Translate a Confusing NHS Letter Before an Appointment

NHS letters can leave you unsure what the appointment is even for, let alone what to do beforehand. This tells you what type of appointment it is, what you're being asked to do before or on the day, and what to bring. It won't interpret results or give clinical advice, just the practical bits. For patients with a letter and a few questions.
