High-throughput SARS-CoV-2 Antigen Assay

High-throughput SARS-CoV-2 Antigen Assay

Lab-based antigen testing for rapid virus detection: Time to first result in as little as 26 minutes

High-throughput, central lab-based SARS-CoV-2 antigen testing is a cost-effective and highly scalable complement to molecular RT-PCR diagnostic testing in the fight against COVID-19 by:

  • Increasing testing capacity to support testing of large groups and organizations.
  • Detecting positive cases quickly, allowing timely follow-up and implementation of protective measures.
  • Providing accurate results, including for patients who are asymptomatic or in the early stage of the disease.
  • Protecting your laboratory staff by inactivating the virus with a pretreatment.

The SARS-CoV-2 Antigen Assays are available on the Atellica® IM Analyzer and ADVIA Centaur® XP/XPT Systems.

Importance of Monitoring Emerging SARS-CoV-2 Variants to Ensure Antigen Assay Effectiveness White Paper

Importance of Monitoring Emerging SARS-CoV-2 Variants to Ensure Antigen Assay Effectiveness White Paper

The continued emergence of broadly-circulating SARS-CoV-2 variants has raised significant concerns about vaccine efficacy.1-3

This new whitepaper discusses the differences between mutants, variants, and strains, and how they might affect SARS-CoV-2 antigen testing. Learn about Variants of Concern (VOCs) and how enhanced surveillance supports earlier identification.

Because of their increased risk to public health, Siemens Healthineers is committed to the continuous monitoring of emerging variants and conducting evaluations to help ensure that our assays remain effective at detecting them. Our SARS-CoV-2 Antigen assay features antibodies that maximize variant detection, including the Omicron and Delta variants.

Large Scale Testing

Demand for testing continues to increase, placing great pressure on large organizations and communities to efficiently identify COVID-19 infection. Lab-based antigen testing can be easily integrated on currently available high-throughput instruments already being used for routine diagnostic testing at clinics, reference labs, and hospitals today or can be installed at a mass testing site.

Suspected COVID-19 Outbreaks Icon

Suspected COVID-19 outbreaks 

  • In remote settings, institutions, and semi-closed communities where PCR is not immediately available.
  • Positive results from multiple patients may suggest an outbreak and would allow for earlier implementation of infection control measures.
Domestic and International Traveler Testing Icon

Domestic and International Traveler Testing

  • Efficient and scalable passenger testing for airports, train stations, and cruise ships.
  • More effective identification of at-risk individuals to rapidly isolate positive cases (and initiate other contact tracing efforts) and prioritize sample collection for PCR confirmation as needed.
Large Organizations and Facilities Icon

Large Organizations and Facilities

  • Ongoing monitoring to help prevent widespread infection within institutions and workplaces such as schools, offices, dormitories, factories, correctional institutions, medical facilities, etc.
  • Areas of widespread community transmission where the positive predictive value and negative predictive value of an antigen result are sufficient to enable effective infection control.

Siemens Healthineers SARS CoV-2 Antigen Tests

  • Enable high-volume capacity for testing large organizations and crowded facilities
  • Produce accurate results with rapid turnaround time, at reduced costs
  • Provide automated result reporting
