Tertiary hospital hematology departments evaluating POCT for outpatient and day ward units need to balance the apparent cost of single-use, all-in-one reagent cartridges against the hidden costs of central lab workflows and delayed results.

The challenge of POCT in tertiary hematology

In many tertiary hospitals, hematology specialists face a familiar dilemma: outpatients and day ward patients often require repeated complete blood counts, inflammation markers, and basic biochemistry before treatment decisions can be made, yet most of these tests are performed in a central laboratory. This model leads to longer turnaround times, repeated patient visits, and significant pressure on both phlebotomy and laboratory staff.

When considering a POCT hematology solution, decision-makers must therefore look beyond the price of consumables and ask how a system affects the entire clinical and operational pathway. EHBT-50 Mini Lab – a 7-diff multi-functional analyzer from Ozelle – is specifically designed to address these end-to-end pain points rather than just replace a single instrument.

What makes EHBT-50 different?

EHBT-50 combines CBC with blood cell morphology, immunoassay, and dry chemistry within one compact analyzer using an AI-driven, image-based CBM (Complete Blood Morphology) engine. It integrates CBC and PBS capabilities by capturing high-resolution images of blood cells and applying deep learning models trained on more than 40 million samples to classify cell types and abnormalities.

Technically, the analyzer functions as a digital microscope, hemocytometer, and spectrophotometer in one, delivering a “gold standard” panel of 42 parameters across RBC, PLT, WBC, immunoassay, and basic chemistry in a single run. For outpatient and day ward POCT, this means clinicians can obtain hematology, inflammatory markers, and basic biochemical indicators from a single test without sending multiple tubes to different analyzers.

All-in-one cartridge design and what it means for cost

The core consumable of EHBT-50 is a single-use, all-in-one reagent card that integrates the reagents and reaction chambers needed for CBC, immunoassay, and dry chemistry testing. Each card is designed for one patient sample, with a shelf life of up to two years for hematology components and 18 months for immunoassay and biochemistry at room temperature, minimizing cold-chain and storage constraints.

From a procurement perspective, this cartridge consolidates what would otherwise be multiple reagent systems – hematology reagents, stains, immunoassay strips, and dry chemistry slides – along with waste management. All waste liquid is stored inside the cartridge, reducing infrastructure costs related to drainage, decontamination, and maintenance of plumbing and waste containers.

Although the unit price of a single all-in-one cartridge may initially seem higher than traditional hematology reagents, it effectively replaces several categories of consumables and reduces the need for additional disposables such as separate fluorescence cards, chemistry slides, and associated plasticware.

Time is money: six-minute multi-panel testing

EHBT-50 performs fully automated sample preparation, staining, scanning, and analysis in approximately six minutes per sample. It accepts both capillary blood (approximately 30 microliters) and venous EDTA samples (around 10000, allowing flexible sampling strategies in outpatient and day ward settings.

In a conventional workflow, CBC, CRP/PCT, and basic biochemistry are often routed to separate instruments in the central lab, with batching and transportation adding delays. With EHBT-50 located in the clinic or day ward, clinicians can obtain a combined report – including CBC, 7-diff, reticulocytes, platelet morphology, CRP/CRP-SAA, IL-6, PCT, HbA1c, cardiac markers (such as cTnI and CK-MB), and key chemistry parameters (such as ALT/AST, glucose, UACR, and UREA) – before the patient leaves the department.

For hematology specialists, this fast, multi-panel output has two economic implications: it shortens the pathway from sampling to treatment decision and reduces repeat visits or admissions caused by incomplete or delayed test results. When evaluating cartridge cost, these time savings and reduced patient movements should be included as part of the overall return on investment.

Comprehensive parameter coverage for hematology decision-making

EHBT-50’s parameter set is designed for deeper hematology insight than a simple 3-diff analyzer. On the hematology side, it measures RBC indices (including RBC, HGB, HCT, MCV, MCH, MCHC, RDW-CV, RDW-SD, and RET), platelet parameters (PLT, MPV, PDW, PCT, PAg, PLCC, PLCR), and a detailed WBC differential.

The WBC panel includes NST (neutrophilic stab granulocytes), NSG (mature neutrophils), NSH (hypersegmented neutrophils), lymphocytes, monocytes, eosinophils, basophils, and composite ratios such as NLR. The presence of NST and NSH supports identification of left shifts and abnormal maturation, which are important for early detection of infections, bone marrow stress, and hematologic malignancies.

Immunoassay parameters include CRP, CRP-SAA, T3, T4, TSH, HbA1c, NT-proBNP, D-Dimer, PCT, IL-6, vitamin D, cTnI, and CK-MB, while dry chemistry covers panels such as ALT/AST/UACR, glucose/UAT/CTG, and ALT/AST/ALB/TB, as well as UACR/UREA. This combinations allows outpatient hematology clinics to monitor anemia, infection, inflammation, cardiac stress, diabetes control, and organ function in one sitting, using a single device and cartridge.

The breadth of parameters is crucial in evaluating cartridge cost: one cartridge does not just pay for a CBC but for a comprehensive diagnostic profile that often replaces multiple separate tests and lab workflows.

AI-driven morphology: value beyond numeric results

A key differentiator of EHBT-50 is its AI-based image analysis, which delivers digital microscopy-level morphology. The CBM engine uses high-resolution imaging, Z-stack technology, and convolutional neural networks to identify RBC abnormalities such as schistocytes, echinocytes, teardrop cells, and reticulocytes, as well as platelet aggregation and other morphological clues.

The system produces visual images of WBC, RBC, and PLT, along with histograms, and can flag potential pathological and morphological abnormalities to support clinical inference. For hematology specialists, this bridges the gap between automated counting and manual microscopy, providing a richer dataset from a single POCT run.

When assessing cost-effectiveness, this visual evidence adds value in several ways: it reduces the need for additional smear review in some cases, supports early suspicion of hematologic disease, and enriches follow-up monitoring in chronic hematology patients without requiring full manual microscopy in every visit.

Operational savings: maintenance-free, standardized workflows

EHBT-50 is designed to be maintenance-free, with no need for complex calibration routines, daily reagent priming, or external waste management infrastructure. The device automates sample pretreatment and analysis with a “one key test” approach, simplifying operation for nursing staff and junior technicians in outpatient or day ward settings.

The standardized, sealed cartridge and automated mechanical arm minimize operator-dependent variability and bio-safety risks. Because reagents are pre-packaged and waste is contained, installation in non-laboratory environments becomes easier and safer, with lower demands on ventilation, drainage, and specialized cleaning procedures.

These operational features translate into savings on training, downtime, and technical service. The removal of many hidden costs – such as frequent maintenance, unexpected instrument failures due to liquid systems, and staff time spent managing reagents – is an important factor when comparing the cost per test of single-use cartridges versus traditional lab reagents.

Economic perspective: from per-test cost to total value

To fairly evaluate EHBT-50 in outpatient and day ward POCT, tertiary hematology departments should move from a narrow per-test reagent cost comparison to a total value framework. This includes several dimensions:

• Direct consumables: One all-in-one cartridge replacing multiple reagents (hematology, immunoassay, chemistry) and disposables.
• Equipment and infrastructure: A single compact device instead of several analyzers, no additional plumbing or waste lines, and minimal environmental requirements.
• Workflow and labor: Reduced sample transport, fewer manual steps, and minimized manual microscopy in routine follow-up cases.
• Patient pathway: Fewer repeat visits, quicker treatment decisions, and improved patient satisfaction due to same-visit results.
• Clinical quality: Enhanced morphological insight, infection and inflammation profiling, and integration of cardiac and metabolic markers in one test, supporting more accurate and timely decisions.

When all these elements are considered, the “cost” of an EHBT-50 cartridge essentially buys a mini-laboratory session at the point of care, rather than a single CBC. For tertiary hematology departments dealing with complex patients and high volumes, this can significantly rebalance the economics in favor of POCT.

Strategic deployment: outpatient and day ward use cases

In outpatient hematology clinics, EHBT-50 can be used for pre-consultation screening, on-visit monitoring of chemotherapy or immunosuppressive therapy, and quick evaluation of suspected infection or flare. By the time the patient meets the hematologist, CBC, differential, inflammatory markers, and basic biochemical indicators are already available, allowing a single, integrated consultation.

Day ward units managing infusions or short-stay therapies can use EHBT-50 to check baseline status before procedures, assess immediate post-treatment changes, and monitor for early signs of complications such as infection, liver injury, or myocardial stress. Because each test is run on a single cartridge with minimal hands-on time, nurses can operate the system as part of routine workflow without waiting for central lab returns.

In both scenarios, the reduced need to send samples to the central lab and the ability to make same-visit decisions directly translate into operational savings and improved patient throughput, which offset the apparent higher unit cost of cartridges.

Digital ecosystem and long-term value

Beyond the device itself, Ozelle provides a smart IoT platform that connects EHBT-50 units to centralized systems for sample analysis management, equipment and consumables tracking, and operations management. This includes features such as order management, test tracking, mobile and web access, and AI-powered diagnostic reports with clinical interpretation suggestions.

For tertiary hospitals operating multiple sites or medical alliances, this connectivity helps standardize POCT practice, monitor device performance, and integrate POCT data into broader diagnostic and treatment workflows. Over time, these digital tools enhance the value of each cartridge by turning test results into actionable, trackable data within a larger care network.
