after collection.
If you do not need the PLT, MCV and WBC differential results, you can store
the samples in a refrigerator (2℃ to 8℃) for 24 hours. You need to warm the
refrigerated samples at room temperature for at least 30 minutes before
running them.
Mix any sample that has been prepared for a while before running it.
Keep dust from the prepared diluent.
After mixing the capillary sample with the diluent, wait 5 minutes before
running the sample.
Run the prediluted samples within 30 minutes after the mixing.
Evaluate predilute stability based on your laboratory's sample population
and sample collection techniques or methods.
If you intend to do the background check instead of a patient sample, enter
"0" into the "ID" box.
Keep the sample probe tip away from the tube bottom; otherwise the
aspiration volume may be inaccurate.
When the aspiration is done, remove the sample tube only when the sample
probe is out of the tube.
If the analyzer detects WBC/RBC clogging or bubbles during the analysis,
the corresponding error messages will be displayed in the error message
area and the results of all the related parameters will be invalidated. See
Chapter 11 Troubleshooting Your Analyzer for solutions.
The result of the background check will not be flagged.
Select proper reference range as instructed in Chapter 5.3.6 before running
the samples. Otherwise, the obtained results may be erroneously flagged.
To ensure stable analyzer performance and accurate analysis results,
perform the "Shutdown" procedure to shut down the analyzer after it has
been running continuously for 24 hours.
Shut down the analyzer strictly as instructed below.
Fur and skin debris may block the aperture. Keep the sample clean before
using the analyzer to analyze it.
Use the specified controls. Using controls other than the specified will lead
to misleading results.
Refer to the instructions of use of the controls for how to store and use the
controls.
Calibrate your analyzer before trying to establish the expected results by
calculating the averages of random patient samples.
Refer to the instructions of use of the control for information on the lot
