Intended Use
The CRP (Latex) High Sensitive Immmunoturbidimetric assay is for the in vitro quantitative determination of C-reactive protein (CRP) in human serum and plasma on Roche automated clinical chemistry analyzers. Measurement of CRP is of use for the detection and evaluation of inflammatory disorders and associated diseases, infection and tissue injury. Highly sensitive measurement of CRP may also be used as an aid in the assessment of the risk of future coronary heart disease. When used as an adjunct to other laboratory evaluation methods of acute coronary syndromes, it may also be an additional independent indicator of recurrent event prognosis in patients with stable coronary disease or acute coronary syndrome.
Device Description
The CRP (latex) HS Test System is a latex particle-enhanced immunoturbidimetric test for the quantitative measurement of C-reactive protein in human serum or plasma. Human CRP agglutinates with latex particles coated with monoclonal anti-CRP antibodies. The precipitate is determined turbidimetrically. The calibrator is the Calibrator for automated systems (C.f.a.s). Proteins; and the recommended control materials are CRP T Control N and Precinorm Protein.
More Information

Not Found

No
The device description details a standard immunoturbidimetric assay for measuring CRP, which relies on chemical reactions and turbidimetric detection, not AI/ML algorithms. The document explicitly states "Not Found" for mentions of AI, DNN, or ML, and there is no description of training or test sets, which are typical for AI/ML-based devices.

No.
This device is an in vitro diagnostic immunoassay that measures CRP levels in human samples to aid in diagnosis and risk assessment, not to treat or directly restore health.

Yes

The device quantitatively determines C-reactive protein (CRP) levels, which are used for the "detection and evaluation of inflammatory disorders and associated diseases, infection and tissue injury," and as an "aid in the assessment of the risk of future coronary heart disease," fitting the definition of a diagnostic device.

No

The device is a laboratory assay kit, which includes reagents and is used on automated clinical chemistry analyzers. This involves physical components and chemical reactions, not solely software.

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

Here's why:

  • Intended Use: The "Intended Use / Indications for Use" section explicitly states that the assay is "for the in vitro quantitative determination of C-reactive protein (CRP) in human serum and plasma". "In vitro" means "in glass" or "outside the body," which is a key characteristic of IVDs.
  • Sample Type: The device analyzes human serum and plasma, which are biological specimens taken from the body.
  • Purpose: The purpose is to measure a substance (CRP) in these specimens to aid in the diagnosis and evaluation of medical conditions (inflammatory disorders, infection, tissue injury, and risk of coronary heart disease). This is the core function of an IVD.
  • Device Description: The description details a "latex particle-enhanced immunoturbidimetric test," which is a laboratory method used to analyze biological samples.

All of these points align with the definition of an In Vitro Diagnostic device.

diagnostic reagent for the quantitative
determination of C-reactive protein
(CRP) in human serum, and heparin and
EDTA plasma by means of particle-
enhanced immunonephelometry using
BN Systems. 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, inflammatory
disorders, and associated diseases.
Measurements may also be used as an aid
in the identification of individuals at risk
for future cardiovascular disease. High
sensitivity CRP (hsCRP) measurements,
when used in conjunction with traditional
clinical laboratory evaluation of acute
coronary syndromes, may be useful as an
independent marker of prognosis for
recurrent events, in patients with stable
