The Sysmex XN-550 is a compact, fully automated hematology analyzer designed for small to mid-sized laboratories, offering advanced diagnostics with high efficiency. It provides a 5-part/6-part differential analysis with high accuracy, delivering reliable Complete Blood Count (CBC) results along with advanced clinical parameters. The analyzer uses fluorescence flow cytometry, hydrodynamic focusing, and cyanide-free SLS technology, ensuring precise and safe hemoglobin and cell analysis. It features an automated sample loader with continuous loading capability, along with rerun and reflex testing functions, which significantly improve workflow and reduce manual intervention. The system also includes an integrated IPU (Information Processing Unit) with a color touchscreen, eliminating the need for an external computer and making operation user-friendly. The analyzer requires only a small sample volume (25 µL), making it suitable for pediatric and low-volume samples, while still maintaining high accuracy. It offers high throughput of up to 60–70 samples per hour, ensuring efficient laboratory performance. Additionally, the XN-550 supports optional reticulocyte (RET) and body fluid analysis, expanding its diagnostic capabilities. It provides advanced clinical parameters such as immature granulocytes (IG) and enhanced RBC/PLT analysis, improving diagnostic confidence. The system is compact, scalable, and upgradeable, allowing laboratories to expand functionality as needed. It also includes intelligent rack sampling, onboard rules for rerun/reflex testing, and high data storage capacity, ensuring smooth and smart laboratory operations. The XN-Series technology offers advanced hematology analysis in a compact footprint, making it ideal for lower-volume laboratories. It supports both open and closed tube sampling with an automated sample loader for enhanced workflow efficiency. The system utilizes fluorescence flow cytometry for WBC differentiation, a direct current impedance method with hydrodynamic focusing for RBC and PLT measurement, and a cyanide-free SLS method for hemoglobin analysis. It includes multiple channels such as XN-DIFF, WBC, RET (optional), and XN-BF (optional), enabling comprehensive testing capabilities. The analyzer measures a wide range of parameters including WBC, RBC, HGB, HCT, MCV, MCH, MCHC, PLT, RDW-SD, RDW-CV, MPV, NEUT, LYMPH, MONO, EO, BASO, and their respective percentages and counts. Optional reticulocyte and body fluid parameters further expand its diagnostic scope. With a throughput of up to 60 samples per hour in whole blood mode, the system ensures efficient processing. It requires minimal sample volume, with 25 µL for whole blood and 70 µL for pre-dilute and body fluid modes. The analyzer provides excellent linearity ranges for WBC, RBC, and PLT measurements, ensuring accuracy across a wide spectrum. Quality control is maintained through XN-L CHECK™ or XN CHECK™ systems. The instrument is compact in design, with dimensions of 17.72 inches (W) × 25.98 inches (D) × 17.72 inches (H) and a weight of 116.84 lbs, along with a user-friendly screen size of 10.5 inches (W) × 9.5 inches (D) × 8.25 inches (H). #FullyAutomated #AutomationTechnology #SmartDiagnostics #LabAutomation #HematologyAnalyzer #MedicalTechnology #HealthcareInnovation #DiagnosticSolutions #SmartLaboratory #AdvancedDiagnostics #AutomatedSystems #EfficientWorkflow #ClinicalDiagnostics #LabEquipment #NextGenHealthcare
