A-1.4 CALIBRATION DETAILS
Perform the calibration check described in
Section 4 of this manual. Before running patient
samples, daily testing of the Autoread Plus analyzer
calibration check rod is strongly recommended to
verify the performance of the instrument. Calibration
adjustments must be made only by authorized
service personnel.
A-1.5 QUALITY CONTROLS
A-1.5.1 QBC Hematology Tests
Controls and proficiency tests to monitor
performance are described in 4.5.2 and 4.5.3.
Reference methods for QBC hematology tests are
provided below.
Parameter Reference Method
Hematocrit .............Centrifugal Microhematocrit 13
Hemoglobin ...........Cyanmethemoglobin Method 14
WBC ......................Impedance Cell Counter
GRANS .................. 100-Cell Manual Differential Count*
LYMPH/MONO ...... 100-Cell Manual Differential Count**
PLT ........................
Phase Microscopy or Impedance Cell
Counter
MCHC ....................***
* Manual differential count of granulocytes should include the sum
of neutrophils, eosinophils, and basophils for comparison with
the GRANS count of Autoread Plus analyzer.
** Manual differential count should include the sum of lymphocytes
and monocytes for comparison with the LYMPH/MONO count of
Autoread Plus analyzer.
*** MCHC of the Autoread Plus analyzer is a calculated value
derived from the hematocrit and hemoglobin. Comparison
of these latter parameters with the recommended reference
methods will ensure accuracy of MCHC.
