Intended Use

System reagent for the quantitative determination of Ceruloplasmin (CER) in human serum and plasma on Beckman Coulter AU analyzers as an aid in the diagnosis of copper metabolism disorders.

Device Story

Ceruloplasmin reagent kit; liquid, ready-to-use; used on Beckman Coulter AU clinical chemistry analyzers. Principle: immunoturbidimetric method; measures decrease in light transmission (increase in absorbance) through particles suspended in solution resulting from antigen-antibody complexes. Input: human serum or plasma samples. Output: quantitative Ceruloplasmin concentration (mg/L). Used in clinical laboratory settings by trained technicians. Healthcare providers use results to aid in diagnosis of copper metabolism disorders (e.g., Wilson's disease, malnutrition, liver disease). Benefits: provides diagnostic information for metabolic conditions.

Clinical Evidence

Bench testing only. Performance validated via precision (n=80), lot-to-lot reproducibility (n=75), linearity (17.37–2197.33 mg/L), and limit of quantitation (22.55 mg/L). Interference testing confirmed no significant impact from bilirubin, hemoglobin, triglycerides, or rheumatic factor. Method comparison against predicate (n=120) yielded slope 1.06, intercept -26.10, and correlation coefficient 0.99. Matrix comparison (serum vs. Li/Na-heparin plasma) showed high comparability (r=1.00).

Technological Characteristics

Turbidimetric immunoassay. Reagents: rabbit anti-human ceruloplasmin antiserum, polymer solution in Tris buffer (pH 7.4–7.6). Form factor: liquid, ready-to-use. Analyzers: Beckman Coulter AU series. Calibration: traceable to IFCC CRM470. Storage: 2–8°C. Software: embedded instrument control for automated calculation and dilution.

Indications for Use

Indicated for the quantitative determination of Ceruloplasmin in human serum and plasma to aid in the diagnosis of copper metabolism disorders.

Regulatory Classification

Identification

The Ceruloplasmin reagent kit is in a liquid, ready to use form. It is available in one format OSR6164 which consists of 4 x 18mL R1 vials and 4 x 5ml R2 vials. The calibrator is a Beckman Coulter Serum protein multi-calibrator ODR3023 which is sold separately. Ceruloplasmin is a turbidimetric method the basis for this method is the measurement of the decrease in light transmitted (increase in absorbance) through the particles suspended in solution as a result of complexes formed during the antigen-antibody reaction.

The Ceruloplasmin reagent is designed for optimal performance on the Beckman Coulter AU analyzers.

#### 6.0 Intended Use:

System reagent for the quantitative determination of Ceruloplasmin (CER) in human serum and plasma on Beckman Coulter AU analyzers as an aid in the diagnosis of copper metabolism disorders.

## Clinical Significance

Ceruloplasmin's main clinical importance is in the diagnosis of Wilson's disease. Increased levels of Ceruloplasmin are particularly notable in diseases of the reticuloendothelial system such as Hodgkin's disease and also during pregnancy or use of contraceptive pills. Low levels of ceruloplasmin are found in malnutrition, malabsorption, nephrosis and severe liver disease particularly biliary cirrhosis.
