ADVIA Centaur TnI-Ultra® Assay
The ADVIA Centaur® TnI-Ultra® assay provides clinicians with confidence to accurately rule out/in early acute myocardial infarction. The Acridinium Ester-based ADVIA Centaur TnI-Ultra assay is a highly precise assay that can measure very low concentrations of cardiac troponin I. This excellent precision exceeds the industry benchmark established by the Joint European Society of Cardiology/American College of Cardiology Committee of ≤10% CV at the 99th percentile of normal. The assay uses the patented high quantum yield AE (HQYAE) molecule which improved the analytical sensitivity by a factor of 5 over the previous ADVIA Centaur cTnI assay.

  • Supports rapid triage of chest pain patients and improves acute care workflow between serial measurements (6h reduced to 3h protocols) with a time to first result in 18 minutes or less.
  • Delivers confidence in the earlier detection of AMI with demonstrated clinically equivalent to high-sensitive cardiac troponin assays, meeting the guidelines criterion for ≤10%CV at the 99th percentile
  • Provides reliability in results with almost a decade in clinical practice
