Near-patient settings with lab-quality results
Timeliness, effectiveness and safety are critical for acute care.1,2 Keeping this fact in mind, Siemens Healthineers Point of Care Diagnostics has designed the Stratus CS Acute Care Diagnostic System to best meet the requirements of the near-patient settings.

This solution is the ideal fit for near-patient testing. Intelligent design ensures ease of use and gold-standard quality results. It delivers the needed biomarkers to cover the spectrum of acute cardiac care.

The benefits of near-patient testing2,3
A study conducted using the Stratus CS Acute Care Diagnostic System to evaluate the impact of point-of-care testing with cTnI against routine testing documented several benefits of the system:
- For near-patient testing, turnaround time was shortened from 76 to 20 minutes
- 25% reduction in total costs for point-of-care cTnl testing


Caring for patients comes before handling specimens
Confidence in near-patient cardiac marker results
- Reduces time to 14 minutes compared to 60–120 minutes from the central lab
- Select from a robust diagnostic and risk stratification menu
- Less hands-on manipulation compared to hand-held devices decreases the opportunity for error
Easy to use by personnel of all skill levels4,5,6,7
- Daily maintenance is not needed
- Can be integrated into the information system of an institution
- Reduced risk of biohazard
- Closed whole blood sample processing using on-board centrifugation
Laboratory practices must be perfectly fulfilled
The Stratus CS Acute Care Diagnostic System is developed in compliance with laboratory accrediting agencies (CLSI, JCAHO, CAP). Daily system check with a programmable time lock-out includes:
- Fluid handling system
- Mechanical alignments
- Optical detection system
- Temperature
- Liquid control check and programmable time/range lock-outs are also available, if required by an institution or local regulations

Harmonizing the central lab and near-patient testing
“As more assay systems are devised for point-of-care (POC) testing, identical criteria must apply to both central laboratory methodologies and POC testing systems.”8
Siemens has been proactive in taking steps to ensure the alignment of cardiac Troponin I assays in the near-patient setting and central laboratory. cTnI and NT-proBNP need to be harmonized for laboratory medicine.8,9,10
The Stratus CS Acute Care cTnI assay has been shown to agree well with the Siemens central laboratory platforms (the Dimension Vista® Intelligent Lab System, Xpand® Plus integrated chemistry systems, and Dimension® RxL Max®) across the measurement range.
Siemens supplies the only point-of-care/central-lab pair of instruments that show real cTnI harmony,6,11,12 making the Stratus CS Acute Care Diagnostic System a perfect backup solution in satellite sites and central laboratories.
Guideline acceptable Troponin I
The preferred biomarker for myocardial necrosis8,9
- Meets internationally accepted guidelines (ESC/ACC/AHA/NACB/IFCC)8,9,11
- 10% CV at 0.06 ng/mL
- Excellent cardiac specificity and sensitivity13,14
- 99th percentile of normal: 0.07 ng/mL11,13
NT-proBNP15,16
Helps evaluate and manage acute coronary syndromes (ACS) and heart failure (HF)
- Additional risk factor for poor outcomes in ACS patients
- Early and accurate diagnosis
Myoglobin8,9
For patients who need early diagnosis
- Usable for reperfusion monitoring and re-infarction
- Outstanding negative predictive value can be rapidly observed in blood after injury
CardioPhase® CRP
Increases the prediction value of other markers employed for evaluating the risk of peripheral vascular and cardiovascular disease
- Inflammation contributing to plaque instability/rupture
CKMB mass8,9
An alternative solution to Troponin I
- Estimation of infarct-size14
- Usable for re-infarction detection17
Additional assays available on the Stratus CS Analyzer.
D-dimer18,19
An important test carried out on patients who are suspected of thrombotic disorders
- High precision at the cut-off level
- Outstanding sensitivity
- High negative predictive value for venous thromboembolism (VTE)
- Excludes pulmonary embolism (PE)*
βhCG20
For answering the question of pregnancy quickly and quantitatively to ensure the safest treatment possible
We found that a cTnl value of 0.07 ng/mL corresponded to the 99th percentile of a reference control population. A cTnI concentration of 0.06 ng/mL corresponded to a total imprecision of 10% CV for two
independent Stratus CS analyzers in routine use. Thus, the 10% CV for the Stratus CS cTnI assay is below the 99th percentile of a reference control population, and in compliance with specifications of the ESC/ACC** redefinition of MI.”11
R. Christenson et al., Clin Biochem 2004

First guideline acceptable Troponin I method
A guideline acceptable Troponin I method is defined by the joint ESC/ASCC committee as having an imprecision level of ≤10% at the 99th percentile of a normal population.8,9,11,21 The assay can be used for the measurement of cardiac Troponin I to aid in the diagnosis of acute myocardial infraction (AMI) and in the risk stratification of patients with acute coronary syndrome (ACS).13
