3. Troubleshooting Procedures
3.1. Non Homogeneous Smears
The smears appear:
■ erratic with a rough edge
■ with streaks
■
with a dip in the center of the feathered edge
Cause Solution
Blood is trapped in the front of the spreader
blade.
Do not hold the lever down too long. Release it as soon as it
reaches its bottom position.
Avoid pressing down the lever too rapidly.
Avoid jerking the lever when you remove your finger from it.
Avoid delivering the blood drop off the target location.
Adjust the pause control time if necessary.
Spreader blades are dirty. Clean the blades.
Spreader blades are nicked. Replace the nicked blades.
There are bubbles in the blood drop.
Avoid dispersing the blood drop in such a way that it produces
bubbles. If bubbles are produced, attempt to pop them using
the edge of the pipette or wooden stick.
Slides are dirty. Do not use slides that appear to be particularly dirty or greasy.
The blood drop is dried.
Push the lever immediately down after the blood drop has
been applied to the slide.
3.2. Excessively Long Smears
Cause Solution
The blood drop is too large. Apply a smaller blood drop.
The smear is too thin or the blood has very low
hematocrit level. Rotate the smear control button in 1/8 of a turn anti-clockwise
until a satisfactory setting is obtained.
