5 – Performance and Limitations
Operating Ranges
Hematology parameters measured with the QBC Star system are valid over the following range of values:
Hematocrit 15 – 65%
Hemoglobin 5.0 – 20.0 g/dL
Mean Corpuscular Hemoglobin Concentration 25 - 37.3 g/d
Platelet Count 20 – 999 x 10 9 /L
White Blood Cell Count 1.6 – 99.9 x 10 9 /L
Granulocyte Count 0.8 – 70.0 x 10 9 /L
Granulocyte % 1 - 99%
Lymph/Mono Count 0.8 – 99.9 x 10 9 /L
Lymph/Mono % 1-99%
results that fall outside these ranges may be confirmed by alternate methods.
Precision
Data on typical within-run precision tests on QBC Star tubes tested in the QBC Star system are shown
in the two tables below. the precision data represents the analysis of eleven whole blood specimens,
each assayed in replicates of 10.
