Could it be the Li Hep samples from A/E travelled to the lab via a tube
transport system??

Yes, but in 'reasonable' amounts in the presence of a normal
platelet count.
There also seems to be a small cohort of patients whose WBCs are
particularly fragile when confronted with 'clotting activators'
which also
lead to spuriously high potassium in serum.

But isn't the potassium released from platelets into serum during
the
clotting process?
I still don't understand what was going on with Paul's patient in
Chesterfield.

beware also the patient with thrombocytaemia since platelets
contain
lots of
potassium also

Yes, but...
We had a patient recently with CLL and mega white cell
count. His K
on serum
samples from GP and clinic were always 4 ish, but whenever
he came
to A&E,
which sends Li hep samples, his K would be 10-12. Isn't that
supposed to be
the wrong way around?
