Do I have to fast, and can I drink water?
the desk replies — Fasting of 8 to 12 hours is standard for lipid and glucose testing, but plain water is allowed and actively encouraged — it improves both the draw and the accuracy of the sample. Coffee, tea, juice and chewing gum all count as breaking the fast. Confirm the exact requirement for your panel when booking, since many tests need no fasting at all.
