# Audit MicroControls Linearity Set for NT-proBNP and Troponin I/II - 5 X 1 mL

This comprehensive 5 X 1 mL linearity set provides essential quality control material for verifying the performance of your PathFast ImmunoAnalyzers. Designed specifically for cardiac marker testing, this set includes five distinct levels of human serum-based material to ensure accurate and reliable results for NT-proBNP and Troponin I/II analysis.

## Professional Laboratory Quality Control

The linearity set serves as a critical tool for laboratory professionals to verify calibration, determine linearity, and confirm reportable ranges for cardiac marker testing. Each vial contains lyophilized material that simulates human patient serum samples, providing consistent and reliable performance across all five levels.

### Five-Level Testing System

The set includes Levels A through E, each demonstrating a precise linear relationship to the others. This multi-level approach allows laboratories to thoroughly assess instrument performance across the entire measurement range, ensuring accurate patient results and maintaining compliance with quality assurance standards.

### Key Applications
*   Linearity determination for cardiac marker assays
*   Calibration verification for PathFast ImmunoAnalyzers
*   Reportable range verification
*   Quality control and instrument performance monitoring

Manufactured in the United States and compliant with both Buy American Act and Trade Agreement Act requirements, this linearity set meets the highest standards for laboratory quality control materials. The lyophilized format ensures stability and extended shelf life, while the human serum-based composition provides realistic testing conditions.
