A 23-year-old woman attends a GP appointment, complaining of a three-month history of feeling “on edge”

A 23-year-old woman attends a GP appointment, complaining of a three-month history of feeling “on edge”. She calls herself a “nervous wreck” and says that as well as feeling constantly worried, she suffers from frequent palpitations, shaky hands, dry mouth, and excessive sweating. She can think of no particular trigger for these symptoms, which can happen at any time. The GP arranges for basic blood tests to be done, requesting a FBC and U&E. 

Based on the case above, what additional blood test should the GP request?
