^Performance

Introduction

<sup>The MSLDA03 system is based on microfluidics technologies, consists of a portable analyzer and single-use disposable reagent discs. The analyzer contains a variable-speed motor to spin the disc, a photometer to measure analyte concentrations, a thermal line printer to print out results, a capacitive touch screen for communicating with the analyzer. Each reagent disc is self-contained clear plastic disc with a plastic film on top, 7.8cm in diameter and 0.68cm thick, and containing freeze-dried reagent beads in cuvettes around its edge. All of the blood separation and sample diluent mixing are carried out within the disk itself by the centrifugal force generated by the rotation of the motor. The device uses an external scanner or built-in scan module to read the disc information.

To perform the analysis, the operator simply collects a blood sample (lithium-heparinized whole blood or plasma, serum), adds the sample and diluent to the reagent disc, and places the disc into the analyzer drawer in front of the analyzer, and enter patient information. After the analysis is complete, you can choose whether or not to print the report. Results data are also stored in the analyzer's memory and can be transmitted to external printer, computer, memory stick, or laboratory information systems/electronic medical record systems (LIS/EMR).</sup>

 

Setup
Set up the analyzer on a surface as follows:

1. Level and don't put anything in front of the reagent disc drawer.
2. Free of vibration and sudden jolts.
3. Free of hair, dust, and other contaminants.
4. Located in an ambient operating temperature of 10-30 ºC (50-86 ºF).
5. Away from strong sun light and all other potential heat sources.
6. At least six inches (15 cm) from any wall to provide adequate ventilation and access to the power connection and USB ports.

Plug the power jack into the analyzer, then plug the detachable power supply cord into the power adapter and into a grounded electrical outlet.

Caution: To prevent power surges or drain, DO NOT plug the analyzer into the same circuit as a centrifuge or any other high-current device. MSL also recommends using a surge protector of the same type used for computers.



Press the Power button to turn on  the analyzer. During the self-test and the warming period, the display then shows the following.
Note: The analyzer may require additional time for the heaters to warm the analyzer to operating temperature under low ambient temperature.



Sample requirements

1. The MSLDA03 Chemistry Analyzer only accepts lithium-heparinized whole blood, plasma or serum samples.

Note: When collecting the sample in lithium heparin collection tubes, fill the tube at least half-way so the anticoagulant does not become too concentrated in the sample.

1. Only use lithium-heparinized plasma or serum for performing tests of lactate dehydrogenase (LDH), and K⁺
2. A sample size of 90 - 120 µl is required.
3. Whole blood must be analyzed within 60 minutes of collection, or separated into plasma or serum.

Note: If not analyzed immediately, plasma or serum can be stored at room temperature for no longer than 5 hours after centrifugation. If storage for more than 5 hours is required, refrigerate the sample in the stoppered tube at 2 - 8 °C (36 - 46 °F) for no longer than 48 hours, or store it at -10°C for up to 5 weeks in a freezer with no self-defrost cycle. Under these conditions, there will be no clinically important changes in most analyte concentrations.
