3M™ Rapid Detection Reader

Introduction

Introduction

Overview

The 3M Rapid Detection Reader is a rapid immunochromatographic system for performing in vitro diagnostic analyses.

The 3M Rapid Detection Reader is comprised of the 3M Rapid Detection Control Module (CM) and the 3M Rapid Detection Test Module (TM). Each Test Module has two ports. Up to three Test Modules are connected to each Control Module providing the user the ability to test 1-6 samples simultaneously. The configuration software and USB flash provided drive allow the user to customize the Reader and maintain the test data. The optional barcode scanner and printer provide ease and accuracy for data entry and record keeping.

Calibration and expiration information for Test Cartridges are input to the 3M Rapid Detection Control Module (CM) through Lot Cards enclosed with the Test Kits.

To perform an assay, the operator places a sample into the well of a Test Cartridge and inserts the Test Cartridge into the 3M Rapid Detection Test Module (TM).

Once the Test Cartridge has been inserted, no further intervention is required. A barcode on the bottom of the Test Cartridge is read to determine the Test Kit lot number. Information loaded with the Lot Card identifies lot specific parameters and expiration date. This ensures that an expired cartridge is not used.

Analysis time is analyte specific and typically less than 20 minutes per sample. Results may be viewed on the 3M Rapid Detection Reader display screen and/or output to the USB flash drive, a printer, or network.

The 3M Rapid Detection Reader only accepts Test Cartridges specified for use with 3M Rapid Detection Test Kits.

The 3M Rapid Detection Reader can operate in either local or network mode. Operator input is accepted from the touch screen or an optional barcode scanner. Stored data including results can be transferred via USB flash drive or sent to a printer or network file.

Intended Use

The 3M Rapid Detection Reader is a general use fluorometer that analyzes results produced by immunoassays specified by 3M.

Full operation requires the use of 3M RAPID DETECTION Test Kit. Optional accessories include a printer and barcode scanner.

Running Quality Control

Running Quality Control

Two types of quality control test records are stored by the 3M Rapid Detection Reader:

LQC (Liquid Quality Control) - external surrogate sample test results.

IQC (Internal Quality Control) - self-diagnostic test results including a check of the power supply voltage, system memory, cartridge transport system, cartridge barcode sensor, LED function, and incubator function for heated assays.

Running LQC

1.From the Main Menu screen (Figure 4) touch LQC. The LQC – Assay List screen will open (Figure 9). This screen will display the entire list of assays sorted in ascending order by the Time to Expiry before assay lockout as displayed in the LQC Expiration column. If LQC is due, this column will display “Run x of y levels” where x is the number of levels required and y is the number of defined LQC levels for that assay. Both the number of levels required and the available defined levels are set using the RCU.

The LQC status column shows the requirements for any LQC levels that have failed. If any LQC fails, that specific control level must be run successfully prior to proceeding with a patient’s test. If the maximum number of Failures before LQC Lockout is reached, this column will display “LQC Lockout”.

NOTE: The assay list is defined in RCU. Any new assays added in the RCU or through the CM will default to LQC disabled and will be listed with N/A in the LQC Expiration column. Refer to the RCU Help Manual for further instruction.

LQC has expired for one or more assays. If icon is displayed, the Assay Status Warnings screen (Figure 11) will display upon touching the Run Assay button. Touch Continue if the desired assay is not listed.

A limited number of overrides can be configured via the RCU. If overrides are available, touch Continue to override lock out (i.e., perform a patient test after LQC is due). The decision to use an Override will be confirmed (Figure 12). Once all overrides have been used, LQC must be performed prior to any further patient testing. If an assay with no overrides is inserted into the TM, an LQC Overdue, Assay Locked warning will display and the assay will be aborted.

Figure 11. Assay Status Warnings

Figure 12. Override Confirmation

NOTE: These warnings are display only and are not selectable. To determine the assay(s) for which LQC is due, view the LQC – Assay List (Figure 9).

NOTE: If there is more than one level of LQC defined for an assay, and LQC has expired for this assay, the LQC timer will be reset to the time at which the earliest LQC level passes in the set. e.g.: Two levels of QC are required, Level 2 passes LQC but Level 1 fails; once Level 1 is repeated and passes, the "Time to Expiry" column in the LQC menu will display the count down from the time when Level 2 passed.
