The Lucira Check It COVID-19 Test is a diagnostic tool to detect SARS-CoV-2, which causes COVID-19. The Lucira COVID-19 & Flu Test is a diagnostic tool to detect SARS-CoV-2, Influenza A, and Influenza B. The tests detects if you have an active infection and does not confirm immunity or detect antibodies. Each test 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.
Lucira detects all COVID-19 variants of interest and concern, including Omicron and its BA subvariants. Lucira performs routine surveillance of emerging SARS-CoV-2 and Influenza strains and will continue to monitor the situation with emerging variants.

The two most common types of influenza are influenza A & B. This test tests for both of these types of flu. If you test positive for either influenza A (Flu A) or influenza B (Flu B), you have the flu.
Each test is single use and comes with everything needed to run 1 molecular diagnostic test.
The Lucira COVID-19 and Flu Test has a shelf life of 12 months. The Lucira COVID-19 Test has a shelf life of 18 months; read our Note on Shelf Life Extension for more information.
Store and use Lucira between 59-86°F/15-30°C.
The test is indicated for self-collection for all people aged 14 years or older and for children as young as two years old when samples are collected by an adult.
No. The Lucira Check It COVID-19 Test only detects if you have an active SARS-CoV-2 (or COVID-19) infection and does not confirm immunity or detect antibodies. Similarly, the Lucira COVID & Flu Test only detects if you have an active SARS-CoV-2, Flu A, and/or Flu B infection and does not confirm immunity or detect antibodies.
Yes. Being vaccinated will not affect your Lucira test results.
No, these tests do not require a prescription from a medical professional. However, if you have questions about your health, you should contact your doctor. If you receive a positive result, you should contact your healthcare professional.
Sensitivity refers to a test’s ability to designate an individual with infection as positive. Specificity of a test is its ability to designate an individual who does not have an infection as negative.
There are two types of tests that detect for active infections: molecular and antigen tests. Molecular tests, such as PCR and Lucira, have higher sensitivity and can detect when virus is present in a sample at significantly lower viral levels versus antigen tests. Molecular tests copy the virus’s genetic material over and over while the test is running in a process called amplification. This allows molecular tests to detect whether someone is positive for the SARS-CoV-2 virus when only a small amount of virus is present.
Antigen tests, which are generally cheaper than molecular tests, do not copy or amplify the viral target and require much high levels of virus in a sample to be able to detect a positive result. In fact, antigen tests require 34 time1 more starting virus than molecular tests like Lucira to detect a positive. Several studies2 done in the UK and India report that the antigen tests used there are less sensitive than molecular tests and can more often result in false negatives.
Molecular tests are considered diagnostically definitive and do not typically require follow-up confirmatory testing. They are able to detect viruses across a broader range of viral loads, making them more sensitive and reliable.

Yes. The Lucira COVID-19 & Flu Test will determine the presence of SARS-CoV-2, which causes COVID-19, Flu A, and Flu B in your sample.
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.
Using Lucira is simple, even for people who have never tested themselves. Lucira tests use a shallow nasal swab, not a deep nasopharyngeal swab. All materials required to perform one Lucira test come in the box. Each test will include illustrated instructions that provide a step-by-step guide on how to use the test.
No, the nasal swab is not sharp and it should not hurt. Sometimes the swab can feel slightly uncomfortable or tickly.
Yes, collect the swab per instructions. Blowing your nose or having a runny nose will not affect the test performance.
Yes, you should follow the swabbing instructions.
No, if you have used a saline rinse or nasal spray you should wait 12 hours from administration of these sprays until you take the Lucira test.
The Lucira test can show a positive result in as little as 11 minutes while negative results take 30 minutes.
No, all the materials required to perform one Lucira test come inside the test box.
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.
Following each step of the instructions is important to avoid causing invalids. Test kits should only be used when you are ready to perform the test. The test pouches should not be opened and batteries should not be inserted until you’re ready to perform the test. Staging or setting tests up in advance of performing the test can cause invalid results.
Lucira Connect is a digital platform that can connect you with a telehealth provider to discuss care and treatment options if you test positive for COVID-19 or the flu. Antiviral treatments are more effective the earlier you take them. Lucira Connect is one of the fastest ways to treatment.
