7.4 Quality Control
The HemoCue Hb 201 DM Analyzer has an internal quality control, the self-test. Every time
the Analyzer is turned on, it will automatically verify the performance of the Analyzer. This
test is performed every eighth hour if the Analyzer is left turned on. The result of the
self-test is stored as an EQC (Electronic Quality Control).
Follow local guidelines regarding quality control procedures. If a quality control test is
required by local or other regulations and therefore should be performed, only use Liquid
Controls recommended by HemoCue. See relevant package insert for more information.
7.5 Limitations
For limitations, see HemoCue Hb 201 Microcuvettes package insert.
7.6 Expected values
According to Dacie and Lewis, Practical Haematology:
Children 11.0 - 14.0 g/dL (110 - 140 g/L, 6.8 - 8.7 mmol/L)
Women 12.0 - 15.0 g/dL (120 - 150 g/L, 7.4 - 9.3 mmol/L)
Men 13.0 - 17.0 g/dL (130 - 170 g/L, 8.1 - 10.5 mmol/L)
Children, 2 years to teenage, gradually increase to adult values.
Due to a wide range of conditions (dietary, geographical, etc) which aect normal values, it
is recommended that each laboratory establish its own normal range.
