74-year-old man has been feeling lethargic for the past week, he has troubles with urination and mild peripheral oedema in his ankles. He has had benign prostatic hypertrophy previously but is otherwise usually very fit and uncomplaining. He was sent to the department of internal medicine by his GP, where they have performed his blood tests. You are in the role of doctor of internal medicine, what measures would you undertake after seeing results?
