Troubleshooting
E106
HbA
1c
Sample
Error - low total
hemoglobin
The mean transmittance
of the hemoglobin
readings is too high.
Possible causes:
• no or low blood
reaction
• no capillary holder
was inserted
• improper constitution
of controls or use of
non-DCA controls
• hemoglobin < 7 g/dL
= anemic patient
• buffer tab is not
removed
1. Discard the sample.
2. Acknowledge the error.
The system is ready.
NOTE: Wait no more than 5
minutes after filling the capillary to
start the test.
3. Repeat the test with a new
sample.
E107
HbA
1c
Sample
Error - high
total
hemoglobin
The mean transmittance
of the hemoglobin
readings is too low.
Possible causes:
• excess blood on
capillary
• irregularity in patient
red blood cells (rare)
• hemoglobin
> 24 g/dL = patient
has abnormally high
hemoglobin
1. Discard the sample.
2. Acknowledge the error.
The system is ready.
3. Repeat the test with a new
sample.
4. Verify that the capillary has no
excess blood on the capillary
holder.
5. If the error still occurs, contact
your local technical support.
E108
HbA
1c
Cartridge Error
- high variable
in hemoglobin
measurement
The %CV of the
transmittance of the
hemoglobin readings too
large. (Particulate
contamination.)
1. Discard the sample.
2. Acknowledge the error.
The system is ready.
3. Repeat the test with a new
sample.
4. If the error still occurs, contact
