Intended Use

ISE Compensator is for use in the calibration of Ion Selective Electrodes on Roche/Hitachi analyzers.

Device Story

ISE Compensator is a ready-to-use liquid calibrator for Ion Selective Electrodes (ISE) on Roche/Hitachi analyzers. It consists of a buffered human serum matrix containing defined concentrations of sodium, potassium, and chloride, plus stabilizers. The device is used by laboratory personnel to calibrate ISE modules on compatible analyzers. It provides a reference point for measuring electrolyte concentrations in patient samples. The human serum matrix is screened for HBsAg, HCV, and HIV. The product is supplied in 1 mL bottles.

Clinical Evidence

No clinical data. Performance was established through bench testing, specifically evaluating value assignment and stability of the calibrator.

Technological Characteristics

Liquid calibrator; buffered human serum matrix; active ingredients: Na+, K+, Cl-. Ready-to-use format. Stability: 2 weeks at 2-8 °C after opening. Designed for use with Roche/Hitachi analyzer ISE modules.

Indications for Use

Indicated for the calibration of Ion Selective Electrodes on Roche/Hitachi analyzers. For prescription use only.

Regulatory Classification

Identification

c. Traceability, Stability, Expected values (controls, calibrators, or methods):

Traceability: ISE Compensator is traceable to the reference material NIST-SRM909b. The reference method is flame photometry for the sodium and potassium analytes and coulometry for the chloride analyte. The value assignment process takes place using multiple external laboratories and using different Hitachi analyzers with ion selective electrodes. The final value assigned to each analyte is lot specific and is found on the Value Sheet that is provided with the product.

Stability: The shelf-life and open-vial stability of ISE Compensator when stored at 2-8°C have been demonstrated using real time stability data and predetermined acceptance criteria.
