the warning.
Blanks must be run every 12 hours, after a Soak Cleaning has been performed, after a
reagent pack change, and after the instrument has been restarted. It is not necessary
to run blanks on days that samples are not run. Additionally, blanks need to be run after
self tests and Deep Cleaning.

Running Samples
Before running a patient sample, take
a few seconds to visually inspect the
sample for clots.
Hold the test tube at eye level and
slowly invert the tube. If a clot
is found, the sample should be
discarded and a new sample should
be drawn.
Even small sized clots will affect the
patient results and could damage
your HM5.

Controls should be run when reagent packs are changed, after a Soak Cleaning has been
performed, and to check the calibration of the analyzer when results are in question.
Remove the control from the refrigerator and allow to warm to room temperature for
15 minutes before use. Mix control tubes thoroughly immediately prior to use. Roll 10X
between hands before gently inverting 10-15X.
Controls should be discarded if expired or if they have been open for more than 14 days.
Running Controls

7. From the New QC Lot screen, select the method
for entering the control target and ranges:
• Enter Manually allows the user to type
in the target and range values from the
control package insert sheet.
• Load from USB Drive allows the user to
upload the values downloaded onto a
USB drive from http://www.abaxis.com/
veterinary/products/vetscan-hm5
• Scan Barcode allows the user to scan
the barcode on the control package
insert sheet using a 2D barcode scanner
to upload the values.

Calibration should be performed when the quality control runs are showing values
consistently out of range and it has been determined that the analyzer is not in need
of cleaning and the quality control material itself is not degraded. Use only the Abaxis
Normal HM5 Control for calibration. Allow the control to come to room temperature by
setting it on the counter for 15 minutes before use. Do not calibrate with controls that are
expired or have been open for more than 14 days.

was difficult. Run Soak Cleaning if error continues.
LPlatelet 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.
WLarge Platelet
