Do I need to fast before a blood test?

It depends on the type of blood test. Basic metabolic panels and CBCs usually do not require fasting. However, lipid panels and fasting glucose tests typically require 8-12 hours without food.

How long does a blood test take?

The blood draw itself usually takes less than 5 minutes. Results are typically available within 1-2 business days.

You may feel a brief pinch when the needle enters your skin. Most people find the discomfort minimal and temporary.
