The Lucira Check It COVID-19 Test Kit is a molecular in vitro diagnostic test that has an analytical sensitivity, or ability to detect the SARS-CoV-2 virus, that is comparable to some of the best PCR molecular tests performed in clinical settings and high complexity labs. If SARS-CoV-2 is present in a sample, Lucira amplifies the virus’s genetic material while the test is running just like PCR lab tests. In the clinical studies described below, Lucira’s amplification method provides a level of accuracy comparable to one of the highest sensitivity lab PCR tests.

In two Community Testing Studies which included individuals with and without COVID-19 symptoms, the Lucira test was compared to the Hologic Panther Fusion, one of the highest sensitivity FDA authorized SARS-CoV-2 PCR tests. Lucira achieved 98% accuracy, 97% positive percent agreement (PPA) and 98% negative percent agreement (NPA)3, excluding samples with very low levels of virus that possibly no longer reflected active infection4. Across all data, and including 10 samples with very low viral loads (>37.5 Ct), Lucira achieved 96% accuracy, 92% PPA, and 98% NPA3.
Wondering what PPA and NPA are? In our studies, participants would swab themselves twice—for the Lucira test and a known high sensitivity PCR test. Then, we compared the Lucira test results to the PCR test results. Positive Percent Agreement (PPA), or sensitivity, represents how often the Lucira test agreed with the comparator PCR’s positive test results. Negative Percent Agreement (NPA), or specificity, represents how often the Lucira test agreed with the comparator PCR’s negative test results.
Lucira Community Testing Study Positive Percent Agreement (PPA) Summary
The above graph shows the Lucira Check It COVID-19 Test Kit positive percent agreement in Lucira’s two Community Testing Studies. BLUE bars represent samples where the Lucira positive test result matched the comparison test result. GREY bars represent the Lucira test results that were negative and did not match the comparison test positive result. Nearly all of the GREY bars occurred in samples where there were very low levels of virus detected by the comparison test.

The Lucira Check It COVID-19 test kit has not been FDA cleared or approved, but has been authorized for emergency use by FDA under an EUA.

Can you tell me more about Lucira’s PCR quality molecular accuracy?

The Lucira Check It COVID-19 Test Kit is a diagnostic test to detect SARS-CoV-2 which causes COVID-19. The test detects if you have an active infection and does not confirm immunity or detect antibodies. It is a molecular test that amplifies the virus’s genetic material while the test is running just like PCR lab tests. Lucira’s amplification method provides a level of accuracy comparable to one of the highest sensitivity lab PCR tests.

Can this test detect new SARS-CoV-2 variants?

Yes, Lucira detects 99.9% of known COVID-19 strains, including

  • Alpha (also known as B.1.1.7) first detected in UK,
  • Beta (also known as B.1.351, B.1.351.2, B.1.251.3) first detected in South Africa,
  • Delta (also known as B.1.617.2, AY.1, AY.2, AY.3) first detected in India,
  • Gamma (also known as P.1, P.1.1, P.2) first detected in Japan/Brazil,

Additional, two variants have been identified to be rising in prevalence:

  • Lambda (also known as C.37) first detected in Peru
  • Mu (also known as B.1.621) first detected in Colombia

Lucira Health performs routine surveillance of emerging SARS-CoV-2 strains and will continue to monitor the situation with emerging variants. We keep a Technical Brief on our website that lists the new strains we believe our test is reactive to.

How many times can I use this test?

Each test kit is single-use and comes with everything needed to run 1 Covid-19 test.

What’s the shelf life?

Currently, the test kit has a 12-month expiration. Note the FDA only allows COVID test product expiration dating to be supported by real time aging studies. We have continued real time aging studies underway and expect to update our expiration dating every three months. The next time we expect to update our expiration dating is in late November 2021.

Will this test hurt?
No, the nasal swab is not sharp and it should not hurt. Sometimes the swab can feel slightly uncomfortable or tickly.

What if I have questions about how to use this test when it arrives?
Each kit comes with instructions inside of it. You can see those instructions here, too. It’s important to carefully read and follow the instructions for the test to work properly. We also provide a video demonstration on our website.

What are the known potential risks and benefits of this test?
Potential risks include:

  • Possible discomfort during sample collection
  • Possible incorrect test results

Potential benefits include:

  • The results, along with other information, can help your healthcare provider make informed recommendations about your care.
  • The results of this test may help limit the spread of COVID-19 to your family and others in your community.

What’s an invalid result?
An invalid result means something with the test did not work properly. The chance of getting an invalid result is low. If the test result is invalid, all the lights on the device will be blinking. If your test shows an invalid result, please contact us at 1-888-582-4724. We will assist you and provide you a replacement test free of charge.

If I have other questions, how do I contact Lucira?
We're here for you. You can call Customer Service at 1-888-582-4724 or email us at info@lucirahealth.com.

How do I share my LUCI results?

Your LUCI PASS is stored in your LUCI account for 7 days and can be accessed by texting "RESULTS" to 44544 or by logging in to luci.lucirahealth.com.

How long is my LUCI PASS good for?

Your LUCI PASS lasts for 7 days and then will be cleared from your account. Check the requirements for where you plan to use your LUCI PASS, as many partners require test results within 48 or 72 hours (2-3 days).

How does LUCI PASS work for travel?

Lucira is a high performing PCR quality molecular test, equivalent to other tests accepted by most travel destinations.  LUCI PASS has also been designed to help you use it for travel.Your LUCI PASS will display:·        

  • Your verified test result, including the date and time of your test results·        
  • Information regarding Lucira’s accuracy, clinical performance and ability to detect Covid variants·        
  • A link to the FDA website that displays Lucira’s FDA Emergency Use Authorization (EUA)

While we believe Lucira’s test should be acceptable for most travel,  It is important to check with your airline and/or travel destination for further details and restrictions, as this may vary from destination to destination. 

Note that for state of Hawaii travel, Lucira is now available through Azova’s Hawaii Travel Program.

Can I use LUCI with the Lucira COVID-19 All-In-One (prescription) Test Kit?

Yes, you can obtain a LUCI PASS if your healthcare provider prescribes you the Lucira COVID-19 All-In-One Test. You will need the test kit box and your resulted device. Public health reporting is still the healthcare provider's responsibility even if the patient uses LUCI.

Will my personal or health information be shared?

LUCI can optionally transmit your test result to your state's public health authority. This is optional. Your test results are deleted from the LUCI system after 7 days. Lucira will not share your personal or health information without your express consent.
