Effective quality control

The XN CHECK BF is a control blood designed specifically for the body fluid mode on the XN-Series. It makes it possible to check thoroughly the analysers’ technical functions and reagent system. It also allows effective and reliable internal and external quality control of the body fluid mode for the XN-Series haematology system.

Safe and a wide clinical range

XN CHECK BF is the material of choice for quality control for all diagnostic parameters of the body fluid mode and enables thorough monitoring of the body fluid measurement. It is available in two different concentrations. 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.

External quality control

Using XN CHECK BF 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 BF, 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 so that you can 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.
