Fluorescence flow cytometry for high quality haematology analysis
More than blood alone – a dedicated mode for body fluids
Extended Diagnostic Capabilities on board (IG, Ret, Ret-He, IRF)
Sysmex Gold standard reticulocyte technology for monitoring erythropoietic status (Ret, Ret-He, IRF)
Online QC, optimised workflow, cost-efficient reagent consumption

The XT-4000i really is an outstanding haematology analyser. Using Sysmex’s unique fluorescence flow cytometry, the analyser looks at RNA/DNA content, cell size and inner cell complexity rather than just cell size. This generates remarkably accurate results and a superb WBC differential.

For those who need special capabilities, the XT-4000i has a separate, dedicated rue body fluid mode. It has Sysmex’s famous gold standard reticulocyte technology on board as standard for monitoring erythropoietic status (Ret, Ret-He, IRF), as well as true quantitative IG counting instead of mere flagging. And it is particularly precise for RBC and PLT parameters thanks to hydrodynamic focusing.

The analyser is practical and can be adapted to your own particular workflow. You will appreciate its cost-effective reagent consumption, and the fact that you can adapt the diagnostic sensitivity to your own laboratory needs through its unique Q-flags. You can also attach it to our network communication system for online quality control.
