Lab-Quality Performance

  • Sensitivity = 98.2%

    Sensitivity, or positive percent agreement (PPA), describes how well an assay correctly detects antibodies when the sample is positive. The LightDeck COVID-19 Total Antibody Test detected 56 of 57 positive samples.

  • Specificity = 99.4%

    Specificity, or negative percent agreement (NPA), was evaluated in a study with 320 samples. This high NPA leads to low false positive rates, allowing clinicians to deliver highly accurate results about immune response to the SARS-CoV-2 virus.

Critical Role of Antibody Testing

Determine past infection

Identify whether a person had been infected by SARS-CoV-2 and mounted an immune response.

Assess seroprevalence

Test for antibodies to determine the percentage of people in a community had a prior infection.
