Understanding Your Analyzer
2-16
2.5.2 Lyse
The lyse is formulated to meet the following requirements:
To rapidly break down red blood cell walls, release the hemoglobin from the cell, and
reduce the size of cellular debris to a level that does not interfere with white blood cell
counting.
To convert hemoglobin to a complex whose absorbance is determined by the
hemoglobin concentration.
2.5.3 Rinse
The rinse is formulated to rinse the baths and metering tubes and to provide proper meniscus
formation in the metering tubes and maintain it during each measurement cycle.
2.5.4 E-Z Cleanser
The E-Z (enzymatic) cleaner is an enzyme-based isotonic, cleaning solution and wetting
agent formulated to clean the fluidic lines and baths.
2.5.5 Probe Cleanser
The probe cleanser is an alkaline cleaning solution formulated to clean the fluidic lines,
apertures and baths.
2.5.6 Controls and Calibrators
The controls and calibrators are used to verify accurate operation of and calibrate the
analyzer.
The controls are commercially prepared whole-blood products used to verify that the analyzer
is functioning properly. They are available in low, normal, and high levels. Daily use of all
levels verifies the operation of the analyzer and ensures reliable results are obtained. The
calibrators are commercially prepared whole-blood products used to calibrate the analyzer.
Read and follow the instructions for use to use the controls and calibrators. All references
related to controls and calibrators in this manual refer to the controls and calibrators reagents
specifically formulated for this analyzer. You should buy those controls and calibrators from
Mindrayor Mindray-authorized distributors.
