Calibration of hematology analyzers is necessary to ensure accurate and consistent test results. The document discusses the definition of calibration, why it is needed, recommended calibration frequency according to the manufacturer, and documentation requirements. Quality control is important for monitoring the analyzer's performance but does not replace the need for periodic calibration adjustments. Common quality control methods involve rules and Levey-Jennings charts to detect errors and ensure the analyzer remains in control.
Preanalytical quality control practices in clinical laboratoryDr. Rajesh Bendre
Preanalytical variables contribute maximally to lab errors. However, these variables are most difficult to control as they include human dependency for phlebotomy skills & pretest patient conditioning. Quantifying & monitoring these variables is also more challenging. Use of checklists, continuous training, competency assessments, internal audits & clinician education for appropriate test utilization form some of the tools for improving the preanalytical processes.

In the haematology laboratory it is essential to ensure that the right test is carried out on the right specimen and that the correct results are delivered to the appropriate recipient without delay.
Quality control (QC) is defined as measures that must be included during each assay run to verify that the test is working properly.
Internal quality control (IQC) is monitoring the haematology test procedures to ensure continual evaluation of the reliability of the daily work of the laboratory with validation of tests before reports are released

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

3. IS THERE A NEED TO CALIBRATE SYSMEX HEMATOLOGY
ANALYZER ?
YES
4. Definition
Calibration involves any adjustments made
to an instrument to correct the results
recovered so that they match “truth”, which
is defined by standards or reference
procedures.
🠜This procedure ensures that results for blood
specimens analysed on all instruments of a
given model will show worldwide homology.
Why Calibration Necessary?
5. Calibrator
WBC/RBC count calibration ICSH reference method for enumeration of erythrocytes and leucocytes
Platelet count calibration ICSH refernece method for platelet method
HGB calibration ICSH reference method on hemoglobinometry
HCT calibration ICSH reference method for the packed cell method
1. A Reference material whose value is used for the independent variable in a
calibration function.
2. SCS-1000 hematology calibrator is used for WBC, RBC, PLT, HGB and HCT
calibration.
3. The calibration value assignment of the SCS-1000 is traceable to International
conventional reference measurement procedures.

6. QC vs Calibration
QC is Not Calibration!
• QC is checking to see if the analyzer is producing
correct results
– checking the instrument’s calibration and other analytical
processes
• Calibration is “setting” the analyzer to give correct
results
– Use calibration material/calibrator, not QC material
7. What is Frequency of Calibration?
Comply with
1. Manufacturer’s recommendations
2. Laboratory quality policy
3. Regulatory body regulations
4. Accreditation bodies requirements.
8. Calibration Requirement Recommended by Sysmex
The manufacturer recommendations (in the operator manual)
are as following :
1. During installation of analyzer at customer site.
2. After a major Preventive maintenance or change of major components
3. When QC data begin to reflect an unusual trend or are outside of the
acceptable limits and cannot be corrected by maintenance troubleshooting the
instrument
4. The laboratory's established schedule requires more frequent calibration or
calibration verification
5. The Sysmex service representative advised to do so
6. Regulatory standards require periodic calibration verification.
9. Record of Calibration
Calibration must be documented and the
following record must be maintained:
1. Calibration Report with calibrator data
and QC data and printouts
2. Certificate of calibration (optional)
• Remarks:
1. QC must be performed after calibration to verify that the calibration is
successful
2. Calibration report and certificate of calibration (optional) must be issued
by service organisation.
3. Standard template for commissioning report (include calibration) and
calibration report can be download from NPP.
12. Spot the Difference
Low accuracy and low precision (poor repeatability)
Stone age man missed the bull's-eye and the 3 attempts were
not near each other.
Low accuracy but high precision
Robin Hood's Merry Man missed the bull's-eye but the 3
attempts were near each other.
Higher accuracy but low precision
Native American's 3 attempts were near the bull's-eye, but
were not near each other.
High accuracy and high precision
Olympic archer hit the bull's-eye 3 times!
13. • Definition
A system of maintaining standards in
manufactured products by testing a sample of the
output against the specification
• Purpose
Ensure that reported results are accountable
Quality Control
14. • A quality control should be performed:
– Before any start of operation
– At least every 8 hours during operation
– After replenishment of components
– After maintenance
– If there is any doubt about the accuracy of the
analysis value
Quality Control
16. XN CHECK Level 1:
• New platelet componet can be stained
by PLT-F stain.
*Required for monitoring PLT-F
XN CHECK L2 and L3:
• do not include stainable thrombocyte
components, the cell concentration does
not allow that (technical limitation)
Expected PLT (103/µl) Concentrations
• Low (L1)
• Normal (L2)
• High (L3)

22. What do you do when your QC run is out?
• First do not release any results
• Do NOT automatically repeat the control!
• Investigate and determine the type of error (random
or systematic)
• Look at your QC/QA Records
– Instrument function and condition
• Any sign of instrument deterioration (frequency and length of
downtime & why, unscheduled PM), temperature checks
– Calibration and Calibration verification
• Lot #, expiry date, date (& why) of calibration
– Previous control runs (any bias observed)
• Lot#, expiry date of current run
– Reagent Storage, Reconstitution and Handling
