DESCRIPTION
Have you ever wondered why you get wide variability of test results when a blood sample is tested using different hematology cell counters? This program describes the principles used to produce cell-count results. Instrument performance is discussed in relation to linearity, comparability and proficiency testing comparison so that you will have a better understanding of why the various instruments give different test results for the same measured analyte. The intent is to provide information to aid in the choice of a hematology instrument suitable for your testing requirements.

OBJECTIVES

• Outline the principles of hematology cell counters used to measure direct, derived and calculated analytes
• Explain how different instruments can produce disparate results for the same measured analyte
• Describe the impact of the various cell counters on blood component and apheresis unit measurements

AUDIENCE
Physicians, Technologists, Managers/Supervisors
