Is fasting required before my blood test?
Fasting is often necessary for accurate blood test results. Food and beverages can temporarily affect blood chemistry levels, leading to inaccurate measurements.
Tests that commonly require fasting include:
- Hormone tests and panels
- Cholesterol, glucose, and metabolic tests
- Deficiency tests (Iron, Vitamin B12, etc.)
- Thyroid tests
Your lab order will specify fasting requirements. Follow these instructions carefully for accurate results.
