The CLINITEST Rapid COVID-19 Antigen Test8 helps identify infected individuals in just 15 minutes anywhere. The easy-to-use visual read test does not require specialized lab personnel or instruments, offering the flexibility to test in locations that benefit from immediate results but have limited access to laboratory resources. The test only requires a nasal swab from both nostrils. The swab is then washed in a reagent, dissolving a specific protein from the surface of the virus. This liquid is dropped into a well in the test cassette. Within 15 minutes, the test sample flows into the field of view of the cassette and becomes visible by a dash. The position and number of lines indicate whether the test result is positive or negative, or whether something was done incorrectly during the test procedure and the test must be repeated.
Antigen test: Know if you have COVID-19, fast
PCR tests are still the gold standard for SARS-CoV-2 testing when it comes to accuracy. However, they can also present challenges: the delivery of test results may take some time and PCR tests don’t have the high throughput capability of an automated test. That’s where antigen tests come in. There are two types: a simple, visual read test for individual people and a lab-based, automated test for large quantities of patient samples.
Limiting spread and containing outbreaks
A person with COVID-19 on average infects two or more other people.3,4 The tricky part: While they are infectious, people are often not aware that they have the disease because they do not (yet) display any typical symptoms. Given the high infection rate and the environmental stability of the virus, it is vital to identify infected individuals as early as possible, so that they can seek medical guidance and self-isolate. On a larger scale this of course also helps to reduce the overall spread of the virus. Antigen tests and PCR tests help here.
Minimizing individual risk and informing action
To understand the bigger picture of the actual disease spread and to determine an individual’s risk, it is also important to know, if a person was already exposed to the virus and infection has resolved. Some tests may detect antibodies that neutralize the virus and growing research shows that these antibodies may indicate immunity.5,6,7 If immunity is proven, such antibody tests could for example help decide if workforce can safely return to a workplace where social distancing is a challenge, in conjunction with antigen testing and/or PCR testing.
Testing large groups of people fast
When it comes to testing large quantities of patient samples quickly and cost-effectively, our lab-based SARS-CoV-2 Antigen Assay9 is an ideal tool. For example at on-site collection centers for hospital staff, patients and visitors, remote collection facilities for large scale testing of local populations or in dedicated, pop-up labs at airports or large universities. The test was designed with the objective to maximize sensitivity to both current and future SARS-CoV-2 variants. It shows strong alignment to PCR methods with sensitivity exceeding 94% and specificity at 100% for the Atellica IM COVAg test.10 With availability of CoV2Ag on the Atellica IM Analyzer, laboratories can significantly increase the SARS-CoV-2 testing capacity with a platform that can run up to 440 tests per hour.11
