Intended Use

Dimension Vista™ CRP Flex® reagent cartridge: The CRP method is an in vitro diagnostic test for the quantitative measurement of C-reactive protein (CRP) in human serum and heparinized plasma by means of particle enhanced immunonephelometry on the Dimension Vista™ System. In acute phase response, increased levels of a number of plasma proteins, including C-reactive protein, are observed. Measurement of CRP is useful for the detection and evaluation of infection, tissue injury, and inflammatory disorders. Dimension Vista™ Protein 2 Calibrator: Protein 2 Calibrator is an in vitro diagnostic product for the calibration of the C-reactive protein (CRP) method on the Dimension Vista ™ System. Dimension Vista™ Protein 2 Control L and H: Protein 2 Control L and H are for use as assayed intralaboratory quality controls for the assessment of precision and analytical bias in determination of C-reactive protein (CRP) on the Dimension Vista™ System.

Device Story

The Dimension Vista™ CRP Flex® reagent cartridge utilizes polystyrene particles coated with monoclonal anti-human CRP antibodies. When mixed with patient serum or heparinized plasma, CRP in the sample causes particle aggregation. The system passes a light beam through the sample; the intensity of scattered light is measured via immunonephelometry. This intensity is proportional to CRP concentration. The system evaluates results against a known standard. Used in clinical laboratory settings by trained personnel. Output provides quantitative CRP levels to assist clinicians in diagnosing and monitoring inflammatory conditions, infections, and tissue injury. System includes liquid human serum-based calibrators and quality controls to ensure analytical precision and bias assessment.

Clinical Evidence

Bench testing only. Method comparison study performed comparing Dimension Vista™ CRP assay to the predicate Dade Behring CardioPhase® hsCRP assay on the BN ProSpec® System. Analysis of samples (n=140) with concentrations ranging from 3.36 to 182.76 mg/L yielded a correlation coefficient of 0.997 and a slope of 0.985.

Technological Characteristics

Reagent: Polystyrene particles coated with monoclonal anti-human CRP antibodies. Measurement principle: Particle-enhanced immunonephelometry. System: Dimension Vista™ automated analyzer. Calibrators/Controls: Liquid human serum-based products. Connectivity: Integrated system component.

Indications for Use

Indicated for quantitative measurement of C-reactive protein (CRP) in human serum and heparinized plasma to aid in detection and evaluation of infection, tissue injury, and inflammatory disorders. Used on the Dimension Vista™ System.

Regulatory Classification

Identification

A C-reactive protein immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the C-reactive protein in serum and other body fluids. Measurement of C-reactive protein aids in evaluation of the amount of injury to body tissues.

#### 4. Device Description:

# Dimension Vista™ CRP Flex® reagent cartridge

Polystyrene particles coated with monoclonal antibodies specific to human CRP are aggregated when mixed with samples containing CRP. These aggregates scatter a beam of light passed through the sample. The intensity of the scattered light is proportional to the concentration of the respective protein in the sample. The result is evaluated by comparison with a standard of known concentration.

### Dimension Vista™ Protein 2 Calibrator

Protein 2 Calibrator is a liquid human serum based product containing C-reactive protein (CRP).

# Dimension Vista™ Protein 2 Control L and H

Protein 2 Control L and H are liquid human serum based products containing C-reactive protein (CRP).

#### 5. Device Intended Use:

### Dimension Vista™ CRP Flex® reagent cartridge:

The CRP method is an in vitro diagnostic test for the quantitative measurement of Creactive protein (CRP) in human serum and heparinized plasma by means of particle enhanced immunonephelometry on the Dimension Vista™ System. In acute phase response, increased levels of a number of plasma proteins, including C-reactive protein, are observed. Measurement of CRP is useful for the detection and evaluation of infection, tissue injury, and inflammatory disorders.

### Dimension Vista™ Protein 2 Calibrator:

Protein 2 Calibrator is an in vitro diagnostic product for the calibration of the C-reactive protein (CRP) method on the Dimension Vista ™ System.

### Dimension Vista™ Protein 2 Control L and H:

Protein 2 Control L and H are for use as assayed intralaboratory quality controls for the assessment of precision and analytical bias in determination of C-reactive protein (CRP) on the Dimension Vista™ System.

#### 6. Medical device to which equivalence is claimed and comparison information:

The Dimension Vista™ CRP Flex reagent cartridge, Dimension Vista™ Protein 2 Calibrator and Dimension Vista™ Protein 2 Control L and H are substantially equivalent to the Dade Behring CardioPhase® hsCRP assay (K033908) assay, N Rheumatology Standard SL (K964527) and N/T Rheumatology Control SL (K962373), respectively. The Dirension
Vista™ CRP assay, like the Dade Behring CardiPhase® hsCRP assay is an in vitro diagnostic reagent for the quantitative measurement of C-reactive protein (CRP) in human serum and plasma by means of particle enhanced immunonephelometry.

#### 7. Device Performance Characteristics:

The Dimension Vista™ CRP assay was compared to the Dade Behring CardioPhase®
hsCRP assay on the BN ProSpec® System by evaluating serum and plasma samples with concentrations ranging from 3.36 to 182.76 mg/L. Regression analysis of these results yielded the following equation:
