NCT04733170

Brief Summary

This is an international, multicentre, non-interventional, observational study to assess the clinical diagnostic performance of a rapid, point of care (POC) COVID-19 (SARS-CoV-2) antigen In vitro diagnostic (IVD), The KnowNow SARS-CoV-2 Rapid Antigen Test, using saliva samples when compared to reverse transcription polymerase chain reaction (RT-PCR) as the standard detection of COVID-19 infection.

Outcome Measures

Primary Outcomes (1)

  • Assess clinical diagnostic performance of the KnowNow SARS-CoV-2 Rapid Antigen Test

    This includes determination of the sensitivity/positive percent agreement (PPA), specificity/negative percent agreement (NPA), positive predicted value (PPV) and negative predictive value (NPV).

    6 months

Secondary Outcomes (2)

  • Efficacy to assess the test compared to the reference test method

    6 months

  • Usability Questionnaire to evaluate the use of the test with 2 saliva collection methods

    6 months

Interventions

KnowNow SARS-CoV-2 Rapid Antigen Test for the detection of Covid-19 in saliva, as compared to high sensitivity reverse transcription polymerase chain reaction (RT-PCR) of nasopharyngeal swabs as the reference test method
