In this Ask a Nutritionist episode, dietitian Brandy Buro walks you through the key labs she likes to see at an annual physical, including vitamin D, fasting glucose, insulin, A1C, liver enzymes, and a full cholesterol panel. She also explains advanced heart-health markers, when tests like ferritin or thyroid panels are helpful, and how “optimal” ranges differ from standard “normal” lab ranges. You’ll learn how to prepare for bloodwork, what to ask your doctor for, and how to use your results as a roadmap for better energy, mood, metabolism, and long-term health.
