The description details a standard in vitro diagnostic assay based on turbidity measurement, with no mention of AI or ML terms or functionalities.
No
This device is an in vitro diagnostic test designed to measure C-reactive protein levels, which aids in evaluating injury to body tissues. It does not provide therapy or treatment.
Yes
The device is described as an "immunological test system" that measures C-reactive protein to "aid in evaluation of the amount of injury to body tissues," which is a diagnostic purpose.
No
The device description clearly states it is an "in vitro assay" that uses "reagents" and measures "turbidity" optically. These are physical components and processes, 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's a "C-reactive protein immunological test system" used to "measure by immunological techniques the C-reactive protein in serum and other body fluids." It also mentions that the measurement "aids in evaluation of the amount of injury to body tissues." This clearly indicates it's a test performed in vitro (outside the body) on biological samples to provide information about a patient's health status.
- Device Description: The description further clarifies that it's an "in vitro assay for the quantitative determination of C-reactive protein in serum." It details the process of mixing a sample with reagents to create a reaction that is then measured optically. This is a typical description of an in vitro diagnostic test.
The key elements of an IVD are present: it's a test performed on a biological sample in vitro to provide diagnostic or health-related information.

Device Description
The Wako CRP test is a highly specific reagent based on turbidimetric immunoassay. When a sample is mixed with Buffer and Antibody, CRP in the sample combines specifically with anti-human CRP antibody (goat) in the Antibody to yield an insoluble aggregate that causes increased turbidity in the solution. The degree of turbidity of solution can be measured optically and is proportional to the concentration of CRP in the patient's sample.
The Wako CRP Calibrator and Wako CRP Calibrator Sct are designed to be used with the Wako CRP test.

Summary of Performance Studies
Precision studies indicate acceptable values can be obtained on a day to day basis. The minimum detectable level of this method is estimated to be 1 mg/L. The assay is lincar to 230 mg/L when using the Wako CRP Calibrator Sct and 200 mg/L when using the Wako single point CRP Calibrator.
Key Metrics
Minimum detectable level: 1 mg/L
Linearity: up to 150 mg/L (one-point calibration), more than 250 mg/L (multi-point calibrations), 230 mg/L (with Wako CRP Calibrator Sct), 200 mg/L (with Wako single point CRP Calibrator).

510(K) Summary of Safety and Effectiveness
Intended use
The Wako CRP test is an in vitro assay for the quantitative determination of C-reactive protein in serum.
Summary and explanation of the test
A protein that binds the C-polysaccharide on the cell wall of Streptococcus pneumoniae presents in the sera of acutely ill patients. This protein is called C-reactive protein (CRP), which has been recognized as one of the acute phase reactants that rise dramatically in the case of inflammation or tissue destruction. Determination of CRP is clinically useful for detecting. inflammation and infections. Various methods can be used for the determination of CRP (e.g. turbidimetric immunoassay (TIA), nephelometric immunoassay (NIA) and latex immunoassay (LIA). The Wako CRP test is a highly specific reagent based on turbidimetric immunoassay. 12 The Wako CRP test with one -point calibration shows the linearity up to 150 mg/L. The Wako CRP test with multi-point calibrations shows the linearity up to the highest value of calibrator set (more than 250 mg/L).
Principle of the method
When a sample is mixed with Buffer and Antibody, CRP in the sample combines specifically with anti-human CRP antibody (goat) in the Antibody to yield an insoluble aggregate that causes increased turbidity in the solution. The degree of turbidity of solution can be measured optically and is proportional to the concentration of CRP in the patient's sample.
Precision studies indicate acceptable values can be obtained on a day to day basis. The minimum detectable level of this method is estimated to be 1 mg/L . The assay is lincar to 230 mg/L when using the Wako CRP Calibrator Sct and 200 mg/L when using the Wako single point CRP Calibrator.
