Automated Hematology Analyzer with Integrated Body Fluid Module

What is the Automated Hematology Analyzer with Integrated Body Fluid Module?

This analyzer adds a body fluid mode that counts cells in cerebrospinal, pleural, peritoneal and synovial fluid using the same flow cytometry channel as the blood count. It suits hospital laboratories that currently perform body fluid counts manually in a chamber.

Overview

Body fluid analysis uses the flow cytometry channel with dedicated reagents and software rules. The instrument reports total nucleated cells, red cells and white cells, and in many models distinguishes mononuclear from polymorphonuclear cells, which is important for differentiating infectious from non-infectious effusions. Some platforms also provide a count for synovial fluid crystals only as a screen, and depend on microscopy for identification. Sample volume requirements are low, often 100 to 200 microliters, which matters for cerebrospinal fluid from infants. Because body fluid cells differ in size and fragility from blood cells, the mode must be validated locally against manual chamber counts, including samples with low counts and with degenerated cells.

How does it work?

An automated hematology system is an assembly of modules rather than a single instrument. The analytical module performs impedance counting and laser flow cytometry to produce the complete blood count and five-part differential. Pre-analytical elements include a bulk loader, a centrifuge or mixing station, and a barcode-driven sorter that directs tubes according to their test orders. Post-analytical elements include a slide maker and stainer that prepares films for samples meeting defined review criteria, a digital morphology scanner that takes images of the films, and middleware that applies review rules, routes work between instruments and manages quality control across the system. Communication uses barcode identification and HL7 or ASTM interfaces to the laboratory information system, so that a tube is measured, reviewed and reported with minimal manual handling, while the middleware records which rules were applied to each result.

What are the key features?

• Body fluid channel with dedicated reagent and software rules
• Mononuclear and polymorphonuclear cell differentiation
• Low sample volume mode from 100 microliters
• Automatic flagging when results need microscopic confirmation
• Same analyzer for complete blood count and body fluid testing
• Body fluid quality control material support

What are the technical specifications?

A typical automated hematology analyzer with integrated body fluid module configuration offers body fluid sample volume of 100–200 µL, reportable fluid parameters of Total cells, RBC, WBC, MN%, PMN%, linear range for fluids of Total cells 10–20,000 ×10⁶/L, blood count throughput of 60–100 samples/h, supported fluids of CSF, pleural, peritoneal, synovial and reagents of Dedicated body fluid diluent and lysing reagent. Values are indicative of the product class; the exact figures for each configuration are confirmed on the quotation and the calibration documents supplied with the instrument.

Which applications is it used for?

The Automated Hematology Analyzer with Integrated Body Fluid Module is used in cerebrospinal fluid cell counts, pleural and peritoneal effusion assessment, synovial fluid analysis for arthritis and body fluid counts in hematology and pediatrics. Across the wider Automated Hematology Systems class, laboratories also deploy it for high-volume hospital hematology laboratories, consolidated core laboratory workflows and reference laboratories with remote morphology review.

Which standards and certifications apply?

Relevant standards and methods include ISO 15189, CLSI H26-A2, CLSI AUTO10, CLSI EP05, CLSI H20-A2, IEC 61010-1 and IEC 61010-2-101. Certification candidates for this model are CE, ISO 13485 manufacturing and NMPA class II registration; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Installation requires a stable environment with controlled temperature, low dust, adequate floor loading for track sections and uninterruptible power for the controller and middleware server. Verify each module separately before validating the integrated workflow, including barcode read rates, routing accuracy, slide quality and image capture. Document review rules and test them against a representative sample set before go-live, because rule errors affect patient results. Plan daily cleaning of probes and tracks, weekly flow cell and optics checks, slide stainer reagent replacement and periodic replacement of pneumatic parts. Keep a downtime procedure that allows analysis to continue on a stand-alone analyzer if the track or middleware fails, and treat all samples, films and waste as biohazardous.

How do I select the right Automated Hematology Analyzer with Integrated Body Fluid Module?

Specify this variant when the laboratory performs body fluid counts regularly, especially when cerebrospinal fluid volumes are small or when turnaround for meningitis assessment matters. In the RFQ confirm the sample volume, the cells it can reliably count at low concentrations, whether mononuclear and polymorphonuclear differentiation is included, and the availability of body fluid controls. Ask for validation data against manual chamber counts on clinical fluids, not only blood.

How does it compare with other Automated Hematology Systems variants?

Choose an automated hematology system when daily counts exceed several hundred, when film review consumes significant technologist time, or when the laboratory wants to consolidate hematology with other disciplines on a track. Compare systems by which modules are integrated, whether film preparation is triggered automatically by analyzer flags, whether digital images are stored for remote review, and how middleware handles reflex rules. Check throughput of the loader and the analyzer together, because the slower module sets the pace. Confirm reagent and consumable logistics for each module, the floor space and service clearances required, the validation workload at installation, and whether the supplier can support middleware changes locally. Plan the workflow and review rules before purchase, not after.
