Patient Instructions
When you come for your lab test, be sure to bring the lab test order from your provider and your insurance card. 

Fasting 
The laboratory defines fasting as no food, drink (water is OK and encouraged), or smoking for 12 hours before blood is drawn. Patients may still take medication with small amounts of water, unless your provider has given other instructions. Candy, gum, mints, and coffee should not be consumed if your labs require fasting.
