EDAN H90S with NRBC 6‑Part Hematology Analyzer

The EDAN H90S is a high‑performance 6‑part differential hematology analyzer built on an advanced fluorescent 3D flow cytometry platform. Designed for mid‑ to high‑volume clinical laboratories, it delivers precise CBC and differential analysis with fully standardized workflows and a throughput of up to 100 tests per hour.

What sets the H90S apart is its true 6‑part differential—the classical 5‑part WBC differential plus fully validated Immature Granulocytes (IG) as the sixth white blood cell subpopulation. Combined with automated NRBC reporting in every CBC test, optional RET (reticulocyte) detection, and a comprehensive suite of RBC and platelet indices, the H90S delivers the clinical insights laboratories need for confident diagnosis.

Key Features & Benefits

True 6‑Part Differential with Immature Granulocytes

The H90S goes beyond traditional 5‑part differentials by providing a true 6‑part differential that includes Immature Granulocytes (IG) with full validation. The six WBC subpopulations reported are:

• Neutrophils (NEU) – key indicator of bacterial infection

• Lymphocytes (LYM) – essential for viral infection and immune status

• Monocytes (MON) – elevated in chronic inflammation

• Eosinophils (EOS) – critical for allergy and parasitic infection detection

• Basophils (BAS) – valuable for allergic reactions

• Immature Granulocytes (IG) – the sixth population, providing early warning of infection, inflammation, or bone marrow response

This expanded differential enables earlier detection of left shift and more comprehensive assessment of hematological status.

Automated NRBC Reporting – No Extra Steps, No Extra Cost

The H90S reports Nucleated Red Blood Cells (NRBCs) in every CBC test with no additional steps, reagents, or operator intervention required. NRBC results are reportable and do not require WBC correction—streamlining routine workflows while preventing falsely elevated WBC and lymphocyte counts caused by undetected NRBCs.

Fluorescent 3D Flow Cytometry Technology

The H90S utilizes fluorescent 3D analysis combining forward scatter, side scatter, and side fluorescence to assess cell size, morphology, and nucleic‑acid content. This multi‑parameter approach ensures:

• Precise WBC measurement with excellent performance for 5‑part and 6‑part differentials

• Enhanced and optimized flagging for left shift, atypical/abnormal lymphocytes, and blasts

• Accurate RET, DIFF, and NRBC results

Optional RET Channel for Advanced Anemia Management

The H90S comes with an optional RET (reticulocyte) channel that provides comprehensive indices for anemia assessment and treatment monitoring:

• IRF (Immature Reticulocyte Fraction) – indicator of reticulocyte production

• RHE (Reticulocyte Hemoglobin Equivalent) – assesses iron incorporation into hemoglobin

• LFR/MFR/HFR – reticulocyte maturation fractions providing a basis for anemia diagnosis and detection

• InR (Infected RBC) – assists in malaria screening

Comprehensive Platelet Solution

The H90S offers a multi‑technology approach to platelet counting:

• PLT‑I – improved impedance‑based platelet counting

• PLT‑O – optional optical fluorescent platelet counting

• PLT‑A – AI‑driven Smart Computing

This combination resolves most interferences including RBC fragments, microcytes, and platelet clumps, while improving low‑count accuracy.

Expanded RBC Indices

Beyond standard RBC parameters, the H90S provides advanced indices for anemia and infection screening, supporting more comprehensive patient assessment.
