What Is a Hematology Analyzer?
A Hematology Analyzer is a sophisticated laboratory instrument used to automatically count and identify blood cells. It is one of the most essential devices in every clinical laboratory, as the Complete Blood Count (CBC) is the most frequently ordered test by physicians in daily clinical practice.
Before the advent of Hematology Analyzers, blood cell counting was performed manually using a hemocytometer under a microscope — a time-consuming process prone to human error. Today, with modern technology, a complete blood count can be completed in minutes with far greater accuracy.
Parameters Measured in a Complete Blood Count
Modern Hematology Analyzers like the BM-H3900S can measure up to 21 blood parameters simultaneously, providing a comprehensive picture of the patient's health status:
| Parameter | Full Name | Clinical Function |
|---|---|---|
| WBC | White Blood Cell Count | Detects infections, leukemia, and immune disorders |
| RBC | Red Blood Cell Count | Detects anemia and polycythemia |
| HGB | Hemoglobin | Measures oxygen-carrying capacity of blood |
| HCT | Hematocrit | Percentage of red blood cell volume to total blood |
| MCV | Mean Corpuscular Volume | Average red blood cell size (anemia classification) |
| MCH | Mean Corpuscular Hemoglobin | Average hemoglobin per red blood cell |
| MCHC | Mean Corpuscular Hb Concentration | Hemoglobin concentration in red blood cells |
| PLT | Platelet Count | Blood clotting evaluation and bleeding risk |
| RDW | Red Cell Distribution Width | Red blood cell size variation |
| MPV | Mean Platelet Volume | Average platelet size |
White Blood Cell Differentiation (3-Part Diff)
The BM-H3900S can differentiate white blood cells into 3 main populations:
- Lymphocytes — Plays a role in adaptive immunity (viral infections, autoimmune diseases)
- Granulocytes (Neutrophils) — Primary defense against bacterial infections
- Monocytes (Mid-cells) — Involved in phagocytosis and innate immunity
BM-H3900S Hematology Analyzer Advantages
Specifications & Advantages:

- Low reagent consumption — Saves laboratory operational costs
- Auto-sampling — Reduces direct contact with blood samples
- Quality Control — Integrated QC system to ensure result accuracy
- Data storage — Can store thousands of test results
- LIS connectivity — Can connect to Laboratory Information Systems
Required Supporting Reagents
To operate the Hematology Analyzer optimally, the following supporting reagents are needed:
- BM Diluent — Dilution reagent to dilute blood samples before analysis
- BM Lyse — Reagent to dissolve red blood cells, detecting total WBC and hemoglobin levels
- BM Cleanser — Cleaning reagent to flush fluid pathways and maintain instrument performance
When Is a Complete Blood Count Needed?
- Routine medical check-ups — As an annual health screening
- Symptom evaluation — Chronic fatigue, prolonged fever, abnormal bleeding, unexplained bruising
- Treatment monitoring — Chemotherapy, anticoagulant therapy, medications affecting bone marrow
- Pre-surgery — Mandatory screening before surgical procedures
- Disease diagnosis — Anemia, infection, leukemia, thrombocytopenia, and other hematological disorders
