2.5 Normal Measurement
In normal measurement, multiple samples are continuously measured using the sample racks.
2.5.1 Preparing Samples
Prepare: Protective gloves, sample containers, port guides and sample racks
For other required items, see “ Items required for normal measurement” on page 2-17.
Wear protective gloves to prevent exposure to pathogenic microbes.
Discard liquid waste, used samples and protective gloves in accordance with local
regulations for biohazardous waste.
NOTE:
Perform HbA1c calibration before the instrument is used for the first time after installation (see “2.8. HbA1c
Calibration” on page 2-38).
IMPORTANT:
Samples without plasma cannot be measured as-is. Dilute samples from which plasma has been removed
with DILUENT 90 and measure as hemolysis samples. Measuring samples without plasma in a whole blood
sample rack will cause inaccurate measurement results.
Use suitable sample racks. The following may occur if the wrong sample rack is used:
• Accurate measurement results may not be obtained.
• Measuring whole blood sample with the hemolysis pair rack or hemolysis control rack may seriously
degrade the column. If whole blood is measured with these racks, it is recommended to replace the
column with a new one.
• If a sample tube with a barcode label is mistakenly set in the whole blood pair rack instead of a normal
rack, the measurement results of other samples are reported for the IDs of samples in odd-numbered
ports.
In the Variant mode, measuring samples that contain variant Hb other than HbS and HbC may cause higher
or lower HbA1c measurement values.
In the Fast mode, measuring samples that contain variant Hb may cause higher or lower HbA1c
measurement values.
