Access 2 In-Lab Training Manual Page 14 of 119 Version 1.0 (November 2017) Beckman Coulter Technical Product Training

Sample Processing Sequence NOTE: The order of sample and reagent addition is assay specific.

1 The operator places samples into an appropriate rack. Using the Access 2 software (TELL…WAIT…DO…DONE), the operator loads the sample rack onto the Sample Carousel.

2 The operator presses the Run button. The Sample Carousel rotates the rack past the Internal Bar Code Reader and the Cup/Tube Detector while the rack ID is scanned.

3 The Cup/Tube Detector determines if a sample is present. The Internal Bar Code Reader scans the sample IDs. Test orders are matched with each rack position.

4 The sample to be tested (in the Sample Carousel) and the appropriate reagent pack (in the Reagent Carousel) are moved in line with the Main Pipettor Module and the row of reaction vessels (RVs) in the RV Shuttle.

5 The Primary Probe is cleaned using the Ultrasonic Transducer and flushed with wash buffer in the Probe Wash Tower.

6 The Primary Probe moves along the Pipettor Gantry towards the sample and the Ultrasonic Transducer is used for level sensing.

7 The Primary Probe aspirates the assay-specific sample volume then dispenses the sample aliquot into the first RV in the RV Shuttle. The Primary Probe is cleaned at the Probe Wash Tower.

8

The Primary Probe moves to the Reagent Carousel and the Ultrasonic Transducer is used to re-suspend the paramagnetic particles in the reagent pack. The Primary Probe aspirates reagent and dispenses the reagent into the RV containing the sample aliquot. The Primary Probe is cleaned at the Probe Wash Tower.

9 The Primary Probe moves to the Reagent Carousel to aspirate the second reagent (conjugate) and then dispenses the conjugate into the RV containing the sample and paramagnetic particles. The RV contents are mixed by the Ultrasonic Transducer.

10 The Primary Probe is cleaned at the Probe Wash Tower. 11 The RV Shuttle transfers the RV into the Incubator Belt.

12 The RV remains in the Incubator Belt (while the belt moves back and forth) for an assay-specific incubation time during which the antibody-antigen reactions occur.

13 After the incubation time is complete, the RV is transferred to the Wash/Read Carousel.

14

Three washing steps (Wash Arm moves up and down as wash buffer dispense is followed by aspiration in a magnetic field) are performed. These washes remove the unbound material from the RV while retaining material that is bound to the paramagnetic particles. After the last wash, Substrate is added.

15

The contents of the RV are incubated while the RV is moved toward the Luminometer. During this incubation, substrate reacts with alkaline phosphatase bound to the paramagnetic particles to produce light. The Luminometer measures the light in Relative Light Units (RLUs).

16 The RV is transferred from the Wash/Read Carousel back into the Incubator Belt.

17 When the RV aligns with the RV Shuttle, the RV is transferred by the RV Shuttle from the Incubator Belt into the RV Waste Bag (by way of the waste chute).

Assay Technology

Immunoassay is an analytical method that uses antigen-antibody reactions to detect or measure a specific analyte in a sample of body fluid.

The Access 2 uses enzyme-mediated chemiluminescence. Chemiluminescence is a chemical reaction in which one of the end products is

the emission of light. The light emitted is measured in Relative Light Units (RLU).

Step Process

1 Sample and reagent components are aspirated and dispensed by the main pipettor into a reaction vessel (RV). The main pipettor mixes the contents in the RV.

2 The RV is incubated for the required time for the assay.

3 Following incubation, the RV is transferred to the wash/read carousel where it is washed three times in a magnetic field to remove unbound material.

4 Substrate is dispensed into the RV.

5 The RV is incubated to allow the bound analyte complexes to react with the substrate.

6 The light generated by the reaction is read by the Luminometer. The RLU reading is converted to analyte concentration using the calibration curve.

Access 2 Enzyme-Mediated Chemiluminescence Process

Access 2 In-Lab Training Manual Page 16 of 119 Version 1.0 (November 2017) Beckman Coulter Technical Product Training

Assay Technology (continued)

Sandwich Assay

Coated paramagnetic particles bind to an analyte to be measured in a sample. A second reagent (called conjugate) also binds to the analyte. The analyte is bound between the particle on one side and the conjugate on the

other (like a sandwich). The conjugate has alkaline phosphatase bound to it. This enzymatically triggers

the substrate to produce a glowing light. The Relative Light Units (RLUs) produced are directly proportional to the

amount of analyte in the sample (the more RLUs, the higher the analyte concentration).

The system uses a calibration curve to convert the measured light emission to an analyte concentration.

Access 2 In-Lab Training Manual Page 17 of 119 Version 1.0 (November 2017) Beckman Coulter Technical Product Training

Assay Technology (continued)

Competitive Binding Assays

Coated paramagnetic particles bind to an analyte to be measured in a sample. A second reagent (called conjugate) also binds to the coated paramagnetic

particles (the enzyme labeled conjugate is the same analyte as the analyte being measured).

The analyte from the sample and the conjugate compete for binding sites on the coated paramagnetic particles.

The conjugate has alkaline phosphatase bound to it, this enzymatically triggers the substrate to produce a glowing light.

The Relative Light Units (RLUs) produced are inversely proportional to the amount of analyte in the sample (the more RLUs, the lower the analyte concentration).

The system uses a calibration curve to convert the measured light emission to an analyte concentration.

Sample Racks and Containers

To accommodate different sizes of validated sample containers, there are three different rack sizes: 13 mm, 16 mm and 16 mm elevated.

The instrument identifies the sample container in use based on the Rack ID bar code.

Each rack accommodates only one type of sample container. The operator identifies the rack based on the Rack ID bar code and the colored

Rack Icon. All sample containers must be uncapped prior to processing. All sample containers must be seated all the way down into the rack. Assay pickup volumes can be found in the Assay Summary Tables or the

Consumable IFU/CIS/Setting Sheets located on the Beckman Coulter website. The following tables list all of the containers that are currently validated for use

on the Access 2 instrument along with the corresponding rack ID range and the dead volume for each container.

Dead Volume is the amount of sample that must be present to allow the primary probe to accurately pick up the sample aliquot.

Data Management

______________________________________________________________________ Introduction The Access 2 creates and stores data for every test sample the system runs. Test samples include: patient samples, quality control samples and calibration sample sets as well as some maintenance samples. In this chapter you will learn how to search, review and print test sample data. It is important to review the results for calibration and QC before processing samples. Patient samples should be reviewed for any flags before releasing results. This chapter will cover the following:

Calibrator setup. Reviewing calibration status. Setting up quality controls. Reviewing QC charts and data. Reviewing patient results. Printing test result reports. Applying filters to define the displayed patient data.

The system can be setup to automatically print calibration and patient results. You can also print or reprint reports as needed. NOTE: Where you review and manage QC and patient test results will be determined by your laboratory policies and procedures. ______________________________________________________________________ Practice Configure a calibrator. Use the information presented in the following pages to navigate to the Calibration

Data screen to review and print a calibration report. Setup a quality control. Review Quality Control data and print a Quality Control report. Review patient results and print a report. Apply a filter to the Test Results screen.

Reviewing Quality Control Data Quality controls (QC) are samples of known reactivity. You run quality controls along with patients to monitor your system performance. The system performs quality control calculations by comparing the results to the acceptable range of expected values you have entered into the system in the QC setup screen for each analyte you want to monitor. Westgard rules (see the table below) can be applied to the collected QC data to decrease subjectivity of data analysis and flag results when rules are broken. QC data is displayed graphically as Levey-Jennings charts and numerically in a data grid. Graphs and grid data can be viewed and printed separately or together. You may omit points from the calculations and add comments to points to explain why they were omitted or other information about a point you wish to document. To get to the Quality Control screen from the Main Menu, select Quality Control F4 or select the QC status button from any screen. The calculated QC values tracked by the system are:

The mean (average) test result value. The standard deviation (SD) from the mean. The percent coefficient of variation (%CV).

Westgard Rules

Rule Interpretation

1 - 2s The system marks a data point if it is more than 2 SD from the mean.

2 - 2s The system marks a data point if two consecutive points of a given quality control are more than 2 SD from the mean. The system only marks the second point.

1 - 3s The system marks a data point if it is more than 3 SD from the mean.

4 - 1s The system marks a data point if four consecutive points of a given quality control are more than 1 SD from the mean in the same direction. The system only marks the fourth point.

10x The system marks a point if ten consecutive points of a given control are on the same side of the mean. The system only marks the tenth point.
