A hema analyzer — short for hematology analyzer — is a medical device used to automatically count, classify, and analyze blood cells from a patient sample. These instruments are central to diagnosing a wide range of conditions, from anemia and infections to clotting disorders and hematological cancers. With the rise of artificial intelligence (AI) and imaging technology, today’s hema analyzers deliver unprecedented precision at the point of care.
What Does a Hema Analyzer Measure?
A hema analyzer performs a Полный подсчет крови (CBC), one of the most commonly ordered tests in clinical medicine. It examines the three major cell types in blood: white blood cells (WBC), red blood cells (RBC), and platelets (PLT), along with dozens of derived parameters.
Modern 7-part differential hema analyzers go significantly further. The Ozelle EHBT-50, for instance, measures 37 параметров in a single run — including advanced markers such as Neutrophilic Stab Granulocytes (NST), Neutrophilic Segmented Granulocytes (NSG), Neutrophilic Hypersegmented Granulocytes (NSH), Reticulocytes (RET), Platelet Aggregates (PAg), and Atypical Lymphocytes (ALY) — all of which carry vital diagnostic significance.

How Does a Hema Analyzer Work?
Traditional hematology analyzers relied on two main methods: the impedance method (measuring voltage pulses as cells pass through an aperture) and flow cytometry (using laser light to detect fluorescence and scatter from stained cells). These methods, developed in the 1950s and 1970s respectively, laid the groundwork for modern blood analysis.
Today’s most advanced hema analyzers use AI-powered cell morphology (CBM) technology. Rather than counting cells by electrical signals alone, these systems capture high-resolution microscopic images of every cell and use deep learning algorithms to classify them visually — essentially replicating what a trained laboratory pathologist would do under a microscope, but far faster and with greater consistency.
Ozelle’s breakthrough CBM (Complete Blood Morphology) platform combines three components:
- Expert Brain — A deep-learning AI model trained on over 40 million real blood cell samples, recognized at the 2022 World Artificial Intelligence Conference (WAIC)
- Precision Eyes — SwissOptic custom lenses with 4-megapixel resolution at 50 frames per second
- Technician Hands — A fully automated mechanical arm with 1 μm repeatability positioning accuracy
Types of Hema Analyzers
Not all hema analyzers are the same. They vary in the number of cell types they can differentiate (the “differential”), their throughput, and additional multi-functional capabilities.

The Rise of All-in-One Multi-Functional Hema Analyzers
A major trend in modern diagnostics is the consolidation of testing into a single device. Traditionally, a clinic would need separate analyzers for blood counts, immunoassays, and biochemistry panels — each requiring dedicated reagents, space, and trained operators.
The Ozelle EHBT-50 Minilab, for example, integrates hematology, immunofluorescence assay (FIA), dry chemistry biochemistry, urine analysis, and fecal analysis into one compact device (400 × 350 × 450 mm, 15 kg). Clinicians can run combined panels such as CBC + CRP/SAA for infection typing, CBC + TSH/FT3/FT4 for thyroid screening, CBC + HbA1c/GLU for diabetes management, or CBC + NT-proBNP for heart failure assessment — all from a single 30 µL capillary blood sample taken from a fingertip.
Immunoassay & Biochemistry Panels Available on the EHBT-50
| Clinical Need | Test Panel |
|---|---|
| Infection Severity | CBC + CRP, SAA, PCT, IL-6 |
| Диабет | CBC + HbA1c, Glucose, TG, TC |
| Thyroid Function | CBC + TSH, FT3, FT4, T3, T4 |
| Cardiac Markers | CBC + cTnI, NT-proBNP, CK-MB, Myo |
| Kidney Function | CBC + mALB, NGAL, β2-MG, UA, Cr, BUN |
| Метаболизм костной ткани | CBC + 25-OH Vitamin D |
| Early Pregnancy | CBC + β-HCG, Progesterone |

Where Are Hema Analyzers Used?
The applications of hema analyzers are extremely broad. Thanks to compact designs and automation, they are no longer confined to hospital central labs:
- Hospital laboratories — High-throughput routine CBC testing
- General practitioner and private clinics — Point-of-care testing during consultations
- Pharmacies — In countries such as Brazil, Italy, France, USA, and Australia, pharmacies are permitted to offer medical testing
- Emergency departments and ambulances — Rapid triage decisions
- Mobile health units — Remote and underserved community diagnostics
- Veterinary clinics — Dedicated analyzers (e.g., Ozelle EHVT-50) for canine and feline blood analysis
Understanding Advanced Differential Parameters
One of the most clinically valuable features of 7-diff hema analyzers is the ability to detect immature and abnormal white blood cell subtypes that a standard 5-diff analyzer would miss:
- NST (Neutrophilic Stab Granulocyte): Includes band neutrophils and earlier precursors. Elevated NST signals a “left shift” — indicating bone marrow stress, commonly in bacterial infection or sepsis.
- NSG (Neutrophilic Segmented Granulocyte): Mature neutrophils, the body’s primary defense against bacterial infection.
- NSH (Neutrophilic Hypersegmented Granulocyte): Neutrophils with more than 5 nuclear lobes, indicating abnormal or dysregulated cell maturation, often seen in B12/folate deficiency.
- RET (Reticulocyte): Immature red blood cells still containing residual RNA; the reticulocyte count is essential for evaluating bone marrow response to anemia.
- PAg (Platelet Aggregate): Clumped platelets that may indicate pseudothrombocytopenia or activation states.

Часто задаваемые вопросы (FAQ)
Q1: What is the difference between a 3-diff and a 7-diff hema analyzer?
A 3-diff (3-part differential) analyzer separates white blood cells into three groups: granulocytes, lymphocytes, and mid-cells. A 7-diff analyzer (like the Ozelle EHBT-50 and EHBT-75) identifies up to seven distinct WBC subpopulations — including NST, NSG, NSH, EOS, BAS, LYM, and MON — providing far deeper clinical insight into immune status, infection type, and bone marrow activity.
Q2: How much blood is needed for a hema analyzer test?
Advanced AI-based hema analyzers require very small sample volumes. The Ozelle EHBT-50 uses only 30 µL for testing (60 µL for loading) from a fingertip capillary sample, making it particularly suitable for infants, children, and elderly patients.
Q3: How long does it take to get results from a hema analyzer?
Modern AI hema analyzers deliver a complete CBC morphology report in approximately 6 минут на образец. Throughput is typically 10 samples per hour for most point-of-care models.
Q4: Can a hema analyzer detect abnormal cells?
Yes. AI-powered hema analyzers can identify morphologically abnormal cells such as schistocytes (fragmented RBCs), echinocytes (spiky RBCs), teardrop cells, hypersegmented neutrophils, and atypical lymphocytes — findings that are clinically significant for conditions like hemolytic anemia, liver disease, vitamin deficiencies, and hematological malignancies.
Q5: Do modern hema analyzers require a lot of maintenance?
No. Devices like the Ozelle EHBT-50 use a maintenance-free single-use cartridge design — there are no fluid pipelines to clean, no reagent containers to top up, and no risk of cross-contamination between samples. Test kits can be stored at room temperature for up to 2 years.
Q6: What is CBM (Complete Blood Morphology) technology?
CBM is an AI-driven advancement over traditional CBC counting. Instead of only counting cells by electrical signals, CBM captures high-resolution microscopic images of every cell and uses convolutional neural networks (CNN) trained on tens of millions of real samples to classify them — producing results that approach the accuracy of expert pathologists.
Q7: Can a hema analyzer be used in a veterinary clinic?
Yes. Dedicated veterinary hema analyzers exist for this purpose. The Ozelle EHVT-50 supports 7-diff CBC, urine analysis, fecal analysis, and immunoassays specifically for canine and feline species, with additional species available by customization.
Q8: Is AI-based hema analysis as accurate as manual microscopy by a trained technician?
AI hema analyzers have demonstrated correlation coefficients (R²) of 0.97–0.999 when compared against gold-standard systems like Sysmex NX and Beckman Coulter DxH, and have been validated against manual review across 125+ clinical samples. The algorithms are continuously improved through large-model training on real-world clinical data.
Hema analyzers have evolved from simple cell counters into sophisticated AI-powered diagnostic platforms capable of delivering lab-grade insights from a single drop of blood. Whether in a major hospital, a rural clinic, or a pharmacy, the latest generation of analyzers — like those developed by Озель — is making comprehensive blood diagnostics faster, more affordable, and more accessible than ever before.
