The Sysmex XT-4000i Automated Hematology System utilizes the power of fluorescent flow cytometry and hydrodynamic focusing technologies. Using a unique, state-of-the-art, 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-4000i to consistently classify normal WBC, RBC and PLT populations from abnormal populations, thereby decreasing the number of manual interventions.
