Stratus® CS Acute Care™ Diagnostic System

The Stratus® CS Acute Care™ Diagnostic System for 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.

Stratus CS in the Acute Care Setting

  • 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
  • Customize up to 4 tests to run on a single patient sample in your acute care setting, helping you make a quick diagnosis
  • 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
