ABSTRACT
A 60-year-old man was asked to attend the emergency department following an abnormal routine blood test earlier that day. He had been feeling well recently; the blood test was taken following recent changes to his regular medications. His past medical history was significant for hypertension only. His current medications were ramipril 5 mg OD and spironolactone 25 mg OD. He worked as a retail manager, did not drink alcohol regularly and had never smoked.
