An interesting case. Clearly microscopically there is a dimorphic population from a blood transfusion in November

I’m well aware of the vagaries of haematological analysis following blood transfusions, but know nothing of how biochemistry is affected. From a conversation with a consultant clinical chemist, it would seem that there is little information available in scientific literature.
Given that any parameter’s post transfusion level is similar to the pre-transfusion level, then it’s safe to say there’s been no effect.
Given that there is a difference, then how much is due to the fact that the patient is critically ill (after all, they needed a blood transfusion!) and how much is due to the transfusion itself would seem to be a matter of conjecture.
One lives and learns…
