Sysmex XT-1800i: a reliable haematology analyser for medium-volume laboratories
The Sysmex XT-1800i is an automated haematology analyser that meets the growing needs of modern laboratories facing high workloads and increased demands for accurate and fast results. Developed for medium-volume laboratories, this instrument combines proven technologies with a design focused on productivity and reliability. Its throughput of 80 samples per hour supports an intensive workflow while delivering the comprehensive and accurate results that clinicians need for diagnosis and treatment monitoring.
The integration of fluorescent flow cytometry and hydrodynamic focusing provides exceptional cell differentiation quality. These technologies enable accurate identification of normal and abnormal cell populations, reducing the need for manual rework and minimising interpretation errors. The XT-1800i also features a cyanide-free haemoglobin assay method using SLS reagent, ensuring safe and environmentally friendly analysis while providing reliable measurements even in the presence of interferences such as hyperleukocytosis or lipaemia.
Clinical parameters and analytical performance of the Sysmex XT-1800i
The Sysmex XT-1800i offers a comprehensive parameter menu, including red blood cell, platelet and white blood cell counts, as well as direct measurement of haematocrit and haemoglobin. Its ability to analyse samples with extreme, low or high concentrations ensures consistent accuracy. For red blood cells and platelets, the device uses impedance detection coupled with hydrodynamic focusing, eliminating interference due to cell coincidence.
Differential leukocyte analysis benefits from a three-dimensional approach combining lateral diffusion, forward diffusion and fluorescence, enabling reliable and reproducible classification of different leukocyte subpopulations. This approach ensures high sensitivity even in critical samples where leukocyte concentration is particularly low. The immature granulocyte (IG) detection option provides an additional useful indicator for monitoring infectious and inflammatory conditions, enabling better clinical guidance.
Productivity, ergonomics and workflow integration
Designed to integrate easily into the laboratory workflow, the Sysmex XT-1800i combines speed, ergonomics and digital features. With a reduced sample volume (40 to 150 µL depending on the mode), it is suitable for laboratories handling small volumes, such as paediatric or capillary samples. Its internal memory can store up to 10,000 results with associated graphics, facilitating traceability and quality monitoring.
The integrated quality management system includes comprehensive control files with Levey-Jennings charts and online monitoring via the Insight programme. The latter enables inter-laboratory performance evaluation and permanent access to comparison data. In addition, the XT-1800i is compatible with Sysmex WAM software, enhancing data flow efficiency and speeding up the transmission of results to clinicians.
The XT-1800i is therefore an essential tool for any laboratory seeking to combine analytical accuracy, reliable results and optimised workflow. With its robust design and intuitive interface, it ensures smooth operation and simplified maintenance, contributing to continuity and quality of patient care.
