The sensitivity of a test indicates how well an antigen rapid test detects a COVID-19 infection. It is an important quality criterion and shows the reliability of a test. Find out why reliability is important and what quality standards apply to rapid tests.

Playing It Safe: Why Reliability Matters

Antigen rapid tests are often performed when symptoms of COVID-19 infection appear. However, it is well known that infections can also occur asymptomatically, without classic symptoms. To reliably detect an infection, rapid tests are important that can detect COVID-19 infection. Asymptomatic infections or infections in early stages can be detected early in this way. This makes it possible to isolate the sick person as quickly as possible to prevent transmission. Additionally, reliable tests save costs, as only one test needs to be performed instead of multiple tests for confirmation. But what are the decisive factors for rapid test reliability?

Factors of Reliability

Sensitivity: Sensitivity indicates the "hit rate" of a test kit – in other words, how reliably infected persons are detected at high viral load. A sensitivity of 100 percent means that all infected persons can be detected using the test. The viral load – how strongly the virus has already multiplied in the nasopharyngeal area – is crucial for detection accuracy. Antigen rapid tests were originally developed to detect highly infectious patients. Therefore, most test kits work most reliably at high viral loads.

Specificity: Specificity shows how reliably a test identifies negative cases – in other words, how reliably healthy persons are recognized as healthy. High specificity (at least 97-99%) is important to minimize false-positive results.

Quality Criteria: According to the standards of BfArM, PEI, and RKI, tests should have sensitivity greater than 80% and specificity greater than 97%. Tests below these minimum requirements are removed from official lists.

Assessing Rapid Test Quality

How can you find out what sensitivity a particular antigen test has? There are various information sources: manufacturer specifications on the package, data sheets, and test reports. Websites such as rapid test evaluation also help compare the characteristics of different tests. In practice, you can also scan the barcode to get information.

Choosing a High-Quality Rapid Test

There is a large selection of antigen rapid tests on the market with different quality standards. Overall, regulatory agencies such as the Paul Ehrlich Institute (PEI) have reviewed over 200 antigen rapid tests in the past. Many tests meet the high quality requirements, but some fail due to insufficient sensitivity. According to international standards, tests should meet the following criteria:

• Sensitivity above 80%, ideally 90% or higher
• Specificity above 97%
• Certification by national or international authorities
• CE marking and clinical tests

High-quality tests provide reliable results and enable rapid testing. They are particularly valuable for medical professionals, hospitals, and care facilities that require professional quality standards.
