Intended Use

The proposed test reagent (N Latex CRP mono Reagent) is an in vitro diagnostic reagent intended to be used together with the Behring Nephelometer Systems in the quantitative determination of C-reactive protein in human serum or plasma.

Device Story

In vitro diagnostic reagent; used with Behring Nephelometer Systems. Input: human serum or plasma samples. Principle: polystyrene particles coated with mouse monoclonal anti-CRP antibodies; agglutination occurs in presence of CRP; scattered light intensity measured by nephelometer. Output: quantitative CRP concentration determined via comparison to known standards. Used in clinical laboratory settings by trained personnel. Results assist healthcare providers in assessing inflammatory states. Benefit: provides rapid, accurate quantitative CRP measurement for clinical decision-making.

Clinical Evidence

Bench testing only. Comparative study of serum vs. plasma (EDTA and heparin) samples. Correlation coefficients: 0.998 (EDTA) and 0.999 (heparin). Slopes: 0.979 (EDTA) and 0.989 (heparin). Y-intercepts: 0.166 (EDTA) and 0.79 (heparin).

Technological Characteristics

Particle-enhanced nephelometric immunoassay. Reagent consists of polystyrene particles coated with mouse monoclonal antibodies. Energy source: nephelometer light source. Connectivity: integrated with Behring Nephelometer Systems.

Indications for Use

Indicated for the quantitative determination of C-reactive protein in human serum or plasma using particle-enhanced nephelometry.

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.

{0} Behring Diagnostics Inc. N Latex CRP mono Reagent 510(k) Notification K964687 DEC 1 6 1996 # 510(k) Summary of Safety and Effectiveness for the Behring N Latex CRP mono Reagent 1. Manufacturer Name, Address, phone number, contact name and date of preparation: Manufacturer: Behringwerke AG, Postfach 1140 35001 Marburg Germany Distributor: Behring Diagnostics Inc. 151 University Avenue Westwood, MA 02090 617 - 320 - 3153 Contact name: Laura LeBarron Date of preparation: September 11, 1996 2. Device name/Classification: In vitro diagnostic reagents for the quantitative determination of C-reactive protein (CRP) Class II (866.5270). 3. Identification of the legally marketed device to which the submitter claims equivalence: The Behringwerke N Latex CRP mono Reagent (K962523) 4. Proposed Device Description: The proposed test reagent (N Latex CRP mono Reagent) is an in vitro diagnostic reagent intended to be used together with the Behring Nephelometer Systems in the quantitative determination of C-reactive protein in human serum or plasma. CONFIDENTIAL 00008 {1} Behring Diagnostics Inc. N Latex CRP mono Reagent 510(k) Notification In the proposed product polystyrene particles coated with mouse monoclonal antibodies to C-reactive protein are agglutinated when mixed with samples containing C-reactive proteins. The intensity of the resulting scattered light in the nephelometer is dependent upon the C-reactive protein content so that, by comparison to standards of known concentration the C-reactive protein content of a sample can be determined. ## 5. Proposed Device Intended Use: The proposed test reagent (N Latex CRP mono Reagent) is an in vitro diagnostic reagent intended to be used together with the Behring Nephelometer Systems in the quantitative determination of C-reactive protein in human serum or plasma. ☑ ## 6. Medical device to which equivalence is claimed and comparison information: The N Latex CRP mono Reagent for use with serum or plasma samples is substantially equivalent in intended use and results obtained to the N Latex CRP mono Reagent (K962523) for use with serum samples. The N Latex CRP mono Reagent is intended to be used for the quantitative determination of C-reactive protein in human serum or plasma by particle enhanced nephelometry. ## 7. Proposed Device Performance Characteristics: ### Correlation Results of comparative serum versus plasma studies for both EDTA and heparin plasma samples using the N Latex CRP mono reagent gave correlation coefficients of 0.998 and 0.999, respectively, y-intercepts of 0.166 and 0.79, respectively, and slopes of 0.979 and 0.989, respectively.
