It is the end of the week and I am near clearing my inbox of results. Hypokalaemia is identified in a patient and I duly call them, take a brief history, and no clear cause is identified.

It is mild and having printed a prescription for potassium supplements, arranging for it to be sent to the pharmacy, leaving a follow-up pathology form at the desk and arranging a follow-up appointment within a week, I’m all set to go home.
