A 62-year-old man has been brought to A&E by a concerned member of the public (2)

A 62-year-old man has been brought to A&E by a concerned member of the public. He was found wandering in a hayfield in the early hours of the morning and appears to be very confused. He seems to be unbalanced when he walks, and the member of the public did wonder whether he had just been drinking, as he smells slightly of alcohol. The patient has had many different attendances for alcohol intoxication at A&E. At triage, he has had blood taken for a FBC and U&Es, and a urine sample sent for microscopy, culture and sensitivities, and toxicology.

In this case, what additional blood test is indicated?
