Clare’s done some more science… XbarM analysis… for the most part tells you
that the blood samples going through your analyser now are from a different
clinic to those that went through half an hour ago…
Clare explains it in
more detail here.
This is (supposed to be) a reflective diary by a (not very) anonymous biomedical scientist who works somewhere in the south of England. One day this diary may well be submitted to the Health and Care Professions Council as evidence of ongoing continual professional development....

26 July 2023 (Wednesday) - XbarM
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”.

19 May 2022 (Thursday) - XN Scattergram Plots
That Clare has done some science again. At first sight it might seem a tad simplistic, but think again. Putting the correct XN cell cloud in the right place on a scattergram… I would seriously have to think this one through… and I’d challenge anyone who would claim it was easy.
30 May 2018 (Wednesday) - XN Training
I had a little training on our new Sysmex XN
system today. It was rather good. Back in the day I would have been the one
doing the training. I’m rather glad I’m not in that position any more…
