Clinical Trial Summary

To evaluate the analytical and clinical sensitivity and specificity of antigen tests performed as oropharyngeal swabs, outer nasal swabs, saliva swabs or breath tests including self-tests for SARS-CoV-2 towards standard RT-PCR testing. For each test 200 SARS-CoV-2 positive and 200 SARS-CoV-2 negative individuals previously defined by RT-PCR are tested. When tested an additional RT-PCR test is performed to verify status. Analytical sensitivity and specificity is determined on 210 SARS-CoV-2 positive samples with known Cq and 100 SARS-CoV-2 negative samples. 30 companies with a total of 55 tests participate in this nationwide study.

Intervention

Diagnostic Test:
• Comparison of antigen tests with RT-PCR as reference method
Antigen tests are performed locally including sampling from multiple anatomical testing sites. A reference oropharyngeal swab is always send for RT-PCR for SARS-CoV-2 at DTU to verify the status of the patient. RT-PCR samples from other anatomical test locations may be included.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Clinical sensitivity and specificity of each antigen test compared to RT-PCR test result.	Performance is compared for each antigen test in relation to oropharyngeal RT-PCR samples collected simultaneously	Up to 3 days after first initial positive COVI-19 RT-PCR test
Primary	Analytical sensitivity and specificity of each antigen test on retrospectively collected SARS-CoV-2 positive and negative samples.	SARS-CoV-2 positive samples are stratified into subgroups according to Cq by RT-PCR and frozen samples in universal transport medium is tested on each antigen test.	2 months
Secondary	Clinical sensitivity compared to RT-PCR result with the later stratified into low, intermediate and high Cq	Performance of each antigen test in relation to the cycle of quantification Cq by RT-PCR stratified into low (Cq <25), intermediate (Cq 25-35) and High (Cq >35).	Up to 3 days after first initial positive COVI-19 RT-PCR test
Secondary	Agreement between oropharyngeal swabs and tests from other anatomical test locations by RT-PCR.	Antigen an RT-PCR tests are performed from multiple anatomical sampling sites on each teste individual.	Up to 3 days after first initial positive COVI-19 RT-PCR test.
