Fasting
Lipid profile and fasting glucose need 8–12 hours without food. Water is fine and helps the draw.
Medicines
Keep taking regular medicines unless your doctor says otherwise; tell the phlebotomist what you take.
Timing
Book early-morning home collection for fasting tests so you can eat right after.
