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.
