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.
