Fasting Guidelines & Preparation for Accurate Blood Tests

Accurate laboratory results begin before the needle touches the vein. Pre-analytical variations account for more than 60% of diagnostic discrepancies.

Crucial preparation rules:

• Overnight Fasting: For Lipid Profiles and Fasting Blood Sugar, 8 to 12 hours of overnight fasting is necessary. Fasting longer than 14 hours is counter-productive because the liver releases stored glycogen and ketones.
• Hydration is Encouraged: Plain water does not break your fast and ensures your veins are supple and easier to sample smoothly.
• Morning Medication: Always consult your physician before pausing daily thyroid, blood pressure, or diabetes medications on test morning.
