How to Run a QC
Woodley Equipment Company recommends a Quality Control (QC) should be analysed on the InSight V3 Plus at the start of each working day.
Why Run a QC?
- To assess the quality and performance of the practice laboratory.
- To ensure that results generated by the InSight V3 Plus are correct.
- QC monitors staff, equipment, reagents and result reporting.
Running a QC
- Navigate to QC test screen by selecting ‘QC’
- Ensure the correct file number for the current lot of QC is selected
- Ensure that the QC has been stored correctly, is in date and check that the vial lot number and expiry date correspond to those on screen. If a new batch, enter the new QC reference ranges.
- Thoroughly mix blood by slowly inverting tube 10 times. DO NOT use a rotary mixer. Make sure the sample is warmed to room temperature.
- REMOVE SAMPLE CAP and place QC sample under the probe
- Press back plate to start analysis
- Results will automatically display once analysis is complete
- Check that the QC is within the ranges
- Sign the QC log sheet under the appropriate date and return QC to the fridge
NOTE: Keep QC vials refrigerated and allow at least 15 minutes to reach room temperature (18-30oC) before use. After sampling wipe the threads of both vial and cap with a lint free tissue. Replace cap and return to refrigerator for maximum open vial stability which is up to 14-28 days if stored at 2-8oC.
In the event of a QC failure
- Reprocess the sample
- If it is still out of limits, repeat with a fresh QC
- Contact your Woodley Sales Representative or Woodley Equipment Company Technical Support on +44 (0)1204 669033 and press option 1.

WBC Alarm for abnormal histogram:
-
R1
indicates there is an abnormality in the left side of LY wave peak, which is probably caused by incomplete haemolysis of RBC, platelet clump, giant platelet, nucleated RBC, abnormal lymphocyte, proteinic, fat granule, or electrical noise. Review a blood film. -
R2
indicates there is an abnormality in the area between LY wave peak and MO wave, which is probably caused by pathologic lymphocyte, atypical lymphocyte, an increase in original cell, eosinophilia or basophilia. Review a blood film -
R3
indicates there is an abnormality in the area between MO wave and GR wave peak, which is probably caused by immature granulocyte, abnormal cell subpopulation or eosinophilia. Review a blood film -
R4
indicates there is an abnormality in the right side of GR wave peak, which is probably caused by an increase in granulocytes.
?EOS
Indicates that there is an increase in eosinophils, review a blood film.
PLT Abnormal histogram:
- PM
indicates there is a defined boundary between PLT and RBC, which probably caused by the pre sense of giant platelet, platelet clump, small RBC, cell debris or fibrin. Review a blood film

Haematology Sample Handling
Your InSight V3 Plus hematology analyzer can only produce results as good as the sample provided. Sample handling can be the limiting factor in producing accurate results. Check QC’s regularly, if results are within range then any aberrant results often indicate improper sample handling.
-
Venipuncture: A quick non-traumatic venipuncture is critical. Use a 22 gauge needle or larger to minimize the likelihood of cell damage
(haemolysis) and formation of clots. Avoid repositioning of the needle and/or excessive suction on the syringe. Fractious cats are likely to have platelet aggregates. If in doubt consult a blood film. -
Sample transfer: Immediately transfer the blood sample into an EDTA tube. Remove needle and slowly express the sample down the side of the tube to prevent haemolysis and clots. DO NOT use heparin tubes.
-
Sample volume: Fill the tube adequately (at least ½ full). Under filled blood tubes (incorrect ratio EDTA: Blood) will increase the EDTA concentration and can cause cell shrinkage leading to falsely decreased MCV and HCT.
-
Sample mixing: Thoroughly mix sample either on a mixer or 8-10 inversions by hand up until placing the tube under the sample probe (especially horses). Check the tube for clots prior to sampling, DO NOT test a clotted sample- take a repeat sample.
-
Time delay: Blood samples should be processed as soon as possible after collection. Platelets are affected by time delay as they have a short half-life and can clump even in the presence of an anti-coagulant. Platelet counts performed after 4-6 hours should be considered suspect. Prolonged sample storage before processing especially when not refrigerated can lead to swelling of the RBC leading to a falsely elevated MCV. If there is a time delay between sample collection and testing store the sample 2-8oC. Excessive temperature can lead to cell autolysis (self breakdown).
How to Perform a Clean
A clean should be performed daily or when the background results exceed the
range, bad differential and if a clot remains in the system following other
maintenance procedures. The analyzer will prompt when the Clean is due. You
may also be instructed to perform this by your Woodley Equipment
Representative or by Woodley Equipment Technical Support when troubleshooting.
- Select ‘Setup’
- Maintenance- Rinsing Cups.
- Select ‘Yes’ to perform Clean
- Present the Cleanser under the sample probe and press ‘Aspirate’
- The clean will take 10minutes
Interpreting Blood Cell Histograms
Histograms demonstrate the distribution of blood cell populations providing a
graphic representation of cell size versus cell number. As cells pass through
the aperture the different sized pulses generated by impedance changes are
sorted and stored in the analyser memory. The memory creates a volumetric
distribution histogram for each blood cell population (red blood cells, white
blood cells and platelets). Histograms give a visual representation of cell
size and number and although not considered to be diagnostic for any
particular condition, they can be used to identify abnormal cell populations
or sampling problems. They also work as a quality check when flags are
produced to provide a useful tool to determine if further investigations, such
as the viewing of a blood film are required. The user must be familiar with
the appearance of normal histograms to make a useful assessment.
Red Blood Cells
The sizes of the peaks vary depending on the frequency and size of each cell
type. Therefore, it is possible to observe microcytic (small red cells) and
macrocytic (large red cells) red blood cell populations from the size and
position of the peaks.
White Blood Cells
Nucleated RBC’s are represented in the histograms as lymphocytes; therefore,
if the lymphocyte peak is abnormally high it would be advantageous to consult
a blood film. Although unpredictable in leukaemic samples, the appearance of
the histogram can be a useful tool to aid the diagnosis of leukaemia.
Depending on the condition, some cells may form large peaks in either the
lymphocyte or granulocyte area, or form into one large peak which can span all
3 differential areas. Note that cell lineage cannot be determined by the
appearance of the histogram. 
Platelet histograms can be used to determine the volume distribution of platelet populations. Thrombocytopenia is caused by either the failure of production or by increased consumption. Platelet distribution width (PDW) is increased in the latter group producing large platelets which are depicted on the right side of the histogram. Platelet histograms are also useful to assess if a thrombocytopenia is genuine or due to a sample quality problem such as aggregates. If platelets are aggregated an atypical picture is seen with uneven distribution.
