Translate a GP Referral Letter Into Plain Language

A referral letter has landed and it's full of terms that mean something to a consultant and nothing to you. This explains in plain language what your GP is concerned about or investigating, clarifies the medical words and abbreviations, and tells you what the next step is. You go to the appointment understanding why you're there.
