Blood Sugar Testing
Take a proactive step toward understanding your metabolic health. This panel includes two essential blood tests: Fasting Blood Glucose (FBS): Measures your blood sugar level after fasting. Hemoglobin A1c (HbA1c): Reflects your average blood sugar levels over the past 2–3 months. Together, these tests help screen for prediabetes and diabetes, monitor blood sugar regulation, and provide a baseline for tracking metabolic health over time. Fasting required: Typically 8 hours before blood collection. Water is permitted.
