Always check with your physician for specific instructions prior to blood draws. Tests requiring a fasting specimen include (but are not limited to): Glucose, Lipid Panels, and Comprehensive Panels. It is required that you fast for 12 - 14 hours prior to blood draws. This means no consumption of tea, coffee, juices, or food.

Always refer to your physician if you have questions regarding pre-test preparations that may be unique to your specific situation.
