JOINSTAR COVID-19 rapid antigen test (spit test).

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

The COVID-19 antigen rapid test is suitable for the qualitative detection of novel coronaviruses in saliva, sputum (each from the posterior oropharyngeal area) and stool samples. No invasive sampling is necessary to carry out the test, so the rapid test is particularly user-friendly. This SARS-CoV-2 Antigen Rapid Test Kit uses an immunocapture method to check for the presence or absence of SARS-CoV-2 nucleocapsid proteins in the samples. After a sample has been processed and fed to the test device, the SARS-CoV-2 antigens present in the sample are bound to antibodies that are conjugated to colloidal gold in the test strip. The antigen-conjugate complexes migrate via the test strip into the reaction area and are picked up by a number of antibodies that are bound to the membrane. A colored band indicates when the antigen conjugate is deposited at test position “T” and control position “C” on the device. The deposits indicate the result.

Features of the test:

  • Sample material: oropharyngeal saliva, sputum or stool.
  • Diagnostic sensitivity: 90.00 percent for oropharyngeal saliva and 95% for sputum and stool.
  • Diagnostic specificity is 100.00 percent for posterior oropharyngeal saliva sample. CI: 88,43% ~ 100%.
  • Finished sampling tube filled with buffer solution.
  • Quick result in just 15 minutes.
  • BfArM listed.
  • CE certified.
