High-throughput SARS-CoV-2 Antigen Assay

High-throughput SARS-CoV-2 Antigen AssaysLab-based antigen testing for rapid virus detection: Time to first result in as little as 26 minutes

SARS-CoV-2 antigen testing has emerged as an important tool to support molecular RT-PCR diagnostic testing in the fight against COVID-19. High-throughput antigen assays help to verify infection quickly so that healthcare providers can begin treatment immediately or initiate isolation precautions to prevent further spread of infection. Improve your confidence in SARS-CoV-2 mass screening with a high-throughput, central lab-based antigen assay that can quickly provide accurate results in at-risk individuals, including patients who are asymptomatic or in the early stage of the disease.

The SARS-CoV-2 Antigen Assays are now available on the Atellica® IM Analyzer and ADVIA Centaur® XP/XPT Systems:
  • Helps you gain time, confidence, and resources back while increasing testing capacity.
  • Quickly detects positive cases, allowing timely follow-up and implementation of protective measures.
  • Protects your laboratory staff by inactivating the virus with a pretreatment.

Why Antigen Testing

Since the beginning of the COVID-19 pandemic, nucleic acid amplification tests (NAATs) such as PCR tests have been used to detect the virus. But in many countries, shortages of laboratory-based molecular testing have been challenging, and prolonged turnaround times for NAATs may preclude their clinical utility.

High-throughput SARS-CoV-2 antigen (Ag) assays:

  • Play a significant role in early detection and isolation of positive cases
  • Reduce the time to reportable results compared to lab-based PCR testing
  • Can be used as an alternative method if PCR is not available
