E Empty sample Ensure the sampling depth is appropriate for the tube being
used and that the tube is filled at least 1/2 full. If not, redraw a
new sample.
M,N Lyse delivery issue
or very
high WBC count
Check Lyse (yellow) tube for kinks and loose connections at
the bottle cap or dip tube and back of the analyzer and verify
the Lyse line is connected to the correct port on the analyzer
and the correct bottle from the pack. Prime Lyse if bubbles are
present. If a high WBC value is suspected, view manual smear
to confirm high WBC.
c,C,Q Cellular clumping Run 2 automatic self cleanings. Redraw then rerun if the draw
was difficult. Run Soak Cleaning if error continues.
L Platelet clumping,
Lyse resistance or
Macroplatelets
If the patient is a King Charles Cavalier Spaniel or other breed
with known predisposition to macro-platelets, perform a
manual smear for the WBC and PLT. If the draw was difficult,
the platelets are low or there were delay in filling the tube,
redraw and rerun. Check Lyse tube for kinks or bubbles. If no
Lyse issues found and the warning persists, rerun the sample
with an increased Lyse +0.1 or +0.2.
W Large Platelet
clumps in cat
samples
Redraw sample, being sure to immediately transfer the sample
into the tube and invert completely 10-15 times or more.
Y EOS clogging Ensure Lyse 2 (orange line) is connected properly to the back
of the analyzer and to the correct reagent bottle. If connections
are good but bubbles are present, prime Lyse 2 twice and re-run
sample. Run automatic self cleanings and re-run well-mixed sample.
