how is blood sugar tested

Blood sugar can be tested using several methods:

• Fingerstick Test: A small drop of blood is obtained by pricking the finger with a lancet. The blood is then placed on a test strip and read by a glucose meter.
• Continuous Glucose Monitoring (CGM): A small sensor is inserted under the skin to measure glucose levels in real-time throughout the day and night.
• A1C Test: This blood test measures your average blood sugar levels over the past 2-3 months. It does not require fasting and is often used to diagnose prediabetes and diabetes.
• Fasting Blood Sugar Test: This test measures blood sugar after an overnight fast and is commonly used to diagnose diabetes.
• Oral Glucose Tolerance Test (OGTT): After fasting, you drink a sugary liquid, and blood sugar levels are tested periodically over the next 2 hours.

Each method has its own purpose and is used based on the specific needs of the patient and the recommendation of a healthcare provider.
