Cholesterol Test Preparation Guide
Everything you need to know for accurate results
Why Preparation Matters
Proper preparation ensures accurate cholesterol test results. What you eat and drink before your test, especially if fasting is required, can significantly impact your triglyceride levels and overall results.
Fasting Requirements
Most cholesterol tests require 9-12 hours of fasting. Schedule your test for early morning to make fasting easier.
Hydration is Key
Drink plenty of water during fasting. Avoid other beverages as they can affect results.
Medication Guidance
Continue taking prescribed medications unless your doctor advises otherwise.
