H : located next to a result of a parameter shows that the value is above the upper limit set up by
the operator.
L : located next to a result of a parameter shows that the value is below the lower limit set up by
the operator.
With the print-out of results the following general flags may occur :
*
following either WBC, RBC, HCT or PLT indicates that the system, analyzed the sample three
times but that all three counts differed and were outside the systems precision limits. The result
should be verified by repeating the sample or checked according to one of the laboratory reference
methods.
$
following a parameter : indicates that the instrument performed 3 counts, 2 of the 3 counts are
within :
- 7% for WBC
- 5% for RBC
- 15% for PLT
If the maximum of the first two raw counts is lower than :
- 3000 for WBC, the limit becomes 9%
- 16000 for RBC, the limit becomes 8%
- 400 for PLT, the limit becomes 20%
Result for the concerned parameter can be accepted.
--- D
If results exceed the linearity limits shown below, a < D > will be printed after the result. If
the results greatly exceed the limits, a result will not be shown on the LCD or the printout. The flag
DIL will be shown on the LCD, and ---D or ---0 will be printed and transmitted to the LIS.
Repeat the sample using a 1:2 dilution and repeat each time the flag reappears.
Limits to the linearity ranges : - WBC > 100 x 10 3 /mm 3
- RBC > 8.0 x 10 6 /mm 3

4.3. STUDY OF GENERAL FLAGS
NOTE: Dilute the sample using autologous plasma or Saline.
Temperature : Operating reagent temperature should be within the recommended
limits (18°C to 32°C, 65°F to 90°F). The operating temperature can be printed out on the
result form. When these limits are exceeded, the values obtained cannot be guaranteed
with certainty and the result transmitted on the RS shows an error code.
NOTE:
