EuGeni Rapid Antigen Test for the Qualitative Detection of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Causing COVID19 Disease in Compliance With the World Health Organization (WHO)
Study Details
Study Description
Brief Summary
Rapid antigen detection (RAD) tests are used to perform rapid diagnosis of SARS-CoV-2 infection based on a qualitative approach. RAD tests detect the viral antigen by the immobilized coated SARS-CoV-2 antibody placed on the device. The results of these tests are available in a short time, reducing the workload in diagnostic hospitals and laboratories and improving the turn-around time.
EuGeni SARS-CoV-2 Antigen Rapid Diagnostic Test is an in vitro Diagnostic (IVD) medical device intended to be used for the qualitative detection of SARS-CoV-2 nucleocapsid antigen. The result from this IVD test identifies the presence or absence of the SARS-CoV-2 antigen as an aid for the diagnosis of COVID-19 infection.

Detailed Description
The EuGeni SARS-CoV-2 Antigen (Ag) Rapid Detection Test (RDT) is a test strip based on lateral flow technology which utilizes nanoparticles, doped with europium, as the fluorescence reporter system. The test strip is housed in a cassette which is read by the EuGeni AX-2X-S Reader, a portable instrument that reads EuGeni fluorescent lateral flow tests.
The test line contains an immobilized monoclonal mouse antibody to capture SARS-CoV-2 antigen and the control line contains an immobilized control anti-mouse antibody.
The test sample is added to the sample well of the test cassette and then reconstitutes the dried europium nanoparticle antibody conjugate from the conjugate pad. The sample flows along the test strip by capillary action.
If the sample contains SARS-CoV-2 antigen, it binds to the antibody-labelled europium nanoparticle. When the sample flows past the test line, the europium bound antigen is captured by the second anti-SARS-CoV-2 antibody immobilized on the test line. A fluorescent signal detected by the EuGeni AX-2X-S Reader at this test line indicates that the specimen is SARS-CoV-2 antigen Positive.
If the sample does not contain SARS-CoV-2 antigen, the europium-labelled anti-antigen antibody will not bind to the test line. This indicates that the specimen is SARS-CoV-2 antigen Negative.
The sample continues to flow along the strip and when it passes over the control line, antibody-labelled europium nanoparticles are captured by the immobilized anti-mouse antibody. The control line must be detected by the EuGeni AX-2X-S Reader for the test to be valid. If the control line is not detected, the test is considered invalid and must be repeated using another test cassette.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Nasopharyngeal specimen collection arm Specimens collected in nasopharyngeal form from positive subjects with symptoms and negative subjects hospitalized and negative subjects with respiratory symptoms. |
Diagnostic Test: EuGeni SARS-CoV-2 Antigen Rapid Diagnostic Test
Subjects have two swabs taken for analysis, one (combined or nasopharyngeal) with the kit under investigation and the other (by standard of care) for analysis with PCRl.
|
| Combined nasal mid-turbinate and throat specimen collection arm Specimens collected in combined nasal mid-turbinate form from positive subjects with symptoms and negative subjects hospitalized and negative subjects with respiratory symptoms. |

Outcome Measures
Primary Outcome Measures
- Diagnostic sensitivity and specificity in terms of true positive results and true negative results between the kit under investigation and the gold-standard PCR [Through study completion, an average of 4 months]
Number of true positives and true negatives in terms of sensitivity and specificity (accuracy) by contrasting the result obtained with the investigational kit and the gold-standard PCR result.
Secondary Outcome Measures
- The sensitivity and the specificity values between the two collection methods, nasal and nasopharyngeal. [Through study completion, an average of 4 months]
To compare the sensitivity and specificity value translated as true positives and true negatives between the investigational kit and PCR between the two sample collection methods, nasal and nasopharyngeal.
