SAMPLE ANALYSIS
CYCLING SAMPLES IN THE PRIMARY MODE
Valve (BSV). These blood detectors optically sense air bubbles, diluent, and blood. As an
indication of a good aspiration, the system looks for blood in both detectors. If the detectors
optically identify bubbles in the sample, the instrument pierces the tube a second time. If the
second aspiration contains bubbles, the instrument reports a partial aspiration. Bubbles or air
may be present for various reasons, such as short sample aspirations or blockages in the
aspiration pathway. Single dots (
results when a partial aspiration occurs. Samples that generate multiple partial aspiration
messages should be evaluated for specimen quality according to laboratory's protocol.
Samples with very low hemoglobin results may give partial aspirations when run in the
Primary mode because the blood detectors do not recognize the sample as being blood. To
obtain results, cycle the sample in the Secondary mode.

CYCLING SAMPLES IN THE PRIMARY MODE
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.
4. Changing the reporting units after initial setup may cause misleading results. Make sure the reporting
units currently selected for patient results are correct by checking any result in the database.
5. A printer malfunction could cause you to report erroneous results. Check all printers attached to your
HmX Hematology Analyzer. Make sure they are working properly and all numbers are printing correctly.
6. Operating the HmX Hematology Analyzer with open doors or panels introduces electrical interference
which can cause misleading results. Operate the HmX Hematology Analyzer with all doors and panels
closed.
7. Running out of reagent will cause erroneous results. The reagent sensors are designed to alert you
before you run out. If you disable reagent sensors, the message
screen and on graphic printouts. Carefully monitor the reagent's level if you ever disable its sensor.
