Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Method Comparison Matrix Comparison Linearity Sensitivity Precision Interference In use (On board) & Calibrator Stability Prozone Sample Dilution
Method comparison and bias estimation experiments were designed using CLSI Guideline EP09-A3 "Measurement Procedure Comparison and Bias Estimation Using Patient Samples; Approved Guideline". These patient correlation studies demonstrate equivalence between the predicate AU5800 and the candidate DxC 700 AU. All method comparisons met the required specifications.
Anticoagulation Studies were designed using CLSI EP09-A3: Measurement Procedure Comparison and Bias Estimation Using Patient Samples: Approved Guideline - Third Edition. All results passed specification.
Analytical range (linearity) studies were designed to meet the requirements of CLSI quidelines EP06-A "Evaluation of the Linearity of Quantitative Measurement Procedures: A Statistical Approach; Approved Guideline". The performance data for the study demonstrates linearity throughout the claimed dynamic range of each assay.
LoB, LoD and LoQ studies were designed primarily from CLSI quideline EP17-A2 "Evaluation of Detection Capability for Clinical Laboratory Measurement Procedures Approved Guideline - Second Edition. The experimental design consisted of replicate measurements on blank and low level samples using 2 lots of reagent across multiple days. A total of 60 blank replicates per reagent lot and 280 low level sample replicates per reagent lot were generated. All representative reagents met specifications and were below the claimed measuring range of the reagent.
Repeatability (within-run) and within-laboratory (total) precision studies were designed from CLSI guideline EP05-A3 "Evaluation of Precision of Quantitative Measurement Procedures; Approved Guideline - Third Edition". The precision was verified on the DxC 700 AU using 1 lot of reagent and 1 lot of calibrator and utilized duplicate sample analysis, twice daily, over the course of 20 days (n=80) for multiple sample levels. All assays met the performance precision specifications.
In-Use and Calibration Stability Verification (EP25-A): This protocol followed CLSI EP25-A quideline "Evaluation of Stability of In Vitro Diagnostic Reagents; Approved Guideline"; The aim was to verify the 30 and 90 day on-board claim for the representative reagents and to verify the 1 day calibration stability claim for the ISEs on the DxC 700 analyzer. All results were within specification.
Interference studies were designed based on CLSI Guideline EP07-A2: "Interference Testing in Clinical Chemistry: Approved Guideline - Second Edition". All interferences met the required specifications on the DxC 700 AU analyzer.
Prozone: Testing was carried out to verify the prozone performance on the DxC 700 AU using CRP Latex (High Sensitivity application) as the representative assay. Testing demonstrates that samples with CRP concentrations up to 750 mg/L will not generate falsely low results within the analytical range.

5.0 Device Description
5.1 ISE Reagents
The ISE module for Na*, K*, and Cl employs crown ether membrane electrodes for sodium and potassium and a molecular oriented PVC membrane for chloride that are specific for each ion of interest in the sample. An electrical potential is developed according to the Nernst Equation for a specific ion. When compared to the Internal Reference Solution, this electrical potential is translated into voltage and then into the ion concentration of the sample.
Reactive Ingredients: ISE Buffer (Triethanolamine), Mid-Standard (Na, K, CI), Reference (Potassium Chloride), High Serum Standard (Na, K, CI), Low Serum Standard (Na, K, CI), High/Low Urine Standard (Na, K, CI), Internal Reference Solution (Potassium Chloride, Silver Chloride), and Na*/K* Selectivity Check Solution (Na, K).
5.2 Glucose
In this Beckman Coulter procedure, glucose is phosphorylated by hexokinase (HK) in the presence of adenosine triphosphate (ATP) and magnesium ions to produce glucose-6-phosphate (G-6-P) and adenosine diphosphate (ADP). Glucose-6-phosphate dehydrogenase (G6P-DH) specifically oxidizes G-6-P to 6-phosphogluconate with the concurrent reduction of nicotinamide adenine dinucleotide (NAD+) to nicotinamide adenine dinucleotide, reduced (NADH).

For the AU400/AU640/AU600 the change in absorbance at 340/380 nm is proportional to the amount of glucose present in the sample. For the AU5800/AU5400/AU2700/AU680/AU480/DxC 700 AU the change in absorbance at 340/660 nm is proportional to the amount of glucose present in the sample.
Reactive Ingredients: PIPES- buffer (pH 7.6), NAD*, Hexokinase, ATP, Mg4*, G6P-DH
5.3 CRP Latex
The CRP Latex reagent is an in vitro diagnostic device that consists of ready to use buffer and latex particles coated with rabbit anti-CRP antibodies. Depending on the application used (different instrument settings), two measuring ranges are available: Normal application (CRP Concentrations ranging between 1.0-480 mg/L) and Highly Sensitive (Cardiac/ Neonatal) Application- (CRP concentrations ranging between 0.2- 80mg/L).
Reactive Ingredients: Glycine buffer, Latex coated with anti-CRP Antibodies.

9.6 In-Use and Calibration Stability Verification (EP25-A):
This protocol followed CLSI EP25-A quideline "Evaluation of Stability of In Vitro Diagnostic Reagents; Approved Guideline"; The aim was to verify the 30 and 90 day on-board claim for the representative reagents and to verify the 1 day calibration stability claim for the ISEs on the DxC 700 analyzer.
Testing was performed using one reagent lot (where appropriate) and one calibrator lot on the DxC 700 analyzer. Calibration (as required) was performed on the initial day of testing and controls were run in duplicate. At each timepoint the reagents were calibrated (if required) and controls were run in duplicate. Controls were run in duplicate on Day 1 + greater than 2hrs for the ISEs. The mean of the control replicates was calculated and the bias of this result to the mean of the control on Day 0 was calculated. The final time-points exceeded the claims on the reagent and ISE IFUs. For the reagents, linearity was assessed at the final time point.
A summary of in-use and calibration stability specifications and results are detailed in the tables below. All results were within specification and provide data to support the on-board and calibrations stability claims in the reagent and ISE IFUs.

The logo consists of a red circle with two white curved lines inside, followed by the words "BECKMAN" in bold black letters on the first line and "COULTER" in bold black letters on the second line. The logo is simple and modern, and the use of red and black gives it a strong and professional look.
9.7 Interferences (Analytical specificity):
Interference studies were designed based on CLSI Guideline EP07-A2: "Interference Testing in Clinical Chemistry: Approved Guideline - Second Edition".
All test samples were assayed in quadruplicate at two analyte levels. The sample pools tested were at different levels of interferents to determine the magnitude of their effect (if any). The data analysis involved calculating the difference in recovery of the samples with and without the potential interfering substances. The results are summarized below. All interferences met the required specifications on the DxC 700 AU analyzer.

intf. 750 mg/L. The CRP concentration was verified using three replicates of three dilutions within the measuring range. Eleven dilutions of the high prozone pool were then prepared and ran n=3 to confirm prozone performance. Testing demonstrates that samples with CRP concentrations up to 750 mg/L will not generate falsely low results within the analytical range. |
