XN CHECK

Effective quality control


XN CHECK is a control blood designed specifically for the XN-Series that makes it possible to thoroughly check the analysers’ technical functions and reagent system. It offers effective and reliable internal and external quality control of the XN-Series haematology system.

XN CHECK provides assay data for all diagnostic parameters: eight CBC parameters, WBC differential count, immature myeloid information, nucleated red blood cells and reticulocytes.

Safe and a wide clinical range

XN CHECK is available in three different concentrations. XN-CHECK level 2 covers the normal range, XN-CHECK level 1 is used for the abnormal low range and XN-CHECK level 3 monitors the abnormal high rage.

It is non-reactive for hepatitis B surface antigen, hepatitis C virus (HCV) and HIV1/HIV2 anti-body using techniques specified by the FDA. The careful packaging protects it from evaporation and damage and ensures it is stable for longer.

More information

More information

It includes white blood cells for the differential, reticulocyte fractions and nucleated red blood cells. XN CHECK includes all levels of reticulocyte maturation - from early stages in the HFR area to mature red blood cells so that you can reliably monitor the RET channel. This leads to a distinctive display of all the relevant cell populations in the appropriate scattergram.

Quality control also includes the parameters reticulocyte haemoglobin equivalent (RET-He), immature granulocytes (IG), immature platelet fraction (IPF) and PLT-F. It lets you control all measurement channels.

External quality control

External quality control

Using XN CHECK and the networking capabilities of Sysmex XN-Series analysers, we offer an Internet-based external quality control service – IQAS Online - which is part of the Sysmex Network Communication System (SNCS).

In parallel with the internal QC based on XN CHECK, which remains local on the analyser, results are transferred automatically to an external computer. They are then compared to results of other systems of the same type. Just a few minutes after performing the measurement, a performance comparison to international peer group data is available in addition to the familiar assay value comparison of the internal QC. Individual results can be viewed on the SNCS website after a password-protected log-in specifying your details.

You are informed automatically if results deviate significantly, thus enabling you to take appropriate counter¬measures without delay. SNCS IQAS Online is a unique integration of daily QC and international external quality control in a single common QC measurement. It provides a daily external QC scheme without the need for any additional control material.
