A 72-year-old woman is brought to A&E

A 72-year-old woman is brought to A&E. Her family tells you that she has become increasingly confused over the past couple of days. They are not aware of her having had any recent illness, and she is generally fit and well. Her only past medical history of note is breast cancer, which was treated surgically 10 years ago. Blood tests are done at triage, with a FBC and U&E being sent. The patient is agitated on assessment and not orientated to time, place or person.

Which THREE of the following tests should be added to the blood samples? Select THREE options only.
