Do I need to fast before I get my blood drawn?

Please check your most recent visit note — under the “Testing” section — for your clinician’s specific instructions on fasting.


If fasting is recommended:

- Avoid food, coffee, and tea for 8–10 hours before your draw.

- Stay hydrated—water is encouraged the day before and the morning of your lab visit to make your draw easier and more comfortable.
