Stratus® CS Acute Care™ Troponin Analyzer

The Stratus® CS Analyzer* for acute care diagnostics provides quantitative cardiac assays for fast, accurate evaluation of patients presenting with suspected myocardial ischemia. Its efficiency and ease of use make it ideal for both point-of-care testing and lab applications. 
  • Easy to use and ideal for all skill levels 
  • Full cardiac menu including guideline acceptable troponin I and D-dimer (with pulmonary embolism exclusion)** assays 
  • Results in as little as 14 minutes 
  • Use in the acute care setting to decrease turnaround time, patient length of stay, and total patient costs

Features & Benefits

Each year, more than eight million patients visit emergency departments in the United States with chest pain suggestive of myocardial ischemia. Yet, in around 75% of cases, objective evidence of unstable coronary syndrome is lacking after the initial clinical and ECG evaluation.

Accelerated diagnostic protocols using biochemical markers and near-patient testing strategies with the Stratus® CS analyzer can help address this challenge. Consequently, hospital stays—and the cost to manage both ACS-positive and ACS-negative patients—can be reduced.

Fast, informative results

  • Rapid turnaround time: 14 minutes to first result, and 4 minutes for each subsequent result
  • A broad menu of tests to support better chest pain differentiation from a single sample, on a single run, on a single instrument 

Easy-to-use in the Emergency Department, Coronary Care Unit, STAT Lab or Central Lab

  • Simple operation for all skill levels: load sample, rotor, TestPak™ Cartridge(s)—and press Start
  • System accepts blood directly from collection tube—no sample preparation, no manual dilutions
  • Integrated centrifuge spins whole blood to plasma and automatically pipettes to test cartridges—no user manipulation needed

Efficient and cost-effective

  • Eliminates manual intervention steps that prolong result turnaround
  • Single use packaging for tests, calibrators, and diluents reduce reagent waste
  • Select tests based on patient need—no fixed assay panels
  • System Check (electronic QC) reduces liquid QC frequency requirements


  • Barcode readers and lockout features for near-patient testing compliance
  • Fully compliant with OSHA Bloodborne Pathogens Preamble
  • First to the market with a guideline acceptable troponin I assay with the low end precision to meet the 2012 ESC/ACC Guidelines

Extensive Support

  • Onsite training
  • Field service group
  • Technical telephone support
