INTRODUCTION

1 . INTRODUCTION

The Sysmex KX-21 is an automatic multi-parameter blood cell counter for in vitro diagnostic use in clinical laboratories.

The KX-21 processes approximately 60 samples an hour and displays on the LCD screen the particle distribution curves of WBC, RBC, and platelets, along with data of 18 parameters, as the analysis results.

Chapter 1 introduces the overview of the instrument, analysis procedure, etc. that we recommend you to read before using the KX-21. The main contents of Chapter 1 are as follows:

Overview of Instrument

INTRODUCTION

2 . OVERVIEW OF INSTRUMENT

The KX-21 performs speedy and accurate analysis of 18 parameters in blood and detects the abnormal samples. To assure easy sorting of abnormal samples in the laboratory, the instrument displays abnormal analysis data with abnormal marks attached on the LCD screen. Thus displayed analysis data allows detecting those samples which are outside the tolerance and need further analysis and reconsideration.

The KX-21 employs three detector blocks and two kinds of reagents for blood analysis. The WBC count is measured by the WBC detector block using the DC detection method. The RBC count and platelets are taken by the RBC detector block, also using the DC detection method. The HGB detector block measures the hemoglobin concentration using the noncyanide hemoglobin method.
