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. 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.

No
The description focuses on a reagent and a nephelometer system for quantitative determination based on light scattering, with no mention of AI/ML terms or functionalities.

No.
Explanation: The device is an in vitro diagnostic reagent used to quantitatively determine C-reactive protein, not to treat any condition.

Yes

The "Intended Use" explicitly states that the proposed test reagent is "an in vitro diagnostic reagent," which directly indicates its diagnostic purpose.

No

The device is described as an in vitro diagnostic reagent, which is a chemical substance used in laboratory tests. It is intended to be used with a Behring Nephelometer System, which is a hardware instrument. The description focuses on the chemical reaction and the measurement of scattered light, indicating a physical component and process, not solely software.

Yes, this device is an IVD (In Vitro Diagnostic).

Here's why:

  • Intended Use/Indications for Use: The description explicitly states it 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." This directly aligns with the definition of an IVD, which is used to examine specimens derived from the human body to provide information for diagnostic purposes.
  • Device Description: The description details how the reagent works by reacting with C-reactive proteins in a sample (serum or plasma) to produce a measurable result (scattered light intensity) that is then used to determine the concentration of the protein. This process is performed in vitro (outside the living body).

The information provided clearly indicates that this reagent is designed to be used in a laboratory setting to analyze human biological samples for diagnostic purposes, which is the core function of an IVD.
