Sysmex SF-3000 Operator's Manual -- Revised September 1995 8-23
Short Sample
Phenomena This error occurs during auto mode or manual closed mode analysis only.
Sufficient blood sample volume was not aspirated. (Two sensors at SRV
cannot detect the sample blood.)
The sample is not processed, and data is reported by "----" as an analysis
error. The "Check Stored Data" message also appears.
If the system is set to be stopped by this error, the system will be STAT ready
for the sample analysis in manual or capillary mode.
If the system is set to continue analysis when this error occurs, the system
will process the next sample.
Probable Cause 1) Blood volume is insufficient.
2) Piercer needle and/or whole blood aspiration line is dirty.
Corrective Action 1) Check the blood sample volume. If the blood sample volume is short,
analyze it in manual or capillary mode.
2) If the error persists although there is enough sample in the collection
tube, it is suspected that the piercer or the whole blood aspiration line is
dirty.
Clean them as follows:
(a) Perform the shutdown sequence using CELLCLEAN (or 5% filtered
sodium hypochlorite). Refer to
Chapter 5, Section 3.1: Shutdown
.
(b) When the shutdown sequence is complete, press [Auto Rinse] key to
check the background count. When the background check is
complete and system enters Ready, reanalyze the sample.
(c) If the error persists, aliquot CELLCLEAN into 3 collection tubes and
analyze these samples in the auto mode to clean the piercer and the
whole blood aspiration line.
(d) If the error still persists, it is assumed that the piercer is blocked by
clots. Replace the piercer. Refer to
Chapter 5, Section 8.2: Replace
the Piercer
.
NOTE: Sometimes the sample volume cannot be monitored b
the Sampler Unit
because the blood collection tube is dirt
or because the bar code label
has been affixed too low. In such cases, aspiration is performed an
wa
,
and if the volume is insufficient, "Short Sample" or "Sample Not Asp
Error" will occur.
