## Indications for Use

The Audit™ MicroCV™ D-Dimer Linearity Set is a quantitative, assayed quality control material consisting of five levels of D-dimer analyte. The five D-dimer levels demonstrate a linear relationship to each other for D-dimer analyte. The Audit™ MicroCV™ D-Dimer Linearity Set is intended to use with the Biomerieux miniVIDAS® analyzer and VIDAS® D-dimer assay to verify the calibration of the measuring range. Audit™ MicroCV™ D-Dimer Linearity Set is "For In Vitro Diagnostic Use Only."

## Device Story

Audit™ MicroCV™ D-Dimer Linearity Set is a human-based, lyophilized, five-level quality control material; contains D-Dimer complex. Used in clinical laboratory settings to verify calibration, linear operating range, and reportable range of Biomerieux miniVIDAS® analyzer and VIDAS® D-dimer assay. Levels A through E are related by linear dilution; Level A represents the lower limit and Level E represents the upper limit of the instrument's measuring range. Healthcare providers use the output to confirm instrument performance and ensure accuracy of patient D-Dimer test results. Benefits include improved confidence in diagnostic accuracy for coagulation testing.

## Clinical Evidence

I. Device Description:
The Audit™ MicroCV™ D-Dimer Linearity Set is a human based, lyophilized, five level set of QC material, A, B, C, D, and E. Each level contains D-dimer complex. It is used to confirm the proper calibration of the measuring range of D-dimer on the miniVIDAS® analyzer. Level A D-dimer is near the lower limit level and level E D-dimer is near the upper limit of the measuring range. Levels B, C, and D are related by linear dilution of level A and level E. The target ranges for five levels are:

## K. Standard/Guidance Document Referenced (if applicable):

CLSI EP06-A: Evaluation of Linearity of Quantitative Measurement Procedures: A Statistical Approach.

## L. Test Principle:

The Audit™ MicroCV™ D-Dimer Linearity Set is used to verify the calibration of the D-dimer measuring range of the miniVIDAS® analyzer.

## M. Performance Characteristics:

1. Analytical performance:
a. Precision/Reproducibility:

{2}

For each level of D-Dimer Linearity Set, 15 replicates were tested on the miniVIDAS® on three lots. All levels resulted &lt;10% CV.

b. Linearity/assay reportable range:
Linearity was determined using three lots of the D-Dimer Linearity Set. The mean D-dimer concentration of each of the 5 levels was plotted vs. five assigned levels of concentration. A linear regression value was obtained for each lot, and all results were within the limit of acceptance r² &gt; 0.95.

c. Traceability, Stability, Expected values (controls, calibrators, or methods):
- Traceability: All reagent components are obtained from commercial vendors.
- Open vial stability: A 2-day open vial stability claim was verified using three lots of the Audit™ MicroCV™ D-Dimer Linearity Set. All 5 levels were tested on day zero and day 2. The percent recovery is determined in comparison to day zero values. The percent recovery is within ±10% limit of acceptance.
- Closed vial stability: An accelerated stability is used to predict shelf life. The vials are stressed at 25°C for 64 days to predict two-year stability when stored at 2-8°C. The percent recovery of all levels is determined in comparison to day zero values and the product is considered stable when the recovered values are within ±10%. Real time studies are ongoing to support the shelf life of the product.
- Value assignment: For each level of D-Dimer Linearity Set, 15 separate vials were tested on one miniVIDAS® analyzer yielding 15 measurements. The mean of each level was used to calculate the target concentration. The target range of each level was calculated as ±1SD of the target concentration.
