The device description details a turbidimetric immunoassay based on antibody-coated particles and absorbance changes, which is a standard laboratory technique and does not mention or imply the use of AI/ML. The performance studies focus on analytical and clinical validation metrics typical for in vitro diagnostic assays, not AI/ML model performance.
No
The device is an in vitro diagnostic (IVD) assay used to measure cystatin C, which aids in the diagnosis and treatment of renal diseases. It does not directly treat or cure the disease.
Yes
Explanation: The "Intended Use / Indications for Use" section explicitly states that the "Cystatin C measurements are used as an aid to the diagnosis and treatment of renal diseases." This clearly indicates its role in the diagnostic process.
No
The device description clearly indicates it is a reagent and calibrator kit for an in vitro diagnostic assay, which are physical components, 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." This is the most direct indicator.
- Nature of the Test: The device measures the concentration of cystatin C in human serum, heparinized plasma, and EDTA plasma. This is a laboratory test performed on biological samples outside of the body, which is the definition of in vitro.
- Purpose: The measurement is used as an "aid to the diagnosis and treatment of renal diseases." This indicates a medical purpose related to diagnosing and managing a health condition.
- Device Description: The description details a laboratory assay (sol particle turbidimetric immunoassay) and calibrators used in a laboratory setting.
All these factors confirm that this device is intended for use in a laboratory setting to perform diagnostic tests on biological samples, making it an In Vitro Diagnostic device.

Device Description
Genzymc Cystatin C assay reagent is based on the sol particle turbidimetric immunoassay principle. It contains colloidal gold particles coated with anticystatin C specific polyclonal antibodies. The reaction between the particles and any cystatin C in samples results in the formation of agglutinates and an associated change in absorbance signal. The change in absorbance signal is proportional to the amount of cystatin C in the sample. Cystatin C concentration in the sample is determined by comparison with a standard curve.
Genzyme Cystatin C calibrators consist of a bovine serum albumin liquid matrix with assigned concentrations of cystatin C. The calibrators are preserved with sodium azide and are ready to use.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Performance characteristics and data from nonclinical tests submitted in the premarket notification submission support a determination of substantial equivalence of the Genzyme Cystatin C devices with the Dade Behring predicate devices. This testing includes: analytical limits and sensitivity, within run and total precision testing over 20 days, linearity, reportable range, stability, analytical specificity, interfering substances, matrix comparison, and reference range. Method comparison studies performed with clinical specimens demonstrate comparable performance and accuracy, good correlation, and substantial equivalence.

Genzyme Cystatin C calibrators consist of a bovine serum albumin liquid matrix with assigned concentrations of cystatin C. The calibrators are preserved with sodium azide and are ready to use.
5. Device Intended Use:
Reagents:
The Genzyme Cystatin C assay reagent is an in vitro diagnostic test intended for the quantitative measurement of cystatin C concentration in human serum, heparinized plasma and EDTA plasma. Cystatin C measurements are used as an aid to the diagnosis and treatment of renal diseases. For In Vitro Diagnostic Use.
Calibrator:
Genzyme Cystatin C calibrator is an in vitro diagnostic product for the calibration of Genzyme Cystatin C assay. For In Vitro Diagnostic Usc.
6. Medical device to which equivalence is claimed and comparison information:
The Genzyme Cystatin C diagnostic test is substantially equivalent to the Dade Behring, Inc. N Latex Cystatin C method (K041878) with respect to the indications for use, the analyte tested, device design, the type of antibody materials, and the gencral sample matrix. The basic differences between the new device and the predicate are the assay technology and the instruments used for testing. The Genzyme device is a turbidimetric immunoassay that can be used on commercially available clinical analyzers using light absorption detection systems; while, the Dade Behring test is an immunonephelometric assay applicable only on Dade Behring, Inc. Nephelometer Systems.
The Genzyme Cystatin C calibrator is substantially equivalent to the Dade Behring N Protein Standard UY calibrator (K003501) with regard to the technological characteristics and in terms of the intended use. The difference is that the Genzymc calibrator is provided as a set of six liquid solutions of assigned cystatin C concentration levels and is ready to use for calibration; while, the Dade Behring N Protein Standard UY is a single lyophilized concentration of cystatin C calibrator that is prepared to various levels in order to establish values for calibration.
7. Device Performance Characteristics:
Performance characteristics and data from nonclinical tests submitted in the premarket notification submission support a determination of substantial equivalence of the Genzyme Cystatin C devices with the Dade Behring predicate devices. This testing includes: analytical limits and sensitivity, within run and total precision testing over 20 days, linearity, reportable range, stability, analytical specificity, interfering substances, matrix comparison, and reference range. Method comparison studies performed with clinical

specimens demonstrate comparable performance and accuracy, good correlation, and substantial equivalence.
8. Conclusion:
In conclusion, the new devices Genzyme Cystatin C Reagent and Genzyme Cystatin C Calibrator, do not raise any new issues of safety or effectiveness, and are substantially equivalent to the currently marketed Dade Behring devices N Latex Cystatin C test kit (K041878), and N Protein Standard UY calibrator (K003501) respectively, as demonstrated by the descriptions and performance data acquired by Genzyme and summarized in this submission.
