Fasting helps ensure the most accurate results for certain blood tests—especially those measuring glucose, triglycerides, and cholesterol. Eating before your test can temporarily raise these levels, leading to misleading results.
If fasting is required, we’ll let you know in advance, usually asking you to avoid food and drink (except water) for 8–12 hours before your test.
Your privacy and security are our top priorities. Here's how we handle your data:
