4.3 TEST ALERTS
4.3.1 Flashing Values and Dashes
When a test value flashes on and off on the display
panel, an asterisk (*) will appear on the printout after
the numerical value. Flashing values indicate that
the result is outside the validated test range of the
parameter. (See Table 4-1).
Dashes on the panel and on the printout mean
that the computed test value is outside the display
range of the instrument, or that a packed cell layer
is too small to measure. In such cases, dashes and
no test value and bar graph point will appear.
Table 4-1 shows out-of-range points for QBC
AccuTubes. With QBC AccuTubes, elevated cell
counts are indicated by the statement OUT OF
RANGE on the printout and by the following
displays:
• High WBC – Display flashes 99.9 (instead of ---)
when total WBC count is over 99.9 × 10 9 /L.
• High Granulocyte Count – Display flashes 99.9
when Granulocyte count is over 99.9 × 10 9 /L.
• High Lymph/Mono Count – Display flashes 99.9
when Lymph/Mono count is over 99.9 × 10 9 /L.
• High Platelet Count – Display flashes 999 when
Platelet count is over 999 × 10 9 /L.
See Appendix A-2 for out-of-range points for other
QBC tube types.
4.3.2 Special HB-MCHC Conditions
No HB and MCHC values will appear if any of the
conditions listed in Table 4-2 occur. In such cases,
the examination of a peripheral blood smear is
recommended to determine the nature of the red
cell abnormality.
