Many thanks for the many responses so far regarding my query
about a lady with high potassiums, who eats 2 bananas a day.
My dietician tells me there is about 3-4 mmol/L potassium per
banana - hardly huge. If bananas are "rich" in potassium, how
much is there in everything else that is eaten in reasonable
quantities?
Possibly the Familial pseudohyperkalaemia (1) due to red cell
leak offers the most likely explanation.
In my long time in the business, unexpected/unexplained high
potassiums (usually late Friday pm) have offered by far the
greatest consternation.
The leaky red cell condition cuts a swathe through the
excellent diagnostic flowcharts for high potassiums which
have been posted on the list in recent times.
Like the Loch Ness Monster, we will never be certain whether
it is there or not, when other possibilities have been
eliminated.

Ps I appreciated the replies which were in a lighter vein
