## Indications for Use

The reagents are intended for use on equivalent Corning Electrolyte Instruments to calibrate the electrodes and flush the sample flow path. Corning is the original equipment manufacturer (OEM) of the instruments and the predicate reagents which are necessary for the continued operation and use of the instruments. The Mission reagents are intended to serve as direct replacements to like named products manufactured by Corning. The OEM products were originally released under the Corning name.

## Device Story

Mission Diagnostic Calibrating Reagents are aqueous salt-based solutions designed as direct replacements for Corning OEM reagents. Used in clinical laboratory settings on Corning 6X4 series electrolyte analyzers; reagents calibrate ion-selective electrodes (ISE) and flush sample flow paths. Operation involves loading reagents into the analyzer; the instrument uses these to establish calibration curves for analytes (Na+, K+, Cl-, Ca++, Li+). Healthcare providers use the resulting analyzer output to measure electrolyte concentrations in human serum samples. The device ensures continued instrument functionality and measurement accuracy, supporting clinical decision-making regarding patient electrolyte balance.

## Clinical Evidence

Bench testing only. Precision data collected over minimum 7 days using three levels of QC material on Corning 614, 644, and 654 analyzers; %CVs ranged from 0.40% to 8.89%. Correlation studies performed on human serum samples (spiked with LiCl and analytes) comparing Mission-calibrated analyzers to Corning-calibrated analyzers. Linear regression analysis (Y=mX+b) showed slopes between 0.96 and 1.07 and R2 values ≥ 0.99 for Na, K, Cl, and Li, demonstrating performance equivalence.

## Technological Characteristics

Aqueous reagents containing salts for analyte calibration and system rinsing. Designed for use with Corning 6X4 series electrolyte analyzers. No specific materials of construction or software algorithms described; device functions as a chemical calibrator for ISE-based diagnostic systems.

## Regulatory 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.

# Correlation with Corning Reagents

Correlation data were obtained from human serum samples for Na, K, Cl, Ca, and Li.

- Serum was first spiked with LiCI to obtain a base Li concentration. .
	- Samples were then spiked to yield varying concentrations of each of the measuring o analytes.
- . Not all runs were specific for all analytes.
- Serum samples were measured each test day on Corning analyzers calibrated with . Mission reagents for 1 run then measured in a comparative run on Corning analyzers calibrated with Corning reagents.

Linear regression analysis was performed using Mission data as the independent X variable and Corning as the dependent Y variable in the equation Y = mX +b

{6}------------------------------------------------

Page 2 -

This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market.

If you desire specific advice for your device on our labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4588. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Compliance at (301) 594-4639. Also, please note the regulation entitled, "Misbranding by reference to premarket notification" (21CFR 807.97).
