Fasting for a blood test? Here’s what you need to know!
If you’ve been asked to fast before your blood test, a little preparation can help ensure accurate results.
Drink plenty of water! Staying well hydrated can make blood collection easier.
•Fast for 8–12 hours, or as directed by your doctor.
•Plain water is encouraged and does not break your fast.
•Avoid food, coffee, tea, juice and other drinks during your fasting period.
•Avoid chewing gum and smoking while fasting.
•Continue your usual medications unless advised otherwise by your doctor.
Remember, not all blood tests require fasting!
If you’re unsure if you need to fast, check with your doctor or our nursing team before your appointment
