Some common blood tests that typically require Fasting include:
- Lipid panel: This test measures cholesterol and triglyceride levels in the blood.
- Glucose test: Fasting blood sugar levels are tested to screen for diabetes.

While Fasting is typically recommended for certain tests, there are exceptions to the Fasting guidelines. Some tests do not require Fasting and may be affected by food consumption.
