CYCLING SAMPLES IN THE PREDILUTE MODE

CYCLING SAMPLES IN THE PREDILUTE MODE
Use the Predilute mode to do a repeat analysis of microcollection samples when less than
125 µL of sample remains. Only CBC results are reported on a Predilute mode sample.
The Predilute mode requires a 1:3 (X3) dilution. The HmX Hematology Analyzer
automatically calculates the correct results based on a times three dilution.
You cannot use the Predilute mode to determine overrange counts that were reported +++++.
To determine overrange counts, make the appropriate dilution, cycle in the Secondary mode,
then multiply the results by the dilution factor.
IMPORTANT
1. Poor quality specimens may require inspection and special attention. Specimens that may contain fibrin,
cell fragments or other debris, or have been difficult to collect, such as, pediatric or oncology specimens
may require special handling.
2. The HmX Hematology Analyzer is an automated cell counter that uses triplicate counting with strict
voting criteria, and has proprietary flagging algorithms to confirm parameter results prior to reporting.
Rarely, a transient or partial aperture blockage may not be detected by any of these processes. A partial
aperture blockage may cause erroneous results, such as, WBC count lower than what is actually present.
3. As with any analysis method in which a specimen of suspect quality is used, particular attention should
be given to the results. Verify the accuracy of results that are flagged and review all results that exceed
your laboratory's action limits.
