Sysmex XT-1800i Automated Hematology Analyzer​​​​​​​​
Mid Volume Laboratory Solution
Advanced Technology Solutions to Meet Your Laboratory's Needs
Designed to be reliable and efficient, the Sysmex XT-1800i offers medium volume laboratories an automated hematology system that can truly meet and exceed their expectations. The XT-1800i provides CBC and​ differential analysis using the same technologies as the other analyzers in the Sysmex XT-Series and XE-Series lines. Body fluid samples, including CSF, serous fluid and synovial fluid, are analyzed for RBC and WBC counts. A 6-part WBC Differential, including enumerated immature granulocytes (IG% and #), is optional for laboratories who need to reduce smear reviews. The XT-1800i streamlines your workflow by providing testing for up to 80 samples per hour, enabling rapid turnaround time.

Advanced Technology Solutions to Meet Your Laboratory's Needs

The Sysmex XT-1800i Automated Hematology Analyzer utilizes the power of fluorescent flow cytometry and hydrodynamic focusing technologies. Using a unique diode laser bench, Sysmex fluorescent flow cytometry provides the sensitivity needed for measuring and differentiating cell types in whole blood and body fluid samples. Fluorescent technology and hydrodynamic focusing enable the XT-1800i to consistently differentiate normal WBC, RBC and PLT populations from abnormal populations, thereby decreasing the number of manual interventions. The XT-1800i technology provides clinically relevant and reportable parameters.


  • Reportable WBC and RBC counts for all common body fluid sample types (CSF, synovial and serous)


  • Immature Granulocyte count (IG% and #) offers reportable, quantitative results for metamyelocytes, myelocytes, promyelocytes
    • Reduce false positive and false negative rates
    • Obtain result consistency by reducing tech-to-tech variation in reporting manual differentials

Red Blood Cells and Platelets - RBCs and platelets are counted in a dedicated channel using the direct current detection method with hydrodynamic focusing technology to minimize coincidence or recirculation. Automatic discriminators separate the two cell populations based on complex algorithms. The intensity of the electronic pulse from each analyzed RBC is proportional to the cell volume. The hematocrit (HCT) is directly determined based on the count and volume detection of each individual RBC. Even with samples at extremely low or unusually high concentrations, the Sysmex cell counters analyze RBCs and platelets with uncompromised precision and accuracy.
Hemoglobin Analysis - The Sysmex sodium lauryl sulfate (SLS) method for hemoglobin analysis is a non-cyanide method. Hemoglobin is determined in a separate channel, minimizing interference from high leukocyte concentrations. The SLS method shows excellent correlation with the reference method. With very short reaction times, this method is ideal for high throughput analyzers.
Fluorescent Flow Cytometry - Traditional flow cytometry is considered the best method for the differentiation of cell populations. However, it requires the use of costly antigen-antibody reagents and the procedures can be cumbersome and time consuming. Sysmex has refined basic techniques of flow cytometry and uses highly specific polymethine dyes to adapt that sophisticated technology to the high volume and automation requirements of the clinical lab. In order to meet the clinical demands for more accurate routine differentiation of normal and abnormal cells, flow applications using simple but sophisticated fluorescent dyes will continue to be expanded to fit the needs of routine CBC testing.
WBC Differential - Fluorescent labeling is a milestone for the routine WBC differential. Fluorescent measurement reveals the nucleus-plasma ratio of each individually stained cell, enabling the XT-Series analyzers to differentiate 6 reportable WBC populations. The combination of side scatter (inner complexity of the cell), forward scatter (volume) and fluorescence of nucleic acid material determines the classification of each WBC. The XT-Series utilizes an Adaptive Cluster Analysis System (ACAS) instead of conventional discriminators to separate cell populations into well defined clusters. This three-dimensional measurement of WBC provides an accurate and precise differential, even in highly pathological samples.
