XN Check

Effective quality control for your haematology laboratory

XN Check is a control material designed specifically for the Sysmex high-end haematology analysers including XR-Series, XN-Series, XN-L Series as well as XN-V and XN-31. It enables a thorough check of the analysers’ technical functions and reagent system for your peace of mind.

More details

Covering a wide clinical range and doing it safely

XN Check is available in three different concentrations, XN Check level 1, level 2 and level 3, covering wide clinical range for monitoring abnormal low and high as well as normal ranges of values. It provides assay data for all diagnostic parameters, including CBC parameters, WBC differential count, immature granulocytes, nucleated red blood cells*, reticulocytes*, and immature platelet fractions*.

Moreover, it includes all levels of reticulocyte maturation – from early stages to mature red blood cells including reticulocyte haemoglobin equivalent (RET-He), so that you can reliably monitor the RET channel. You can be sure that all measurement channels are monitored and under control.

Another important aspect of XN Check – it is also tested according to the highest standards to ensure safety of use.

Peer comparison quality control

Thanks to the networking capabilities of Sysmex haematology analysers, we offer an internet-based peer comparison quality control service – CaresphereTM XQC. You can discover much more on the dedicated webpage.
