When it comes to evaluating a person's health, doctors use a wide variety of tests and measurements called biomarkers. These can range from simple readings such as blood glucose levels to sophisticated genetic analyses. Learn how biomarkers can chart the direction of wellness and provide benchmarks for personal health goals.
Diagnostic imaging lets doctors look inside your body for clues about a medical condition. A variety of machines and techniques can create pictures of the structures and activities inside your body. The type of imaging your doctor uses depends on your symptoms and the part of your body being examined. Find out what types of imaging are available.
