SAMPLE ANALYSIS
MODES OF OPERATION
Sample Modes (Diluter Aspiration)
Sample mode determines which Diluter aspiration method is used.
Primary Mode
• Closed vial
• Automated
• Requires 250 µL of whole blood for a complete CBC or CBC with WBC differential. There must
be a minimum of 1 mL of sample with the proper proportion of blood to anticoagulant in the
tube.
Secondary Mode
• Open vial
• Requires only 150 µL of whole blood for a complete CBC or CBC with WBC differential.
• Use for samples with very low hemoglobin results when Primary mode run produces a partial |
aspiration. (Blood detectors do not recognize these samples as blood.) |
• Use for Reticulocyte samples. Aspirates approximately 2 mL of prepared Retic sample. 50 µL of
whole blood required to prepare the sample.
• Use for LATRON control and primer, with specific Diluter functions per Test mode.
Test Modes (Analyzer Configurations)
Test mode, set at the Analyzer CRT, determines how the data is processed by the STKS.
CBC Mode
Performs basic CBC on whole-blood samples, in either Primary or Secondary mode.
