The 7 diff hematology analyzer has become a core component of modern diagnostics in both human and veterinary medicine, because it delivers an extended white blood cell differential, morphology-aware reporting and multi-parameter interpretation in a single automated run. By combining AI-based Complete Blood Morphology (CBM) with maintenance-free consumables, these analyzers support lab-grade decision making in hospitals, primary care mini-labs and companion-animal clinics.

Technical definition of a 7 diff hematology analyzer

A 7 diff hematology analyzer provides at least a seven-part white blood cell differential and can identify immature and abnormal cell populations such as NST (immature neutrophils), NSG (nuclear-shifted granulocytes), NSH (hypersegmented neutrophils) and reticulocytes (RET). Beyond the WBC split, contemporary 7-diff systems report extended parameters including NLR, PLR, platelet activation indices and reticulocyte metrics that refine interpretation of infection, inflammation, bone marrow function and anemia.

Ozelle’s AI-powered platforms implement 7-diff analysis using CBM technology, combining high-resolution optical imaging with deep neural networks trained on tens of millions of blood cell images, so that each CBC is accompanied by morphology-aware, interpretation-ready information rather than simple counts.

Human 7-diff analyzers: EHBT-75 and EHBT-50

EHBT-75: professional 7-diff auto hematology analyzer

EHBT-75 is Ozelle’s professional 7-diff auto hematology analyzer for human diagnostics, designed to deliver deep hematology and morphology for hospital laboratories and advanced diagnostic centers. It couples high-resolution imaging, liquid-based staining and AI-driven recognition to generate CBC + 7-diff + morphology-rich reports from a small blood sample.

• Analysis principle: AI-powered CBM for CBC, photoelectric colorimetry for HGB, with 7-diff WBC differential.
• المعلمات: Approximately 37 hematology parameters, covering WBC subsets (NEU, LYM, MON, EOS, BAS), immature and abnormal neutrophil markers (NST, NSG, NSH), atypical lymphocytes (ALY), RBC indices, RET, and platelet indices such as PAg, NLR and PLR.
• Abnormal cell detection: Automated detection of NST, NSG, NSH, ALY, PAg and RET to support recognition of severe infections, megaloblastic anemia, myelodysplastic syndromes and bone marrow stress states.
• Consumables and maintenance: Single-use test cartridges stored at room temperature, dry-test design without internal fluidics, maintenance-free operation.
• Automation and connectivity: Fully automatic sample pre-processing and reporting; LIS/HIS connectivity through USB, Ethernet, Wi-Fi and Bluetooth.

These capabilities allow EHBT-75 to function as an intelligent blood diagnostics engine rather than a conventional counter, particularly in settings where morphology and extended indices influence therapy decisions.

EHBT-50 Mini Lab: 7-diff hematology integrated with immunoassay and biochemistry

EHBT-50 extends 7-diff hematology into a multi-functional mini-lab platform for decentralized human diagnostics. It combines 7-diff CBC, biochemistry and immunoassay in a single analyzer with AI + CBM as the hematology core.

• 7-diff WBC differential with NST, NSG, NSH and ALY markers.
• RBC indices and reticulocyte counts, enabling evaluation of anemia and marrow response.
• Platelet indices such as MPV, PDW, PCT, PAg, PLR and NLR to assess thrombocyte function and systemic inflammation.

On top of this, the same cartridge can incorporate markers such as CRP/hs-CRP, NT-proBNP, troponin, SAA and basic liver/kidney chemistry, turning the device into an AI-enabled point-of-care mini lab for clinics and small hospitals. For decentralized settings, this allows 7-diff-level hematology to be combined with key cardiometabolic and inflammatory markers without separate instruments.

Human clinical application scenarios

Hospital and reference laboratories

• Advanced infection work-up: Quantifying NST, NSG and NSH alongside NLR and PLR to characterise bacterial sepsis, severe inflammation and mixed infection patterns.
• Hematologic disease assessment: Detecting abnormal granulocyte morphology, hypersegmented neutrophils and atypical lymphocytes to support investigation of megaloblastic anemia, myelodysplastic syndromes and leukemias.
• Therapy monitoring: Tracking reticulocyte counts and extended platelet indices to evaluate marrow recovery and treatment response.

AI-assisted morphology allows laboratories to standardise interpretations that were previously heavily dependent on individual microscopists, while still enabling manual review when required.

Decentralized primary and secondary care

EHBT-50 Mini Lab enables 7-diff-level CBC in decentralized environments such as community hospitals, private diagnostic centers and advanced primary care clinics.

• Point-of-care triage: Combining 7-diff CBC with CRP/SAA and basic chemistry in one run to stratify patients with suspected infection, acute coronary syndromes or decompensated chronic disease.
• Integrated chronic disease follow-up: Using extended hematology and inflammatory ratios to complement HbA1c, renal function and lipid profiles in follow-up pathways.
• Standardised interpretation support: Leveraging AI-generated comments and morphology flags to provide consistent decision support to non-specialist clinicians while preserving clinician oversight.

Veterinary 7-diff analyzers: EHVT-50 and EHVT-75

EHVT-50: 7-diff veterinary mini lab for small-animal practice

EHVT-50 is a veterinary multi-functional analyzer that integrates 7-diff CBM hematology, immunoassays, urine sediment analysis and fecal microscopy in a single platform designed for companion-animal practice. It is engineered to shorten the diagnostic window in dogs and cats while maintaining lab-grade analytical performance.

• 7-diff CBC with approximately 38-42 parameters for canine and feline patients, including neutrophil maturation markers (NST, NSG, NSH), atypical lymphocytes and reticulocytes (RET).
• AI-powered cell morphology: CBM technology with AI image recognition provides microscope-level classification and attaches real cell images to each report for pathologist-level review when necessary.
• Species-specific ranges: Reference intervals and algorithms tuned for dogs and cats, with planned extension to additional species.

EHVT-50 extends the same imaging and AI infrastructure to urine analysis, fecal analysis and veterinary immunoassays for inflammation, pancreatitis, thyroid, cardiac and infectious disease evaluation.

EHVT-75: compact 7-diff veterinary CBC platform

EHVT-75 provides a more compact veterinary CBC platform built on the same AI + CBM framework, combining 7-diff hematology with urine and feces analysis in a compact footprint for practices where space is limited. It identifies abnormal blood cells such as RET, SPH, ETG, APLT and P-LCC, with visual evidence to support morphological evaluation.

Both EHVT-50 and EHVT-75 rely on AI-assisted reporting via Ozelle’s veterinary diagnostic ecosystem, enabling structured veterinary reports and optional AI-assisted diagnostic consultation for small-animal medicine.

Veterinary clinical application scenarios

General small-animal clinics

In everyday small-animal practice, a veterinary 7 diff hematology analyzer allows clinicians to perform comprehensive first-line diagnostics on site.

• Dogs and cats presenting with fever, lethargy, weight loss, chronic diarrhea or suspected systemic disease.
• Pre-operative screening for elective surgery, where CBC + 7-diff, basic biochemistry and inflammatory markers help evaluate surgical risk.
• Monitoring of chronic conditions such as immune-mediated disease, renal insufficiency or endocrine disorders that require periodic hematology and multi-parameter follow-up.

By integrating 7-diff CBC with urine and feces analysis, EHVT-50 enables a single analyzer to cover most routine internal medicine pathways in companion-animal practice.

Emergency veterinary clinics and mobile services

Emergency veterinary facilities and mobile services face unique constraints: limited time, limited staff and a need for rapid, actionable results. EHVT-50 is explicitly described as a veterinary CBC machine engineered for emergency clinics, providing 7-diff hematology with 42 parameters and integrated urine, feces and immunoassay testing.

• Rapid differentiation between inflammatory, infectious and hemorrhagic processes using CBC, reticulocyte counts, CRP/SAA and organ-specific markers.
• Earlier stabilisation decisions in cases such as sepsis, acute abdomen, pancreatitis and severe anemia.
• Reduced reliance on external laboratories during critical windows, while maintaining image-level evidence that can be shared with referral hospitals or specialists.
