Description

NADAL® COVID-19 Ag rapid test.

Rapid test for the detection of viral SARS-CoV-2 nucleoprotein antigens in human nasopharyngeal and oropharyngeal samples.

– Listed by the German Federal Institute for Drugs and Medical Devices (BfArM) –

The NADAL® COVID-19 antigen rapid test delivers highly precise results in a few minutes, costs only a fraction of a PCR test and saves laboratory capacity.

The NADAL® COVID-19 Antigen Rapid Test – a chromatographic immunoassay in lateral flow format – checks for protein fragments of the virus and thus for its direct, physical presence in the body. It is done with the help of a swab taken from the mouth or nasopharynx. This is enriched in a buffer solution and then pipetted onto the test cassette. A qualitative result is available in less than 20 minutes.

The diagnostic sensitivity is 97.56% (ct value: 20 – 30), the diagnostic specificity is >99.9%. This means that positive results from antigen tests are very accurate. However, since there is always a residual risk of a false negative result, it is advisable to carry out a PCR test to confirm negative results in case of doubt. There is no elimination procedure between antibody, antigen and PCR tests. Rather, their combined use is tactically smart. Because – to the U.S. To quote the Food and Drug Administration (FDA):

“Each category of diagnostic test has its own unique role in the fight against this virus.”

The importance of the antigen test

While the NADAL® COVID-19 IgG / IgM rapid test detects the virus indirectly, the NADAL® COVID-19 antigen rapid test detects the virus directly by checking for the presence of specific SARS-CoV-2 proteins. Antigen detection thus closes a diagnostic gap. The nucleocapsid protein (N) is ideally suited for this detection, as it occurs very frequently in the virus and is sufficiently specific for SARS-CoV-2. It is one of its 4 most important structural proteins and is involved in the replication, transcription and packaging of the viral genome.

The NADAL® COVID-19 Antigen Rapid Test is a chromatographic immunoassay in lateral flow format for the qualitative detection of viral SARS-CoV-2 nucleoproteins in human nasopharyngeal and oropharyngeal samples. The test is intended as an aid in diagnosing SARS-CoV-2 infections. It should be noted that the concentration of the viral nucleoprotein antigens fluctuates in the course of the disease and can fall below the detection limit of the test. A possible infectiousness of the test persons cannot be excluded due to negative test results.
