Indications for Use
The IMMAGE Immunochemistry System Ceruloplasmin (CER) Reagent, when used in conjunction with Beckman IMMAGE™ Immunochemistry Systems and Beckman Calibrator 2, is intended for the quantitative determination of human ceruloplasmin by rate nephelometry.
Device Story
The IMMAGE Immunochemistry System Ceruloplasmin (CER) Reagent is an in vitro diagnostic reagent used on the Beckman IMMAGE Immunochemistry System. It utilizes rate nephelometry to measure ceruloplasmin concentrations in human serum. The system processes samples by reacting them with goat-derived anti-ceruloplasmin antibodies; the resulting light scattering is measured to quantify the analyte. The device is intended for use in clinical laboratory settings by trained laboratory personnel. The output provides quantitative ceruloplasmin levels, which assist clinicians in assessing patient health status and diagnosing relevant clinical conditions.
Clinical Evidence
Bench testing only. Performance was validated through method comparison, stability, and imprecision studies. Method comparison against the Array 360 System (n=104) yielded a slope of 0.996, intercept of -2.43, and r=0.995. Imprecision studies (n=80 per level) demonstrated within-run CVs of 2.4-3.1% and total CVs of 3.5-4.3% for serum levels 13.6-88.0 mg/dL. Low-level precision (n=30) showed total CVs of 3.9-6.6%. Shelf-life and stability claims are 24 months and 14 days, respectively.
Technological Characteristics
Rate nephelometry-based immunochemistry reagent. Uses goat-derived anti-ceruloplasmin antibodies. Designed for use on the Beckman IMMAGE Immunochemistry System. Reagent volumes and antibody concentrations are optimized for the IMMAGE platform compared to the predicate Array system.
Indications for Use
Indicated for the quantitative determination of ceruloplasmin concentrations in human serum samples to aid in the diagnosis of ceruloplasmin-related conditions.
Regulatory Classification
Identification
A ceruloplasmin immunological test system is a device that consists of the reagents used to measure by immunochemical techniques the ceruloplasmin (copper-transporting serum protein) in serum, other body fluids, or tissues. Measurements of ceruloplasmin aid in the diagnosis of copper metabolism disorders.
Special Controls
*Classification.* Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 866.9.
