Here’s
an interesting article from the Sysmex Academy. The
XbarM control program.
In theory it is a brilliant idea… the average result of all the samples going through the lab should remain unchanged over time.
It probably does… from one week to the next. However all the time patient samples from specific clinics arrive together there are going to be biases. And so XbarM is of arguable relevance. The trouble is that because the analyser comes with this tool, people will use it. With no regard to how it is being used. And so the old maxim comes into play – “if you look for trouble, you will find it”.
