z If you do not need the PLT, MCV and WBC differential results, you can store
the samples in a refrigerator (2℃ - 8℃) for 24 hours. You need to warm the
refrigerated samples at room temperature for at least 30 minutes before
running them.
z Be sure to mix any sample that has been prepared for a while before running
it.
z Be sure to keep dust from the prepared diluent.
z After mixing the capillary sample with the diluent, be sure to wait 3 minutes
before running the sample. Be sure to run the prediluted samples within 30
minutes after the mixing.
z Be sure to evaluate predilute stability based on your laboratory’s sample
population and sample collection techniques or methods.
z Be sure to select proper reference range as instructed in Chapter 5.5
before running the samples. Otherwise, the obtained results may be
erroneously flagged.
z When switching from the predilute mode to the whole blood mode, the
analyzer will automatically wash the fluidic system.
z After entering all the desired information, you may press [F4] on the external
keyboard to save the changes and exit to the “Count” screen.
z If you intend to do the background check instead of a patient sample,
ENTER “0” into the “ID” box.
z Be sure to keep the sample probe tip away from the tube bottom, otherwise
the aspiration volume may be inaccurate.
z If the analyzer detects WBC/RBC clogging or bubbles during the analysis,
the corresponding error messages will be displayed in the upper left corner
of the screen and the results of all the related parameters will be invalidated.
See Chapter 11 Troubleshooting Your Analyzer for solutions.
z If the ambient temperature is outside the specified operating range, the
analyzer will alarm you for abnormal ambient temperature and the analysis
results may be unreliable. See Chapter 11 Troubleshooting Your Analyzer for
solutions.
z The result of the background check will not be flagged.
z If the PLT value is less than 100 × 10
9
/ L, it is recommended the result be
verified by a microscope.
z To ensure the stability of the analyzer and the acuuracy of the results, be
sure to do the Shutdwon procedure if your analyzer has been working for 24
consecutive hours.
z After entering all the desired information, you may press [F4] on the external
keyboard to save the changes and exit to the “Sample (or Search) Histogram
