Intended Use

The Sentinel Plasmaproteins Cal 3x is a device intended for medical purpose for use in ceruloplasmin, kappa light chains and lambda light chains assay to establish points of reference that are used in the determination of values in the measurement of ceruloplasmin, kappa and lambda light chains in human serum and plasma.

Device Story

Sentinel Plasmaproteins Cal 3x is a liquid, ready-to-use calibrator derived from human-based serum. It provides reference points for quantifying ceruloplasmin, kappa light chains, and lambda light chains in human serum and plasma samples. Used in clinical chemistry laboratories with automated, semi-automated, or manual systems. The calibrator is traceable to CRM 470 (Certified Reference Material). It assists healthcare providers by ensuring accurate calibration of immunoturbidimetric assays, thereby supporting reliable diagnostic measurements for the specified proteins.

Clinical Evidence

No clinical data. Bench testing only. Stability and shelf-life (24 months) were validated by recovery methods comparing stored lots to manufacturing-time assigned values, with acceptance criteria of 100±10%. Traceability to CRM 470 was established.

Technological Characteristics

Liquid, ready-to-use calibrator in human serum matrix. Contains ceruloplasmin, kappa light chains, and lambda light chains. Traceable to CRM 470. Storage at 2-8°C. Compatible with automated, semi-automated, and manual clinical chemistry systems.

Indications for Use

Indicated for use as a calibrator to establish reference points for the measurement of ceruloplasmin, kappa light chains, and lambda light chains in human serum and plasma.

Regulatory Classification

Identification

A calibrator is a device intended for medical purposes for use in a test system to establish points of reference that are used in the determination of values in the measurement of substances in human specimens. (See also § 862.2 in this part.)

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 § 862.9.

## Description of the Calibrator Material:

Sentinel Plasmaproteins Cal 3x contains analytes (plasmaproteins) in human Schumer i lasthup been
serum matrix. The analytes consist of ceruloplasmin, kappa light chains, and lambda light chains.

# Assigned Values and Value Assignment Process:

The Sentinel Plasmaproteins Cal 3x value assignment is assessed by testing the new lot The belief.

In the assignment testing, five replicates per three runs are assessed for Kappa light in the assigninent as a Ceruloplasmin assays. The assigned value is calculated is as the average of all the replicates for each assay.

Quality control materials are used to verify the assay performance at every step of the test. Fresh reagents and new calibrations are used at each run.

### 7. Calibrator Shelf-life Stability

The calibrator shelf-life stability was determined by the recovery method on one lot of Plasmaproteins Cal 3x stored at 2 – 8 °C, compared with the value assigned at manufacturing time. Percent recovery was calculated for each calibrator level by dividing the result in conventional units (mg/dL) of the test calibrators by the assigned value (mg/dL) and multiplying the result by 100. Acceptance criteria is 100 ± 10 %. At each testing point. Data support a shelf life of 25 months. Claim will be 24 months. Results are reported in the table below.
