No.
The device is an in vitro diagnostic reagent used to measure CRP levels, not to treat a medical condition.
Yes
The device is for the "quantitative measurement of C-Reactive Protein (CRP) concentration in serum or plasma," which is used for In Vitro Diagnostic Use. Measuring biomarkers like CRP to aid in diagnosis or prognosis is characteristic of a diagnostic device.
No
The device is a reagent and calibrator for an in vitro diagnostic test, which are physical components used in a laboratory setting. It is not software.
Yes, this device is an IVD (In Vitro Diagnostic).
Here's why:
- Explicit Statement: The "Intended Use / Indications for Use" section clearly states: "For In Vitro Diagnostic Use."
- Nature of the Test: The device measures the concentration of C-Reactive Protein (CRP) in serum or plasma. This is a laboratory test performed on biological samples outside of the body, which is the definition of an in vitro diagnostic.
- Device Description: The description details a laboratory-based immunoassay using reagents and a calibrator to analyze a biological sample.
- Intended User/Care Setting: The intended user is in a "Clinical laboratory setting," which is where IVD tests are typically performed.

Device Description
The Genzyme N-geneous™ Wide Range CRP Reagent is a two-reagent method for the quantitative measurement of CRP concentration from 0.04 to 320 mg/L in serum or plasma.
The test is an enhanced latex-agglutination turbidimetric immunoassay. Sample is added to a buffer solution and mixed with a suspension of mouse anti-human CRP monoclonal antibody, which is bound to latex. CRP binds to the latex-bound antibody, which agglutinates. The light scattering caused by the increase in particle size is used as a measure of CRP concentration. The amount of light scattering is proportional to the concentration of CRP in the sample.
N-geneous™ Wide Range CRP Calibrator Set is a stabilized human serum designed to be used to calibrate the N-geneous™ Wide Range CRP Reagent and is sold separately. The Ngeneous™ Wide Range CRP Calibrator Set is traceable to CRM470, available from the Institute for Reference Materials and Measurements (IRMM), and certified by the European Commission, Community Bureau of Reference (BCR).

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Comparative performance studies were conducted using the N-geneous™ Wide Range CRP Reagent on the Hitachi 912 clinical analyzer and the Dade Behring N High Sensitive CRP method in which CRP was measured in 229 serum samples. The relationship between methods is:
N-geneous™ Wide Range CRP = 1.05 X (N High Sensitive CRP) – 0.31
Correlation coefficient (r) = 0.995
Precision studies were conducted using the N-geneous™ Wide Range CRP Reagent on the Hitachi 912 clinical analyzer. The studies were performed using sera that were stored frozen (-20°C) and thawed prior to use.
The N-geneous™ Wide Range CRP reagents yielded acceptable total precision.
These data demonstrate that the performance of the N-geneous™ Wide Range CRP Reagent in the clinical laboratory is substantially equivalent to the performance of a commercially available method.

The N-geneous™ Wide Range CRP reagents yielded acceptable total precision.
These data demonstrate that the performance of the N-geneous™ Wide Range CRP Reagent in the clinical laboratory is substantially equivalent to the performance of a commercially available method.
In addition, N-geneous™ Wide Range CRP Reagent is substantially equivalent to a currently marketed method, in that they measure the same analyte and have the same intended use. Additionally, they both use the same sample matrices and utilize mouse monoclonal antibody to CRP. Furthermore, they measure concentration by the magnitude of particle agglutination and light scatter, are in ready-to-use liquid format and both are traceable to CRM470 reference material. The N-geneous™ Wide Range CRP Reagent differs from the Dade Behring N High Sensitive CRP method in that the N-geneous™ Wide Range CRP Reagent utilizes a turbidimetric technique, whereas the Dade Behring N High Sensitive CRP
2
is a nephelometric method. Also, the reportable range of the N-geneous™ Wide Range CRP Reagent is up to 320 mg/L before dilution is required, whereas the Dade Behring N High Sensitive CRP method requires additional on board sample dilution for concentrations above 11 mg/L. The N-geneous™ Wide Range CRP Reagent uses a set of five standards for calibration; the Dade Behring N High Sensitive CRP method has one calibrator.
N-geneous ™ Wide Range CRP Calibrator Set is substantially equivalent to a currently marketed calibrator, the Dade Behring N Rheumatology Standard SL in that they are both used to establish calibration of CRP methods to be used for measurement of CRP in serum or plasma. Both are human serum-base materials that are traceable to CRM470 available from the Institute for Reference Materials and Measurements (IRMM), and certified by the European Commission, Community Bureau of Reference (BCR).
