3.7.7 Testing HbA1C Reproducibility (Hemolysis Sample)
Run a reproducibility test following the instructions described below if the reproducibility of HbA1C measurement
results seems to have been reduced in hemolysis sample measurements. This test repeatedly measures the same
hemolysis sample or hemolysis control divided into multiple sample containers, and displays statistical information
(average, R, S.D. and C.V.) from those results.
Prepare: Hemolysis sample or hemolysis control (1 type), sample containers (sample tube or sample cup, quantity
needed for the number of measurements), hemolysis control rack and protective gloves
1 Prepare samples.
a On the standby screen, check whether the measurement mode is set to the mode you want to test.
• To change the mode, see “2.4. Measurement Mode Selection (Variant or Fast)” on page 2-14.
b On the standby screen, select , <8 Instrument diagnosis menu>, <5 HbA1c reproducibility test menu> and
<2 Hemolysis sample measurement> in that order.
• The message “Load samples onto sampler.” will appear.
c Prepare sample in a sample tube or sample cup.
• Divide the same hemolysis sample (or hemolysis control) into the
sample containers.
• You can place up to 5 sample tubes or sample cups.
d Set the sample containers in the hemolysis control rack.
• For sample tubes of a 15 mm diameter, remove the spinning unit
adapters before setting the tubes.
For sample tubes:
Odd-numbered ports: Sample tube
Even-numbered ports: Empty
Wear protective gloves to prevent exposure to pathogenic microbes.
Discard used samples and protective gloves in accordance with local regulations for
biohazardous waste.
Number of measurements:
You can place up to 5 sample containers with hemolysis samples in the hemolysis control rack and up to 3
measurements can be performed per sample container. So, a maximum of 15 measurements can be performed
at a time in the reproducibility test (see “Control measurement count” in “3.3.5. Setting the HbA1
C Measurement
Conditions” on page 3-14).
