What is antigen testing?

  • Detects the presence of a specific viral antigen, most commonly the nucleocapsid protein
  • Typical sample types: nasopharyngeal, anterior nasal, and oropharyngeal swabs
  • Results are dependent on viral load and may not correlate with alternative technologies such as cell culture or NAAT/RT-PCR results. 1

COVID-19 Use Case

Omicron Update
Siemens Healthineers is committed to monitoring all current and emerging variants of concern (VOCs) by directly testing with clinical samples and using a computer-based inspection tool called in silico analysis. The Omicron variant (B.1.1.529) is recognized by the WHO, CDC, and ECDC as a VOC. Siemens Healthineers internal data demonstrate that the CLINITEST® Rapid COVID-19 Antigen (Self) Test detects SARS-CoV-2 virus/coronavirus infection of the Omicron variant and its major sub-variants, including BA.1, BA.2, BA.2.75, BA.3, BA.4, BA.4.6, BA.5, BF.7, and XE.
