The Fasting Glucose test measures the level of glucose in your blood after an overnight fast. This test is crucial for assessing your body's ability to regulate blood sugar levels, which is essential for overall metabolic health. Abnormal fasting glucose levels can indicate insulin resistance or diabetes, which can lead to various health complications. Understanding your fasting glucose levels can help you and your healthcare provider make informed decisions about your diet, lifestyle, and potential interventions to improve your health.
