Compact Point-of-Care Hematology Analyzer

What is the Compact Point-of-Care Hematology Analyzer?

A compact point-of-care hematology analyzer performs a complete blood count with a 3-part white blood cell differential from microliter samples using impedance counting. It is used in clinics, small hospitals and field settings needing rapid CBC results without a full laboratory.

Overview

This variant is a small benchtop or portable analyzer that measures up to 18 to 22 parameters including WBC, RBC, HGB, HCT, MCV, PLT and a three-part differential of lymphocytes, mid-sized cells and granulocytes. It uses electrical impedance counting through a micro-aperture and cyanide-free hemoglobin measurement by photometry. Sample volume is 10 to 20 microliters in capillary or pre-dilute mode, with throughput of 30 to 60 samples per hour. Reagent consumption is low and packs can be stored at room temperature. The device weighs 3 to 10 kg and includes a touchscreen, printer and memory. The limited differential means flagged abnormal results need review with a larger analyzer or blood film. Regular cleaning and quality control maintain accuracy.

How does it work?

Point-of-care devices miniaturize laboratory methods into compact instruments and single-use test formats. Lateral flow immunoassays wick the sample along a membrane where labeled antibodies form visible or fluorescent lines at capture zones, and a reader quantifies line intensity. Electrochemical biosensors measure current or potential produced by enzymatic reactions on printed electrodes, as in glucose and lactate testing. Cartridge analyzers combine microfluidics with ion-selective electrodes or optical detection for blood gases and chemistry. Coagulation meters detect clot formation by impedance or light scattering changes. Compact hematology analyzers use impedance counting and colorimetric hemoglobin measurement. Built-in quality checks, lot calibration and connectivity support reliable use by non-laboratory operators.

What are the key features?

• Electrical impedance counting with three-part WBC differential
• Up to 18–22 parameters with histograms for WBC, RBC and PLT
• Sample volume of only 10–20 µL in capillary mode
• Cyanide-free hemoglobin measurement by photometry
• Low reagent consumption with room-temperature storage
• Touchscreen, printer and result storage in a compact body

What are the technical specifications?

A typical compact point-of-care hematology analyzer configuration offers parameters of 18–22 incl. 3-part differential, throughput of 30–60 samples/h, sample volume of 10–20 µL (capillary), 20 µL (whole blood), WBC range of 0.0–99.9 × 10⁹/L, HGB range of 0–250 g/L and PLT range of 0–999 × 10⁹/L. 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 Compact Point-of-Care Hematology Analyzer is used in clinic and outpatient CBC testing, emergency bedside blood counts, small hospital laboratories and field and mobile clinics. Across the wider Point-of-Care Diagnostics class, laboratories also deploy it for emergency department rapid testing, primary care clinic testing and anticoagulation monitoring.

Which standards and certifications apply?

Relevant standards and methods include ISO 22870, ISO 15197, ISO 15189, IEC 61010-2-101, CLSI POCT12, CLSI POCT14, ISO 13485 and EN 13532. Certification candidates for this model are CE, ISO 13485 quality system and NMPA registration; each is to be confirmed for the specific configuration before shipment, and certificates are supplied only where they have been issued.

Point-of-care testing is often performed by non-laboratory staff, so governance is essential. Establish a program covering operator training, competency assessment, quality control schedules, external quality assessment and documentation, with oversight from a laboratory. Store strips and cartridges within labeled temperature ranges and check expiry dates. Keep meters clean and disinfected between patients with approved disinfectants, since contamination with blood is a risk. Understand known interferences such as hematocrit, oxygen or medications for each device. Ensure results are transmitted to patient records, and confirm critical or unexpected values with laboratory methods. Comply with local regulations on device use, waste handling and data protection.

How do I select the right Compact Point-of-Care Hematology Analyzer?

Choose a compact hematology analyzer for low-volume CBC testing outside a central laboratory. Specify parameters, differential type, sample volume, reagent storage, throughput, connectivity and flagging capability in the RFQ, and plan a referral route for samples with abnormal flags.

How does it compare with other Point-of-Care Diagnostics variants?

Select by clinical need, operator skill and connectivity. Define the tests needed at the point of care and their required turnaround, then check the analytical performance against laboratory methods for the intended population. Consider sample type and volume, ease of use, cartridge or strip storage, calibration and quality control requirements, and operator lockout and certification features. Connectivity to hospital or laboratory information systems matters for record keeping and oversight. Compare cost per test, including consumables and quality control, with central laboratory testing. Confirm regulatory status for intended use, and arrange training, competency assessment and oversight by the laboratory, following ISO 22870 where applicable. Verify the supplier's ability to maintain consumable supply.
