A 68-year-old man is brought to the ED in March after being found outdoors overnight. He is confused and shivering intermittently. He has a history of alcohol use disorder and lives alone. On exam, his skin is cold to touch and his speech is slurred. Vital signs: - T: 31.8 °C (core, esophageal) - BP: 94/58 mmHg - HR: 42 /min - RR: 10 /min - SpO2: 96% (RA) An ECG shows sinus bradycardia with prominent J (Osborn) waves. After initial stabilization and active rewarming are started, the team considers additional investigations for underlying contributors. Which test is most appropriate to evaluate a reversible endocrine cause that can predispose to hypothermia?
