Fasting for Your Lab Appointment

Fasting before your lab appointment helps ensure the most accurate results.

Fast for 8 hours

• Arrive fasted for 8 hours before your blood draw.
• Water is okay.
• Fasting provides the clearest insight into your biomarkers. Eating beforehand can affect certain results.

Stay well-hydrated

• Drinking water before your appointment can make blood draws easier.
• If possible, aim for at least 32 oz of water before your appointment.
• Proper hydration can also support more accurate urinalysis results.

Schedule a morning appointment (if possible)

Morning appointments can help support the most accurate readings for some hormone levels.
