A hematology analyzer lets you quickly examine blood cells using advanced technology.
This device automates the process, so you do not need to count cells by hand.
You benefit from more accurate results because the machine uses digital tools that reduce human error.
Automated systems create consistent blood films and use artificial intelligence to classify cells.
This means you can trust the results to help diagnose health conditions faster and more reliably.
Hematology analyzers automate blood-cell counting, providing fast, accurate results that help diagnose health conditions quickly.
Proper sample handling is crucial to maintain blood-cell quality and ensure reliable test outcomes.
Two main technologies—impedance-based counting and light-scatter—work together to identify and count different blood cells precisely.
Advanced analyzers use artificial intelligence to improve accuracy, reduce errors, and support detailed blood analysis.
Using hematology analyzers boosts lab efficiency, saves time, and improves patient care by delivering reliable and detailed blood-test results.
When you use a hematology analyzer, you start with careful sample preparation.
This step helps you get accurate results and keeps the blood cells in good condition.
| Step | Best Practice |
|---|---|
| Collection | Use EDTA tube to prevent clotting. |
| Needle size | Choose appropriate gauge to avoid cell damage. |
| Mixing | Gently invert tube; do not shake. |
| Smear | Prepare from fresh blood immediately. |
| Storage | Refrigerate whole blood (do not freeze); keep smears at room temperature. |
| Anticoagulant | Avoid heparin (causes clumping). |
| QC | Watch for shrinkage, clumping, or other artifacts. |
> Tip: Modern analyzers use barcode scanning and automated pipetting to reduce contamination and clerical errors.
| Element | Description |
|---|---|
| Principle | Wallace Coulter, 1953. |
| Setup | Two electrodes separated by a small aperture in conductive solution. |
| Detection | Cell passage changes electrical resistance → voltage pulse. |
| Pulse size | Proportional to cell volume. |
| Speed | Counts thousands of cells in < 1 min. |
Excellent for RBC, WBC, PLT counts.
Limitation: Size only; limited WBC subtyping.
Laser light hits each cell.
Forward scatter → cell size.
Side scatter → internal complexity/granularity.
Fluorescence (with dyes) → DNA/RNA content.
Enables 5-part WBC differential and detection of immature/abnormal cells.
> Note: Combining both methods yields fast, reliable, and detailed results superior to manual counts.
After counting, built-in software processes the raw data:
Generates histograms & scattergrams.
Reports CBC (WBC, RBC, Hb, PLT, indices).
Provides 5-part differential (Neut, Lymph, Mono, Eo, Baso).
Flags abnormal results & suggests repeat if necessary.
Stores > 100,000 patient files (expandable via USB).
AI Enhancements
Convolutional neural networks for cell imaging.
Support-vector machines / Random forests for classification & risk prediction.
Automated cleaning & rinsing → minimizes carry-over.
Closed-tube sampling → operator safety.
Micro-volume capability → ideal for pediatrics.
Platelet-clump de-aggregation & multi-fold detection → accurate low-platelet counts.
> Tip: Automation ensures reproducible results even with difficult samples.
Optical, impedance, digital imaging.
Flow cytometry + VCS (Volume, Conductivity, Scatter).
Deep-learning models (YOLO) for rapid cell recognition.
AI boosts precision and flags morphologic anomalies.
