Ifeanyichukwu Ifechidere: The Framework for Mastering Coagulation Fundamentals
Ifeanyichukwu Ifechidere, Specialist Biomedical Scientist at Sheffield Teaching Hospitals NHS Foundation Trust, shared a post on LinkedIn:
“Coagulation is the one area most biomedical scientists secretly hope stays quiet.
Because when it doesn’t – the panic is real.
Most BMS understand coagulation just enough to get through the shift.
- Results in range – move on.
- Results out of range – repeat it and pray.
That feels like enough. Until it isn’t.
The coag lab doesn’t warn you before it humbles you.
It just arrives.
A critically prolonged APTT on a surgical patient going to theatre in two hours.
A mixing study that partially corrects and you don’t know what that means.
A clinician asking ‘could this be a lupus anticoagulant?’ – and the silence on your end says everything.
In that moment – years of running samples mean nothing.
What matters is whether you can think.
I once worked with a BMS – six years experience – who told me:
‘If someone asks me to explain why a mixing study matters, I still go blank. I just smile and say I’ll look into it.’
Six years. Still disappearing when the hard questions came.
Not because she wasn’t capable – because nobody had ever given her the framework to think it through.
So she stayed in the shallow end.
Competent enough to function. Not confident enough to lead.
Then she decided surface level was no longer good enough.
She went back to fundamentals. Built her understanding layer by layer.
Within weeks – she stopped dreading difficult samples and started owning them.
She became the scientist everyone brought the hard cases to.
That transformation has one starting point.
Coagulation fundamentals. Properly understood. Finally.
That’s exactly what I wrote Coagulation Fundamentals for Biomedical Scientists for.
- The cascade explained the way it should have been taught
- A clear framework for approaching abnormal results
- Mixing studies – interpreted with confidence
- Case-based thinking you can apply from your next shift
One ebook. One decision. One shift in how you see coagulation forever.
Be that scientist.”
