, they are not as convenient as 15-minute rapid tests.
The molecular tests below use central hubs equipped with laboratory-grade technology. With the help of a few other accessories, these tests can provide PCR-like results within 15 minutes. It’s more helpful for those who travel frequently and/or work in industries that require being with large groups of people.
Cue Health’s home molecular test (7/10, WIRED recommends) is perhaps the most luxurious on the market (a phrase I never thought I’d say). If there weren’t his extremely high price (a cue reader and 10-pack of swabs will set you back a whopping $854) – even if you opt for one of the subscription-priced membership tiers) – I’d heartily recommend it for its ease of use alone (plus the 97, 8 percent accuracy). No solution, tubes, cassettes or test strips are required. Just open the connected app, insert a cartridge into the cue reader, swab your nose and insert the swab into the cartridge. After 20 minutes you will get the results on your phone. The company says its test has an accuracy rate of 97.8 percent.

Lucira does not require a smartphone, but you can download the Lucira Connect app to run a test recording. It’s easy to use – place the vial of solution in the reader, swab both nostrils, stir the swab in the solution, snap the vial closed and push further down into the reader. After 30 minutes you will see a green light next to the positive or negative label depending on the result. There is also an invalid result flag, which means you should retake the test.
