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 NAAT/RT-PCR results2

Omicron Update
On November 26, 2021, the Omicron variant (B.1.1.529) was designated as a variant of concern (VOC) by the WHO, CDC, and ECDC. Siemens Healthineers’ internal assessments demonstrate that the CLINITEST® Rapid COVID-19 Antigen Test detects SARS-CoV-2 virus infection of the Omicron variant and its major sub-lineages, including BA.1, BA.2, BA.2.75, BA.3, BA.4, BA.4.6, BA.5, and XE. Siemens Healthineers is committed to monitoring all current and emerging variants of concern to ensure the test results remain accurate and reliable.
